Modbus Registers
Below is a list of available device MODBUS registers. The same register numbers are also used by the MIOS-2 protocol.
Modbus Read / Write (0x17) Function
METEL IO modules have implemented 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) Write 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 writing and reading 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
