We have a Unistream HMi which is connected to a remote Modbus Slave (Prosoft PLX31 Modbus Gateway) I need to read the bits from particular words which hold the status of sensors mapped to the Gateway tables. On the holding register entry page, it does not allow for just reading 1 bit of a word. Is there a work-around or some example of plc logic that will take that register and read the bits into a bit-array? Thank you,
I'm working on understanding the RLO to Bit function block, personal knowledge more so than application use. I think I have a fairly decent idea of the applications of it but I'd like to get an idea of an actual use on it. In my head it seems to be an unnecessary abstraction of other combinations of function blocks. Any feedback or application examples would be immensely helpful. Thank you!
