Bulk edit SIS Controller Modbus Port register mapping

This section outlines how to bulk edit DeltaV SIS Controller Modbus port registers mappings to module. There are a few conditions that must be met to bulk edit register mapping:
  • Each register_type value must be correct for the corresponding register_name. For example, register_names between R10001 and R11000 must be register_type Input status.
  • Importing more register mappings than the allowed number of registers for a particular type imports only the registers up to the maximum allowed value.
  • The register_name for Float input and Float holding register types must end with an odd number.
  • If the bulk edit file contains gaps in the register_name list (for example R1 and R3 exist in the file but R2 does not), the omitted registers are created on import but are not mapped.
Note:

Bulk edit can add or modify registers but cannot remove registers. The only way to remove registers is from the Modbus Port Properties dialog Data sets tab.

The general procedure to bulk edit is:

  1. Create and configure one register of each type to be configured.
  2. Use the Modbus_Port.fmt format specification file to export the data or create your own format specification file.
  3. Copy and edit the exported file in the bulk edit Excel template as required.
  4. Import the edited data.
