I would like a piece of advice about how I can stop the code execution in FPGA in etherCAT chassis. I work on a piece of code where I start the VI in a RT computer and the FPGA produce PWM puses with a difital module. However, stopping the main VI, the FPGA is still working giving pulses with the NI module. I'm trying to send a stop command from the main VI to the FPGA without success. Is there any specific type of command to communicate with the FPGA in etherCat ?
Note that the initial code is not made by me, so I don't have fully control of it.
