PLC Compatibility

The PLC Access® Modem is a remote access device enabling connections to different model Programmable Logic Controllers (PLC) used in various industries. The PLC Access® Modem enables a remote technician to connect to a machine's PLC through the programming port and an analog phone line. This connection allows transfer of the ladder logic program to, or from, the remote location. Modification, correction, or troubleshooting of the ladder logic can be accomplished remotely, and the revised ladder logic program can be transferred back to the PLC.

This process is accomplished by the RS-232 port provided on the modem, that will allow the user to directly connect to the desired PLC via the manufacturers programming cable.
