Hello. I have problem with encoder card FM350-2 COUNTER (6ES7 350-2AH01-AE0). I installed “Configuration Software for FM 350-2 Counter Module” set parameters, use FCs and UDT from library, set SW_GATE, but I cannot read values from encoder. In HW config double click to FM350-2 card Debug/Commissionig I can see correct value in Other Test box. But in DB1.ACT_CNTV0 I see still zero value. After that I used example project from “Configuration Software for FM 350-2 Counter Module”. It was working, but after some time the value was not changing, so the same situation as before. I use three encoders, so I can use direct address PIW, but In feature I will connect another two encoders, so I cannot read five encoders by direct address. I don’t know what I’m doing badly. Any idea where can be problem. |

Hello Is your FM350-2 on the main rack or at a remote I/O point? I have seen this problem when it isnt on the main rack and at a remote I/O location via profinet.You have to put a siemens protected block in called CNT2RDPN and then call it in your FM350-2 block. I have attached a screen shot of my example. Hope this helps!
