Modbus Gateway Register Map
The SignalFire Modbus Gateway by default is assigned Modbus ID number 247.
Only the
Gateway status/configuration and remapped registers are read at this address.
All
remote node registers are read from the Modbus ID and register address of the remote node
unless Modbus register remapping is used. If the gateway has a large total number of registers
approaching 4700, register 2008 should be monitored to ensure that free registers are available before adding
a new node.
Coils
Read coils with Modbus opcode 0x01 (Read Coil). Write coils with Modbus opcode 0x05 (Write Single Coil) or
0x15 (Write Multiple Coils).
