I have to send data (example below ) to a programmable power supply, from a CJ1M PLC serial port to an rs232 port on the Psu.
I am new to this level of programming and i am having problems understanding some of the commands.
I want to be able to set the voltage from the ladder.
Can someone spare the time to walk me through it??
Best regards.
