8. Modbus Register Map
This chapter provides a complete description of the Modbus register (protocol ver-
sion 6.0) for the PEM533 series to facilitate access to information. In general, the
registers are implemented as Modbus Read Only Registers (RO = read only) with
the exception of the DO control registers, which are implemented as Write Only
Registers (WO = write only).
PEM533 supports the 6-digit addressing scheme and the following Modbus func-
tions:
1. Holding register for reading values
(Read Holding Register; function code 0x03)
2. Register for setting the DO status
(Force Single Coil; function code 0x05)
3. Register for device programming
(Preset Multiple Registers; function code 0x10)
