=== 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 the 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 ===
Device ID: 1 
Baudrate: 115 200 
Parity: None 
Data bits: 8 
Stop bits: 1
