24V load circuit monitoring with SITOP PSE200U single-channel signaling and SIMATIC S7 CPUs
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.
