The CPB 021 expands the broad spectrum of the C-DIAS products from SIGMATEK with a Profibus DP slave gateway. The module supports a galvanically isolated Profibus slave and thereby offers various possibilities for the coupling of automation devices with Profibus.
With this gateway, data can be efficiently exchanged between the C-DIAS control system and decentral field components such as I/Os, drives, HMIs or valves. The on-board processor manages the complete Profibus traffic and thereby completely frees the CPU from processing the Profibus protocols. The communication with the PLC takes place over a 64-kbyte Dual-Port RAM. Five diagnostic LEDs indicate the actual status of the module. Transfer rates from 9.6 kbits/s to 12 Mbits/s can be set.
