Hello Youcef; You are working with a S7-300 CPU, in Simatic Manager (Step 7 v5.x)? In that case the CMP<>R instruction is not valid, see this extract from the S7-300 Instruction List manual: Change the instruction for <>R. https://support.industry.siemens.com/cs/ww/en/view/31977679/28405741707 Hope this helps, Daniel Chartier |
