About the 57C429

The 57C429 is a Reliance Electric created R-NET Processor Module. There is a good probability that this device was sold by Asea Brown Boveri or Baldor Reliance under their product lines depending on what year it was being manufactured. The original companies that produced the 57C429 are no longer offering support for it. This item may be hard to locate, but AX Control does try to keep it in stock.

The 57C429 was created to be part of the AutoMate PLC control system and is a Single-Board Interface R-NET Module. It had the ability to grant peer-to-peer communication between an AutoMate and AutoMax system. This system is advantageous because it allows for the possibility that a node can drop offline and the system will still be allowed to communicate. If you use an RG-11U cable, you can connect a maximum of 32 AutoMate controllers to the R-NET.  This configuration is a synchronous baseband coax cable network that has a multidrop networking system.

This entire system can be attached to an AutoMate storage rack. You can actually have more than one 57C429s plugged in at a time. When you attach them to the rack, you can have the option of running various network lines to each of the modules. Depending on what your actual system needs are, you can run these modules on the same network line or on a completely separate system.

The 57C429 has a faceplate that has several features on it. It has 8 LED lights that are labeled READ, XMIT, RECV, COM OK, and four that are labeled COM ER. This module also has a spot to plug in a coax cable and two dials that are labeled MODE NO.
