Okay here we go. I am new to this and I need to know the easiest method to mate an Micrologix 1100 to and Automation Direct with RS232. I have a Lantonix converter. But is there an easier way?
Just add a small ethernet switch, then you can connect the PLC, HMI and your programing PC all to the switch using CAT5 cable with RJ45 connectors.
(Standard ethernet patch cables)
This is the easiest way. I am not a big fan of converter they are not robust specially cheaper versions. So get the hmi with ethernet port or use 232 cable.
But you must try lantronix too shouldn't be too hard since you already have it.
Find another cable at automation which one end is DB9 and connect to lantronix.
