This software release contains critical updates to UR20 and UR30 robot firmware which significantly improves the monitoring and operation of the brakes and motors. This optimizes robot and brake performance and increases longevity and reliability of the robot and should be considered a MANDATORY update.

This release also supports e-Series and brings several new features including Flexible Ethernet/IP adapter introduced in PolyScope 5.15.0.

PolyScope GUI

Added support for UR20 to Remote TCP URCap. UR20 owners must update to SW 5.15.1 and Remote TCP URCap v1.4.0-build2 to use remote TCP features.

Flexible Ethernet/IP adapter

Interface for define_bit method on reader, and writer handles was changed. Size of the bit field was moved from second to last parameter, and default was set to 1.

# definition in 5.15.0
define_bit(offset, bitfield_width, bit_number, data_name)
?
# definition in 5.15.1
define_bit(offset, bit_number, data_name, bitfield_width = 1)

?define_bit(offset, bitfield_width, bit_number, data_name)

Method defines individual label in assemblies exchanged with PLC. Labels are used for writing and reading process data in URScript.

Parameters:

offset: Integer, position of the data in assembly in bytes
bit_number: Integer, bit number in a word. 0 = least significant bit. Depending on the bitfield_width most significant bit will be 7, 15, or 31.
data_name: String, label
bitfield_width: Integer, can be 1, 2 or 4 representing bit in byte, word, or double word. Default bit field width is 1 byte.

NOTE: Overlapping bit definitions are not allowed.

Example:

# set label "comm_check" to bit 0 in byte 0
# of the assembly
cnc_status.define_bit(0, 0, "comm_check")
?
# set label "door_opened" to but 9 in word starting
# on byte 16 of the assembly
cnc_status.define_bit(16, 9, "door_opened", 2)

Bug Fixes

PolyScope GUI

Payload Transition Time

We added a new input field in the Set Payload node, which allows users to define a duration for a payload change.

Setting a transition time larger than zero prevents the robot from doing a small "jump" when the payload changes and is easier on the joints. This is useful when picking up or releasing heavy objects or using a vacuum gripper.

Note that the transition time is now also part of the action for the "Set Now" button.

Max force for elbow and tool

The maximum value for "Tool Force" and "Elbow Force" in "Robot limits" can now be set to a maximum of 400N instead of 250N. This change only applies for UR10, UR16 and UR20.

Improved EtherNet/IP installation screen

The layout of the EtherNet/IP installation screen has been improved and aligned with the PROFINET installation screen.

Improved Conveyor Tracking installation screen

The layout of the Conveyor Tracking installation screen has been improved.

In the configuration of linear conveyors, the previous "Reverse" direction button has been replaced with a checkbox, so that it is easy to see whether the direction of the selected Line feature is reversed.

URCap Software Platform

URCap API:

Added support for payload transition time

URCaps can create Set Payload node configurations with a specified transition time
URCaps can read the transition time of a Set Payload node configuration?
API changes (package com.ur.urcap.api.domain.program.nodes.builtin.configurations.setpayloadnode):

New methods?createSelectionConfig(Payload, Time,?ErrorHandler<Time>) and createCustomParametersConfig(Mass, Position, Time, ErrorHandler<Time>) in the existing PayloadNodeConfigFactory interface
New getTransitionTime() method in the existing SelectionPayloadNodeConfig and CustomParametersPayloadNodeConfig interfaces

Added support for new robot types

Extended the existing?RobotType enum in the RobotModel interface with the new UR20 and UR30 robot types
Deprecated the?getRobotSeries() method and the RobotSeries enum in the RobotModel interface
- The?RobotType enum will no longer be extended with new values when new robot series (generations) are introduced.
- The getRobotSeries() method will return the UNKNOWN enum value, if the underlying robot does not belong to either the CB3 or e-Series robot series. This will, for instance, be the case, if the robot is a UR20. The method can only be used to determine, if a robot is a CB3 robot.?
- For more information, see the Javadoc for the?getRobotSeries() method.

Note:

URCap SDK:

URCap?Samples

Improved readability of the POM file (pom.xml) for all samples
Updated the?newURCap.sh?script to the generate new URCap projects with the improved POM file format
Improved?the My Daemon Swing sample:

Simplified the code and improved readability
Improved the handling of the communication with the daemon and updating of the UI
Changes are located in the code for both the C++/Python daemon and the Java URCap bundle

Controller

Introduced support control box version 5.5 for e-Series robots

Structs (complex data types) - Release for production

In URScript, a set of variables can be aggregated into struct, and thus transferred and stored as a single variable.

