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

IF#01 Product Type u8[3] R 1022-24
IF#01 Serial Number u32 R 1025-26
IF#01 PCB Version u32 R 1027-28
IF#01 PCB Revision u16 R 1029
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 		1321

Note: To activate the bootloader, it is necessary to write a value 617 in to the registry with offset 1204 and restart the device.
