Hello, I am trying to change tariff on a PAC4200 using Digital Input 0 (DI0). I have a cable running directly from a PLC output to the device. I can see the state of the DI change depending on the presence or absence of 24V, however I can't seem to be able to make the PAC to change the tariff it is using. Digital Input State off Sentron PAC Screen here you can see the state is off Digital Input State on PAC Screen here you can see it's on In the two following pictures you can see what is happening on plc side. It's quite simple, I am using a testing merker to change the state of the output Q0.5 PLC side off PLC side on Said output is connected to DI0 on the PAC4200 and that's what causing the change of state of DI0 on PAC's side. My expectation from this was to see the PAC switching from one tariff to the other, like it says on the manual, but I had no luck so far. I wonder what I am missing. Edit: I noticed that in the event tab on the sentron the change of tariff is logged, but it seems like a ghost event, the sentron keeps adding the consumption on the first tariff. However, I also noticed that if I leave DI0 at true for some minutes, the tariff actually switches. I wonder why there is a delay. AttachmentFiles.zip (851 Downloads) |
