NT21 - touch panel question

[pszczepan 2]

I use CPM1A connected to NT21 via CIF01. NT21 has two RS232 ports. I connected NT with PC and at the same time I established connection with Support Tool for NT. My question is if I can monitor PC (CPM1A) via RS232 on the touch panel NT. Thanks Pawel

I'm sorry the answer is no. Data Transfer Using SPMA (Single Port Multi Access). Avalible only in NS touch screen connected to CJ/CS PLC by HIGH SPEED 1:N NT LINK & the computer connected to NS by controller link or ethernet. see spma.jpg

It is mean that if I want to monitor PC via RS232 I have to disconnect cable from NT21 and make connection via another cable to CX Programmer. Can I make it without switching off CPM1A or I should switch off OMRON equipment to avoid internal demage.

You can plug and unplug the cable durring operation

You may consider upgrading to CPM2A, the has two com ports built in.
