Title: DataSubscriber2 to expose changing modbus register
Post by: MrPike on June 14, 2018, 04:46:32 PM

Archie,  i need to examine about a 100 registers of a controller via ModbusTCP and I am trying to determine which one has changed without knowing in advance. is there a way for the DS2 to expose which register value(or index)has changed without having to write 100 ElseIf statements?  Maybe one code snippet that can put the value in a msgbox. Thanks.
