Table Of Tmd Registers - ABB TMD-T4 Instruction Manual

TABLE OF TMD REGISTERS

This table is referred to the TMD-T4 device with 4 input channels and TMD-T8 device with 8 input channels.
Decimal value is calculated as follow
Dec. Value = (MSB Byte *256) + LSB Byte
Instantaneous temperature register (read only)
- TMD-T8: from 0x0258 (CH1) to 0x25F (CH8), 8 register 2-byte wide, integer value of Celsius degree
- TMD-T4: from 0x0258 (CH1) to 0x25B (CH4), 4 register 2-byte wide, integer value of Celsius degree
-
NOTE: These register return also the coded status of the probe input; a valid value of temperature is added the
integer 0x0019; follow explaining example
- Value 0x0000 Input is shorted, display of that channel mean
- Value 0x0001 Input is open; display of that channel mean
- Value 0x0019 Input is right connect to PT100; measured temperature is 0 °C
Max temperature register (read only)
- TMD-T8: from 0x0260 (CH1) to 0x267 (CH8), 8 register 2-byte wide, integer value of Celsius degree
- TMD-T4: from 0x0260 (CH1) to 0x263 (CH4), 4 register 2-byte wide, integer value of Celsius degree
Instantaneous absolute temperature register (read only)
- TMD-T8: from 0x0280 (CH1) to 0x0287 (CH8), 8 register 2-byte wide, integer value of Celsius degree
- TMD-T4: from 0x0280 (CH1) to 0x0283 (CH4), 4 register 2-byte wide, integer value of Celsius degree
NOTE: These registers return binary values from -30 (0xFFE2) to +200(0x00C8)
Max absolute temperature setting register (read only)
- TMD-T8: from 0x0288 (CH1) to 0x028F (CH8), 8 register 2-byte wide, integer value of Celsius degree

- TMD-T4: from 0x0310 (CH1) to 0x0313 (CH4), 4 register 2-byte wide, integer value of Celsius degree
State (diagnostic) of the input channels (read only)
- TMD-T8: from 0x0290 (CH1) to 0x0297 (CH8), 8 register 2-byte wide, integer value of the state of channel
- TMD-T4: from 0x0290 (CH1) to 0x0293 (CH4), 4 register 2-byte wide, integer value of the state of channel
- Value 0x0000 Input is right connect
- Value 0x0001 Input is shorted, display of that channel mean
Value 0x0002 Input is open; display of that channel mean
- Value 0x0003 Input is failure display of that channel mean
Fan control setting register (read / write)
