Bulk Modbus Tags Adding

Ignition
1

I’m working with MODBUS TCP to communicate with different PLC that contains approximately 30,000 registers. I need to bring these registers into Ignition as tags, but I’m running into a couple of challenges:

  • The registers are not arranged in a consistent order.

  • Some registers represent single holding values.

  • Others require bit-level mapping.

What would be the most effective approach to structure and manage these registers in Ignition, considering these constraints?

I would use my spreadsheet import tool from the Exchange. Where you have any patterns of multiple registers, make UDTs that have a start offset parameter.
