PeterFukt Posted March 1, 2018 Report Share Posted March 1, 2018 Hello, I have made programs for SAMBA PLC SM35-J-T20 and TA22 with Modbus configuration. In Com init help, it tell me to select RS232 or RS485. But the field is grayed out on RS232 and I can't select RS485. If I remember right, I could select RS485 when I did the program for the first time, but when I chech the Com Init settings, they all say RS232 and not RS485. Doesn't it matter if it say RS232? I had to change it to RS485 in Info mode to get communication to work, but if I loose power, it returns to RS232. Quote Link to comment Share on other sites More sharing options...
