Modbus Registers

Below is a list of available MODBUS registers. The same register numbers are also used by the MIOS-2 protocol.

Modbus Read / Write (0x17) Function

METEL IO modules have implemented the MODBUS function (0x17) Read/Write of Multiple registers. Typically it is required to have two separate requests (and responses) for:

1. Writing of outputs via MODBUS function (0x16) Writing Multiple Registers

2. Reading of inputs via MODBUS function (0x03) Read Holding Registers


This requires a total of 4 frames to be sent over MODBUS. If using 0x17 function only one request is needed for the reading and writing of outputs. This requires a total of 2 frames to be sent over MODBUS.


Default Settings of Communication

Baudrate: 115 200
Parity: None
Data bits: 8
Stop bits: 1


BUS 0 - is used for internal communication within one IPLOG-GAMA device between main board, IO module and IF module.
BUS 1,2 - are the external buses of the IF module (IF-01, IF-05...).
