Hello Plc engineer,
It's true that the manual doesn't tell you much regarding what to do in hardware configuration however it is still very important to understand chapter 10 very well. Redundant I/Os require, 1- Hardware configuration. To understand what you have to do in details you will find yourself obliged to go through one of PCS7 documents which is Configuration of Redundant I/O Modules. Just read what is related to hardware configuration and leave the programming part as you will be using STEP7. 2- Software blocks. The software blocks are briefly explained in chapter 10 however and for more understanding you will have to press F1 on each block of the RED_IO library in STEP7. For a sample program for both HW and SW, check this thread. Best regards. H-H |
