I bought two digital output modules (6ES7 222-1HH32-0XB0) and one digital input/output(6ES7 223-1PL32-0XB0), but when LED is ON, there is not any voltage at output. I did: 1. I checked the relay resistance between pin 3L and DQb.0, and it doesn't show short when LED is ON. 2.then I Forced a bit to DQb.0, but there is not any voltage. CPU(s7-1214c) and digital input module are ok and there is a resistance, but digital output modules have problem and there is not any resistance. at end, CPU was made in Germany and digital modules was made in china.

Thanks everyone! I was thinking, i should connect 3L and DQ only but now i connect 24vdc from CPU to module and all of module's outputs work well. I must see system manual (pdf) more carefully. i attached image that has arrow of 24 vdc. Attachmentimage2.rar (293 Downloads) |
