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
Device ID: 1
Baudrate: 115 200
Parity: None
Data bits: 8
Stop bits: 1
Note: The MODBUS address is the same as the address of the main device of which the IF module is part.
| Subject | Channel | Type | R/W | Value | Offset | |
|---|---|---|---|---|---|---|
| IF-11 States of Inputs |
Balanced Input 1 (bin) | DI#33 | bit | R | 0 = inactive 1 = active |
3033 |
| Balanced Input 2 (bin) | DI#34 | bit | R | 3034 | ||
| Balanced Input 1 | AI#33 | u16 | R | 1000 = 1000Ω 0 = 0Ω |
5033 | |
| Balanced Input 2 | AI#34 | u16 | R | 5034 | ||
| Inputs | DI#33 - DI#48 | u16 | R | 0x0000 - 0x0003 | ||
