ControlLogix Modem Communications


Thread Starter


I am looking for information on setting up a modem to communicate with an AB ControlLogix PLC. Can anyone help with cable info, PLC settings, and Modem settings. Thanks Richard McSwain Control Source

I´ve done the communication with an SLC 500 using a CDPD Modem, I guess the configuration using a controllogix is pretty similar. You will need to configure the dirver you are using in RSLinx to use a modem dialer, you will need the initialize, dial, command mode, dial suffix and hang up string for the modem you are using and configure them in the driver. You will also need to configure the controllogix communications channel at the same baud rate as the modem.
