Common Service Input Status
If any bit below is 1 then the input is ON.
Bit 0: INH (Inhibit input – NOT used in Omni30)
Bit 1: TST (Lamp Test input)
Bit 2: ACK (Accept/Acknowledge input)
Bit 3: SIL (Silence input – NOT used in Omni30)
Bit 4: RES (Reset input)
Bit 5: FS (Flash Sync input - this bit is READ ONLY)
Bit 6: FO (First Out input - this bit is READ ONLY)
Bits 7-15: Reserved
NOTE:
The SIL, ACK and RES bits are automatically reset to 0 after 3 seconds when set by the Modbus
Master. All other bits must be reset by the Modbus Master.
When using Modbus Coil writes (Modbus Function 5) the coil mapping is as follows:
