Issuing Commands

To issue commands using the command interface, follow these general steps:

1.Write the related parameter(s) to the command parameter registers 8001–15.

2.Write the command code to command interface register 8000.

If no parameters are associated with the command, then you need only to write the command code to register 8000. Table C–2lists the command codes that can be written to the command interface into register 8000. Some commands have an associated register where you write parameters for that command. For example, when you write the parameter 9999 to register 8001 and issue command code 3351, all relays will be energized if they are set up for external control.

Table C–2: Command Codes

	8004	Hour
			Hour (Military time, for example 14 = 2:00pm)
	8005	Minute
			Minute (1–59)
	8006	Second
			Second (1–59)
1410	None	None	Disables the revenue security switch
1411	None	None	Enables the revenue security switch

3340	8001	Relay Output Number ➀	Releases specified relay from override control.
3341	8001	Relay Output Number ➀	Places specified relay under override control.
3350	8001	9999	De-energizes all relays.
3351	8001	9999	Energizes all relays.
3361	8001	Relay Output Number ➀	Resets operation counter for specified relay.
3362	8001	Relay Output Number ➀	Resets the turn-on time for specified relay.
3363	8001	None	Resets the operation counter for all relays.
3364	8001	None	Resets the turn-on time for all relays.
3365	8001	Input Number ➀	Resets the operation counter for specified
			input.
3366	8001	Input Number ➀	Resets turn-on time for specified input.
3367	8001	None	Resets the operation counter for all inputs.
3368	8001	None	Resets turn-on time for all inputs.
3369	8001	None	Resets all counters and timers for all I/Os.
3370	8001	Analog Output Number ➀	Disables specified analog output.
3371	8001	Analog Output Number ➀	Enables specified analog output.
3380	8001	9999	Disables all analog outputs.
3381	8002	9999	Enables all analog outputs.

➀ You must write to register 8001 the number that identifies which output you would like to use. To determine the identifying number, refer to“I/O Point Numbers” on page 86 for instructions.

➁ Data buffer location (register 8019) is the pointer to the first register where data will be stored. By default, return data begins at register 8020, although you can use any of the registers from 8020–8149. Take care when assigning pointers. Values may be corrupted if two commands are using the same register.

Refer to “Register List Access” on page 79 for instructions on accessing the complete register list.
