FORCE SINGLE COIL (FUNCTION CODE 05)
This message forces a single coil either On of OFF. Any coil that exists within the controller can be forced
to either state, (ON or OFF). Coils are numbered from zero (i.e. coil 1 is address 0000, coil 2 is address
0001, etc.). The data value 65,280, (FF00 HEX) will set the coil ON and the value zero will turn it off. All
other values are illegal and will not effect the coil. The use of slave address 00, (Broadcast mode), will
force all attached slaves to modify the desired coil.
The example below requests slave number 17 to turn coil number 0173 ON.
