Hi @matthewd92
is there any command to use start, stop and pause the programs in UR through modbus.
in ur, only config inputs i can configure start, pause and stop but configurable inputs cannot be write in modbus.
I can use dashboard server, but still i want to know whether i can use modbus or not.

But how can i write values to input from gui. For digital output such options are not available.
I use writesingleregister(138,1) to trigger output. How to write for inputs.
I tried by using modbus signals as you suggested but couldn't trigger the input
Does that make sense? The robot is not intended to trigger inputs, only outputs. Inputs are intended to be signals sent from other devices to the robot, so the robot is listening for the event to occur. Outputs are the robots way of communicating out to other equipment and so that equipment is listening for the event to occur.
I totally agree with your point.
But modbus is not only for attach additional input and output but also we can do access input and outputs by pc program using any programming languages such as python or java or any over ethernet without hardwiring of input and output as well.
Am using C# and i wanted to start and stop program using modbus. Is that possible???
If you are doing C# though, why not do RTDE? It's a much more robust protocol that UR provides as an interface to the robot, not only can you write registers from there you can also read the full state of the robot giving you the possibility to control more and know more about the robot.
