PROFACE HMI

[SHIV121 1]

HELLO ALL, 

I HAVE AN PROFACE HMI GC4401W, I WANT TO COMMUNICATE THAT PROFACE HMI WITH THE TWO 24CHANNEL SLVAE DEVICES. FOR COMMUNICATION BETWEEN MY HMI AND THAT SLAVE DEVICE, I HAVE NOT ANY CABLE. I KNOW THE PROFACE HMIs COM2 SUPPORTS THE RS485 COMMUNICATION. CAN ANYONE TELL ME THE 2 WIRE CONNECTION FOR COM2(PROFACE) TO THE SLAVE DEVICE...

PLZ.....HELP ME ...IF ANYONE KNOW ABOUT THIS.

You need to be more specific about what it is talking to.  24 channel slave device does not tell us what type of device you are connecting to.

I don't know Proface, but I would expect there to be help in the manuals on the COM port pin numbers.