Structs can be obtained through multiple means:

Using the struct() function

Executing an RPC call that returns a struct

The struct function takes one or more named arguments, and each argument name becomes a member in the struct. All values must be initialized by value, and the type of the value cannot be changed subsequently.

Create a struct:

myStruct = struct(identifier1 = 1, identifier2 = 2, myMember = "Hello structs", listMember = [1,2,3])

Use a member:

myVar = myStruct.myMember

Variable length lists

A list object in URScript has two attributes: length and capacity. The length indicates how many elements the list currently holding. The capacity tells how many elements the list can hold maximum. Once declared, the capacity of the list cannot be changed.

Examples of struct and list manipulation could be found in URScript manual and support article "URScript examples for manipulating structs and lists".

estimate_payload URScript function

Allows the payload mass and center of gravity to be estimated inside a robot program, based on a list of poses and force torque recordings. An example of this program can be found in the estimate_payload urscript function article.

Flexible Ethernet/IP adapter in URScript - Engineering Preview

NOTE: Feature is not recommended for production use. Script API and functionality can change, and production version will be released in the next major release. Contact Universal-Robots application engineer for further support.

This functionality allows programmer to add custom Ethernet/IP connections on top of connections that contains Universal-Robots real-time data.

Interface consists of 2 parts:

Configuration interface over XML-RPC to enable the functionality.
URScript functions to read and write structured data over connection assembly T→O, and O→T objects.

Functionality is intended to be used as a platform feature. It can be built into URCaps, or used directly from URScript.

One example of EDS file with "CNC" connection that contains custom Robot→PLC (T→O) and PLC→Robot (O→T) assemblies is available in UniversalRobot_CNC.eds. Both assemblies are 210 bytes long, and have instance id's 101, and 111 respectively.

Performance

It is recommended to consider performance limitation before integrating custom Ethernet/IP adapter with PLC Scanner. Performance limits can be changed in the final production release. Contact Universal-Robots support if following limitations are preventing implementation of Ethernet/IP connectivity in customer application.

All read and write operations are executed on non-realtime threads. In internal tests read a write turnaround cycle with PLC RPI set to 5ms was on average 40ms. Maximum at 90ms.

This implementation is not recommended for application requiring data update rates below 20ms.

Maximum recommended assembly size is 1000 bytes. This engineering preview does not limit sizes.

Configuration interface

Ethernet/IP service exposes XML-RPC server on port 40000.

add_configuration(Robot→PLC instance id, Robot→PLC assembly size, PLC→Robot instance id, PLC→Robot assembly size)

Function creates one input, and one output assembly that typically forms a Ethernet/IP connection object.

Parameters:

Robot→PLC instance id - Integer, unique instance ID
Robot→PLC assembly size - Integer, assembly data size in bytes
PLC→Robot instance id - Integer, unique instance ID
PLC→Robot assembly size - Integer, assembly data size in bytes

Returns:

True if new assembly was created
False when one of the assemblies already exists, or parameter error.

After function is called, external Ethernet/IP Scanner (on PLC, or CNC machine) can use new connection. Some PLCs require connection object to be defined in EDS (Electronic Data Sheet) file. Separate guide is available on request explaining how to add custom connections, and assemblies to existing Universal Robots EDS file.

NOTE: Universal Robots built-in assemblies 100, and 112 cannot be overwritten. Attempt to configure those assemblies will result in an error.

Example code for adding custom Ethernet/IP from URScript

# Before Start program section
?
# create XMLRPC connection to Ethernet/IP service
globl eip_handle=rpc_factory("xmlrpc", "http://127.0.0.1:40000/RPC2")
?
# one input, and one output assemblies will be available in Ethernet/IP
# adapter after the call
global result = eip_handle.add_configuration(101, 210, 111, 210)
?
# dispose XMLRPC connection handle
eip_handle.closeXMLRPCClientConnection()
?
# pause for 1s while Ethernet/IP service is configuring data exchange files for new assemblies
sleep(1)
?
# next data layout for read and write should be configured

URScript interface

Payload data exchanged through the connection is accessible using read and write handle objects. Typically handle would be opened once in "Before Start" section of the program (or by script contributed by URCap installation contribution), then in the same section data layout will be defined. Afterwards individual reads and writes can be made with methods on the configured handles.

eip_reader_factory(assembly_name, data_size)

Opens handle to PLC→Robot data. Typically placed in "Before Start" section of the program.

