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.

| Device Control |
Reset | u16 | RW | 55203 = To Reboot | 1201 |
| Bootloader / Application | u16 | R | 0x00A – Application, 0x00B – Bootloader |
1203 | |
| Restart to Bootloader | u16 | RW | 617 = To Bootloader else = deactivate bootloader |
1204 | |
| Device Status |
Board Power Voltage | u16 | R | 105 = 10,5V | 1311 |
| Board Temperature | u16 | R | -200 = -20,0°C 250 = 25,0°C |
