Reliance Automax. In stock ships today. R-Net Processor module. 57429. 57C429. 57C429A. 57C429B. The Automax R-Net Processor module (M/N 57C429) provides the means for an Automax/DCS 5000 rack to communicate over the R-Net industrial network. The R-Net network allows Automate Processors, Automax/DCS 5000 Processors, and other devices to communicate with each other to create a distributed control or centralized data-gathering system. The Automax R-Net Processor can support up to four Automax/DCS 5000 Processors in one rack. R-Net views the rack as one node consisting of an Automate Processor. Each Automax R-Net Processor module contains a 16K byte dual-port memory for storing the data that is transmitted over the network. The dual-port memory contain an image modeled on a subset of Automate registers. Data received from the network is placed into the Automate image area by defining the destination as an Automate address. Date is transmitted from the Automate image area over the network using a subset of Automate communications commands. The dual-port memory can be accessed by the on-board CPU as well as over the backplane bus by any Processor in the rack through application programs.
