table as Figure 2.13. The "Remote" item in the mapping table represents the Register address
of the Modbus RTU device; the "MDC-211-ZT" item represents the corresponding Internal
Register address. The users can access Internal Register address in the "MDC-211-ZT" item
via the Modbus protocol to control the entity Modbus RTU device.
