Table 3-10 Read Time Response Message
4) Control Relay (Function Code 05)
Query
The message forces a single Relay either on or off. Any Relay that exists
within the Acuvim II can be forced to be either status (on or off). The
address of Relay starts at 0000H, and Acuvim II has eight Relay.
The data value FF00H will set the Relay on and the value 0000H will turn
it off; all other values are illegal and will not affect that relay.
The example below is a request to Acuvim II address 1 to turn on Relay 1.
