6. Overview Modbus registers (RCMS150-01 only)
This chapter provides a complete description of the Modbus registers to facilitate ac-
cess to information.
RCMS150-01 supports the following Modbus functions:
1. Register for reading values
(Read Holding Register; function code 0x03)
2. Register for writing values
(Write Multiple Registers; function code 0x10)
The device exchanges the data in big-endian order. The counting method of the regis-
ters is 0-based. To check these properties, the UINT32 register 0 can be read and com-
pared with the target value 0x12345678.
