Data Access

Introduction

The BMENOR2200H advanced RTU module supports Modbus TCP server and client features. This service is disabled by default. (It can be enabled via web if the module is in Advanced mode.) The Modbus TCP server provides diagnostic data in the module's local register. The Modbus TCP Client can access this database via the module's IP address (unit ID 100).

NOTE: For details about diagnostic information for Modbus TCP, refer to the appendix of Modbus diagnostic codes.

You can also use the RTU module service to transfer a Control Expert configuration file to the CPU over X Bus. In this case, you do not have to connect an external engineering station directly to the CPU.
