Preventa™ safety PLCs
Modular, XPSMF60
Rack, power supply and CPU
Line control is a means of short-circuit and line break monitoring.
Using line control outputs enables SIL 3 (EN/IEC 61508) and category 4 (EN 954-1)
safety to be achieved. The line control outputs send a high signal with a very short
low signal, thus enabling a wiring anomaly (short-circuit, line break) to be seen at the
inputs of the safety PLCs.
The digital outputs 1 to 16 of card XPSMFDIO241601 are connected to the digital
inputs of the same card or to the digital inputs of card XPSMFDI3201.
(1) FB1 not used.
