TEST
Function: You can test your program without enabling outputs.
Response: All outputs are disabled. Program instructions are executed.
RUN
Function: Your program is continuously being scanned and executed.
Response: Programmed instructions control the outputs. Program changes can
not be made.
RUN PROG (remote mode selection)
Function: Lets you select the desired mode without having to turn the
keyswitch.
Advantage: When the keyswitch is in the RUN/PROG position, you can enter
instructions from the industrial terminal that will place the series B processor
into any one of the remote modes of operation:
Remote Program - identical to the switch-selected program mode. The
program scan and I/O scan will be halted. All outputs are disabled. Going
into this mode from remote run/program will reset an I/O fault and clear a
memory parity error.
Remote Test - identical to the switch-selected test mode. The program
instructions are executed, but all outputs are disabled.
Remote Run/Program - identical to the switch-selected run mode. Whenever
the keyswitch is turned to the RUN/PROG position the processor
automatically enters this mode.
On-Line Data Change - similar to the run mode, except that you can change
data table values associated with instructions.
On-Line Programming - allows you to make program changes while the
program is running and controlling the outputs.
