Both communications ports of CPU51 (omron cqm1h) are used in the system. peripheral port is connected to programmable terminal (omron nt30) and rs232 port is connected to one more cpu51 (omron cqm1h).
At present the red ERR/ALM indicator of first cpu lights. I could use CX programmer 2.1 but I don't know how to do it (where to connect and what cable). Is it possible to delete this fatal error from cpu using cx programmer or to know what kind of error I have at least?
Thanks for advance.
