3.4.3 RUN, STOP and PAUSE status operation processing
The C Controller module has three different operation states: RUN, STOP and PAUSE.
This section explains the operation processing of the C Controller module in each
operation status.
(1) Operation processing in the RUN status
In the RUN status, output (Y) to each module and buffer memory writing are enabled
from the user program in the C Controller module.
(a) Output status when entering the RUN status
When entering the RUN status, the C Controller module may output the output
status data saved before entering the STOP status, according to the parameter
setting ("Output mode at STOP to RUN").
(2) Operation processing in the STOP status
In the STOP status, output (Y) to each module and buffer memory writing from the
user program of the C Controller module are disabled by the RUN/STOP/MODE
switch setting or the remote STOP function. (
Page 4-6, Section 4.3.1)
The C Controller module is also set in the STOP status when a stop error occurs in it.
(a) Output status when entering the STOP status
When entering the STOP status, the C Controller module saves the output status
data and clears all outputs (Y) to OFF.
(3) Operation processing in the PAUSE status
In the PAUSE status, output (Y) to each module and buffer memory writing from the
user program of the C Controller module are disabled, with the ON/OFF output data
(Y) held by the remote PAUSE function. (
Page 4-9, Section 4.3.2)
POINT
1. In any of the RUN, STOP, and PAUSE states, output (Y) operation and buffer
memory writing are executable from the <<Module monitoring>> tab of C
Controller setting utility.
2. In any of the RUN, STOP, and PAUSE states, the C Controller module
internally continues user program operation.
When changing the program processing according to the operation status of
the C Controller module, use a bus interface function (QBF_ReadStatusEx)
for programming.
