Posted 28 Mar 2020 Hello guys, I am very new at this. I am trying to make a Schneider PLC (TM251MESE) to send some serial commands (485) to a integrated stepper motor from Automation Direct (STR-MTRD-17030RE, but I am lost. The driver has been program to receive the SCL commands. But not quite sure how to send those from the plc. Im using SoMachine V 4.2 Have any of you done anything similar? Any example will be greatly appreciated. Thanks Share this post Link to post Share on other sites
