S7A driver shows same values for different inputs in data monitor

1 post in this topic

Hello!
I am beginner in PLC world, also in SIEMENS PLCs. I managed communication over private network. Now I have a problem that I get same values on all inputs. Picture below shows my configuration of driver and data monitor. First picture shows values when input I0.0 is in state 0. Second picture shows values when input I0.0 is in state 1. Physically on PLC only input I0.0 is forced to 1, input I0.1 stays 0. But data monitor shows both inputs as state 1. Where is problem? Is problem in PLC program, TIA portal? I saw some guys using DataBlocks but I am not skilled enough to use it. Third picture shows simple PLC program on my PLC. Please help. Thanks in advance!
