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–2 lists 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.

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.
