3.4.3 RUN,STOP and PAUSE status operation processing
The C Controller module has three different operation statuses: RUN, STOP and PAUSE.
This section explains the operation processing of the C Controller module in each
operation status.
(1) Operation processing in RUN status
In the RUN status, output (Y) to each module and writing to buffer memory are
enabled from the user program in the C Controller module.
(a) Output status when entering RUN status
When entering a RUN status, the C Controller module outputs the output status
data saved when it entered a STOP status according to the parameter setting
("Output mode at STOP to RUN").
(2) Operation processing in STOP status
In the STOP status, output (Y) to each module and writing to buffer memory are
disabled from the user program of the C Controller module by the RUN/STOP/MODE
switch or remote STOP function (
Section 4.5.1).
The C Controller module is also put in the STOP status when a stop error occurs in it.
(a) Output status when entering STOP status
When entering a STOP status, the C Controller module saves the output status
data and clears all outputs (Y) to OFF.
(3) Operation processing in PAUSE status
In the PAUSE status, output (Y) to each module and writing to buffer memory are
disabled from the user program of the C Controller module, with the ON/OFF output
data (Y) held by the remote PAUSE function ( Section 4.5.2).
POINT
1. In any of the RUN, STOP and PAUSE statuses, the C Controller module can
perform the output (Y) operation and writing to buffer memory to from the
<<Module monitor>> tab of the C Controller setting utility.
2. In any of the RUN, STOP and PAUSE statuses, the C Controller module
continues user program operation inside it.
When changing the program processing according to the operation status of
the C Controller module, use the bus interface function (QBF_ReadStatusEx
function) for programming.
