24V load circuit monitoring with SITOP PSE200U single-channel signaling and SIMATIC S7 CPUs
Concerne le/les produits(s)
The signal at the state output (S) of the SITOP PSE200U module provides serially encoded information on the state of the load circuits connected to the outputs OUT 1 thru OUT 4 of the SITOP PSE200U module. A SIMATIC S7 CPU shall be used to acquire and monitor the status of the load circuits.
The present document includes a collection of block libraries and library descriptions for SIMATIC S7-300/S7-400 and SIMATIC S7-1200/S7-1500. The library blocks are used to read and evaluated the signal of the state output (S) via a digital input at the S7 CPU. You may display this information e.g. as a message on an operator panel, as a potential application. The needed digital inputs and outputs can be located in a Distributed I/O (e. g. ET 200SP).
The library blocks for S7-300/S7-400 can be used in an ET 200S IM 151-8(F) PN/DP CPU and ET 200pro IM 154-8(F/FX) PN/DP CPU. The library blocks for S7-1200/S7-1500 can be used in an ET 200SP CPU.
The figure below shows the solution in the form of a graph.
