I have a question about the module GRV-CSERI-4. Everytime I am changing the category of rs485 there are error that is pop up. “Server offline-data may be stale” how can I fix this. And when i am running it on pac control and changing it there using i/o points, It is changed in pac control but in epic still not. Can you help me on this please. I just need to communicate the power meter using grv cseri 4.
Here is my setup in communication handle
@Feeder3(name on my I/o unit) :baud=9600,parity=n,data=8,stop=1.
I believe this is correct but trying to open tge communication handle there is error - 87(open error) so I believe it is not communicating. And my wiring is also correct i am using half duplex rs 485. I’L put the positive in no. 1 slot and the negative is no. 2 slot in channel 0
And if you will check in groov epic through serial devices it is appeared there no usb serial converter or GRV CSERi-4 detected even I already installed the GRV CSeRI-4 in epic!please see picture
