63230-300-212 AppendixB—Using the Command Interface

April 2001 Overviewof the Command Interface

183

Toissue commands using the command interface,follow these general

steps:

1. W rite therelated parameter(s) to the command parameter registers

8001–15.

2. W rite thecommand code to command interface register 8000.

If no parametersare associated with the command, then you need only to

write the command code to register8000. Table B–2liststhecommand

codesthat can be written to the command interface into register 8000.Some

commandshave an associated registers whereyou write parameters for that

command.For example, when youwri tethe parameter 9999 to register 8001

and issuecommand code 3351, all relays will be energizedif they are set up

for externalcontrol.

Relay Outputs

3310 8001 R elay Output Number Configures relayfor external control.

3311 8001 R elay Output Number Config ures relay for intern al control.

3320 8001 R elay Output Number De-e nergizes designated relay.

3321 8001 R elay Output Number Energizes designatedrelay.

3330 8001 R elay Output Number Releases specifiedrelay from latched condition.

3340 8001 R elay Output Number Relea ses specified relay from overr ide control.

3341 8001 R elay Output Number Places specified relayunder overridecontrol.

3350 8001 9999 De-energizesall relays.

3351 8001 9999 Energizesall relays.

3361 8001 R elay Output Number Reset s operation counter for specified relay.

3362 8001 R elay Output Number Resets the tu rn-on time for specified relay.

3363 8001 N one Resets the operati on counter for all relays.

3364 8001 N one Resets the turn-on time for all r elays.

3365 8001 InputNumber Reset st he operation counter for specified i nput.

3366 8001 InputNumber Reset s turn-on time for sp ecified input.

3367 8001 N one Resets the operation counter for all inputs.

Youmust wri te to register 8001 the number that id entifies which output you would li ke to use. Todeter mine the identifying number, refer to

“I/O Point Numbers”on page 186 for instru ctions.

Data buffer location (regist er 8019) is the pointer to the first reg ister where data will be stored . By default, return data begin s at register 8020,

although you can use any of the reg isters from 8020–8149.

Takeca re when assigning pointers. Values m ayb ec orrupted if two commands

are usingthe same register.