Parameters:

assembly_name - string representation of instance id.
data_size - size of the assembly data in bytes

Returns:

handle object

The handle will provide a read only access to the assembly data.

Example:

# Open handle to PLC→Robot assembly with instance id 111, and data size 210 bytes.
global cnc_status = eip_reader_factory("111", 210)

eip_writer_factory(assembly_name, data_size)

Opens handle to Robot→PLC data. Typically placed in "Before Start" section of the program.

Parameters:

assembly_name - string representation of instance id.
data_size - size of the assembly data in bytes

Returns:

handle object

The handle will provide a write only access to the assembly data.

Example:

# Open handle to Robot→PLC assembly with instance id 101, and data size 210 bytes.
global cnc_command = eip_writer_factory("101", 210)

Methods on handles

Handles are used to define underlying assembly memory layout, and afterwards read and write data.

Methods are invoked on handles using '.' operator. Methods are grouped in 2 families:

memory layout definitions: informing handle on how data is visible to the external device, and assigning labels.
All methods in this family start with "define_...".
data access methods: read and write process data.

Examples:

cnc_status.define_bit(0, 1, 0, "comm_check")
status = cnc_status.read("comm_check")
cnc_command.define_uint8(6, "program_number")

define_uint8(offset, data_name), define_uint16(offset, data_name), define_int16(offset, data_name), define_float32(offset, data_name),?define_int32(offset, data_name)?

Methods define individual labels in assemblies exchanged with PLC. Labels are used for writing and reading process data in URScript.

Parameters:

offset: Integer, position of the data in assembly in bytes
data_name: String, label

NOTE: Overlapping data definitions are not allowed, except for overlap with bit fields.

Examples:

# set label "service_code" to byte 11 of the assembly
cnc_status.define_uint8(11, "service_code")

define_bit(offset, bitfield_width, bit_number, data_name)

Method defines individual label in assemblies exchanged with PLC. Labels are used for writing and reading process data in URScript.

Parameters:

offset: Integer, position of the data in assembly in bytes
bitfield_width: Integer, can be 1, 2 or 4 representing bit in byte, word, or double word.
bit_number Integer, bit number in a word. 0 = least significant bit. Depending on the bitfield_width most significant bit will be 7, 15, or 31.
data_name: String, label

NOTE: Overlapping bit definitions are not allowed.

Example:

# set label "comm_check" to bit 0 in byte 0 of the assembly.
cnc_status.define_bit(0, 1, 0, "comm_check")
# set label "door_opened" to bit 9 in word starting on byte 16 of the assembly.
cnc_status.define_bit(16, 2, 9, "door_opened")

define_uint8_array(offset, length, data_name), define_uint16_array(offset, length, data_name), define_int16_array(offset, length, data_name), define_float32_array(offset, length, data_name),?define_int32_array(offset, length, data_name)

Methods define individual labels in assemblies exchanged with PLC. Labels are used for writing and reading process data in URScript.

Parameters:

offset: Integer, position of the data in assembly in bytes
length: Integer, number of elements of the array with base size specified by the data type (e.g. for define_uint16_array length = 4 will use 8 bytes)
data_name: String, label

Examples:

# set label "work_number" to 32 byte long array starting at byte 48 in the assembly
cnc_command.define_uint8_array(48, 32, "work_number")
# set label "axes_offset" to 3 words (6 byte long) array starting at byte 120 in the assembly
cnc_command.define_int16_array(120, 3, "axes_offset")

define_string(offset, length, data_name)

Parameters:

offset: Integer, position of the data in assembly in bytes
length: Integer, number of characters in the string. String should be terminated with 0 if it's shorter than length.
data_name: String, label

read(data_names)

Method reads one or more data labels written by external PLC. Last data is read in non-blocking way.

Parameters:

data_name:

Single string - one data label to read. Method returns basic data type.
Array of strings - multiple data labels to read. Method returns structure with fields named with data labels.

Examples:

# reads single bit to comm_check URScript variable
comm_check = cnc_status.read("comm_check")
# reads multiple fields that can be accessed as service_request struct members)
service_request = cnc_status.read(["door_closed", "service_code"])
if(service_request.door_closed):
? ? do_service_code(service_request.service_code)
end

write(data_struct)

Method writes one or more data labels to the memory read by external PLC.

