Hello to everyone. Can someone help me? How to connecting peripheral port Omron PLC CQM1H-CPU21 with a PC at a distance of 100 meters. Now I have a cable connection CS1W-226 but it's a small distance. Host Link Port is busy with my NT21 panel Thank in advance.

Too far for serial. You may get away with RS232/422 converters - 4 wire not 2.
