Hello guys, I’m having trouble with the last module in the rack (10 DO safety). The DO safety module is not ok. The SF LED from the module and the PLC remained on (red) and the SAFE LED from the module remained off. I have configured an example in STEP 7 V5.4 with only 1 output (channel A/B 80.3/Q81.0) connected to a coil contactor (24 Vdc) and 1 input (channel A/B) connected to an E-Stop button (I40.0). Order No./ Description Component Version Rack: 0
-------- Please, I need help, what is the problem ?? the module (hardware) ? the configuration ? what could be ?

Hi Berg, Please consider that you might see older screens... and didn't see what I see, most of the time this trouble happens when you first had placed the older module in the hardwareconfiguration. Do you also know that the F-DO10 is switching two times in the Plus ? The newer F-DO8 switches in the Plus and in the Minus and is preferable to use. Look also in the newest handbook for the S7-300 Failsafe moduls: Automation System S7-300 Fail-Safe Signal Modules |