Parameters:

data_struct: Struct where member names are data labels, and values are data contents

All labels in struct are guaranteed to be written at the same time to assembly data.

NOTE: method will do a range check based on the type of the data label. Numbers exceeding data type will stop a program with runtime exception.

Examples:

# set work_number label array, and search_start bit
cnc_command.write(struct(work_number = [1, 2, 3, 4], search_start = True))
cnc_command.write(struct(door_open = True))
# define global struct, and reuse in calls to write method
s = struct(robot_ready = False, machine_stop = False, robot_alarm = False)
s.robot_ready = True
cnc_command.write(s)

clear()

Method sets all memory managed by handle to zero.

Can only be called on the write handle.

close()

Closes handle object, and frees memory associated. It's recommended to close handles if they are used only once in a program. If handle is used repeatedly then it's recommended to keep it open over the lifespan of the program.

The same handle can not be opened again, new handle has to be created.

Bug Fixes

PolyScope GUI

The ampere value for the "IO Current" field in the Readings panel on the Log tab is now shown as a decimal number instead of a whole number
Fixed an issue where programs were slow to start, if the program contained Pallet (Palletizing)?nodes
Fixed issue on UR20 robots using a setup with an external 3-Position Enabling (3PE) Device where the Automove screen would show illustrations and text referring to the UR Teach Pendant with built-in 3PE functionality

Controller

Introduced the RTDE channel "collision_detection_ratio" which publishes a non-negative double precision floating point value which can be used to monitor how close the robot is to triggering a C157 or C158 "collision detected" protective stop. A protective stop is triggered if the value is ever equal to or exceeds 1.0. The channel is very similar to the existing RTDE channel "joint_position_deviation_ratio" which does the same for the C153 and C159 "joint position deviation" protective stops.
Fixed issue where empty string variables were incorrectly evaluated as True; now empty strings correctly evaluate as False, ensuring accurate boolean logic in conditional statements.
?Fixed issue where a robot with IMMI attached would fault the first time the robot arm was powered on after a reboot of the controlbox.
Fixed an issue where the get_inverse_kin_has_solution() function where it would incorrectly report that the solution had not been found after two or more calls with the same argument.
Fixed a corner case with movec in "fixed" mode where the TCP could rotate in the opposite direction of the required rotation to maintained the "fixed' orientation constraint.
Fixed situations where UR20 will fail with 48V voltage drop (C740A11) or over-current (C740A15), or system reboot in very hard motions.
Fixed XML-RPC issue where program would occasionally stop with "connection reset" error while calling remove procedure. It occurs in very rare conditions when xml-rpc library internally fails reconnecting to remote server. To mitigate the issue "number_of_retries" parameter was added to rpc_factory with default value 1. Change ensures that script program will try to make one extra attempt to call remote procedure before stopping program.

URCap Software Platform

Fixed issue where an unhandled null pointer Java exception would occur, in some situations, when the user tried to undo program changes. This could occur, if the user prior to the undo action had attempted twice to insert a new URCap node as child under another URCap node with locked child sequence.
Fixed issue where a URCap would never get a callback after calling the UserInteraction.getUserDefinedRobotPosition(RobotPositionCallback2) method?to request the end user to define a position of the robot. This would occur, if?the robot was not powered on and brake released ("Robot needs to be powered ON to proceed." tooltip displayed in the PolyScope footer). The?RobotPositionCallback2.onCancel() callback function is now called, if the robot is not fully operational when the request is made.
Fixed issue where a URCap would never get a callback after calling one of the methods in the RobotMovement interface, e.g. requestUserToMoveRobot(Pose, RobotMovementCallback), to request the end user to move the robot to a given target position. This would occur, if the robot was not powered on and brake released ("Robot needs to be powered ON to proceed." tooltip displayed in the PolyScope footer). The RobotMovementCallback.onCancel() callback function is now called, if the robot is not fully operational when the request is made.

Embedded

Removed generic user fault report "Start up check : Critical error", and replaced it with more clear error reports in the specific scenarios
Fixed issue where Energy Eater power dissipation monitoring can cause system to fault if the safety control board and I/O draws more than 50W.
Fix for issue where robot would be stuck in booting if a fault occurs very early after the joints boot. Could e.g. occur if the brake solenoid cable was disconnected
