Modbus item naming

The Modbus-family controllers store data in the Registers. The MBTCP Communication Driver supports item names that are consistent with the point naming conventions used by the Modicon PLCs.

The following item naming conventions are described in this section:

• Register-Number Item Names

• Item Names Using the Modicon PLC Register Addresses

• Item Names Using the Absolute Naming Convention

• Item Names Using the Modulo-10000 Naming Convention

• Modulo-10000 Items, BCD Register Type, and Concept Data Structures

  Note: The tag-name length with SuiteLink is limited to 32 characters.
