Imported (Write Single) Modbus Registers - SKF Multilog On-Line System IMx-M User Manual

Imported (Write Single) Modbus Registers

An IMx-M protection part Modbus slave has registers that can be written from the
Modbus master.
Notes on Implementation

Modbus registers translate according to the table below.

The write single function code is 0x06.

The read function code is 0x03 (for registers with read/write access).

Definition
1 = disarm
0 = arm
MSB = Ch 16, LSB = Ch 1
1 = disarm
0 = arm
1 = enable slot TM
0 = disable slot TM
MSB = Ch 16, LSB = Ch 1
1 = TM active
0 = TM not active
1 = reset latching alarms / relays
0 = do nothing
Bit 7 = Ch 8, LSB (Bit 0) = Ch 1
1 = disarm
0 = arm
1 = reset digital peak
0 = do nothing
1 = disarm
0 = arm
Bits 7 to 0 (latched sensor faults)
 MSB (bit 7) = Ch 15 and 16,
 LSB (bit 0) = Ch 1 and 2
Bits 15 to 8 (latched relays)
 MSB (bit 15) = Relay 29 to 32,
 LSB (bit 8) = Relay 1 to 4
1 = reset latching faults / relays
0 = do nothing
