Hello all,
I am relative new to PLC's.
I am looking to read 4 Modbus registers on a slave device via RS485 and then validate the data. Can a PLC be used for this?
Register 1, Asset ID
Read 'asset ID' and check against lookup table, if 'asset ID' is in the table move on.
Register 2, Location
Read 'Location' and check against lookup table, if 'Location' is in the table move on.
Register 3, Load Date/Time
Read 'Dispatch Date/Time' against current date/time and ensure 4 hours has not passed.
Register 4, Loaded Product
Read 'Loaded Product' and ensure it is equal to 'XYZ'.
If all data in the 4 registers is validated then switch control output.
Any thoughts are appreciated.
