I have a Micro 311 set up for RTU serial and I want to use it for ASCII serial, I am using FasTrak Softworks for Modicon programming software, I have not successfully been able to change it over, manuals are scarce online, from the info I did find I am confused if comm port 1 will work for ASCII of if I need to connect to I?O exp link and us RS-485 for ASCII, I know this port is for connecting other PLCs normally, help from any experts would be greatly appreciated, thank you.
