The display element on the programming console screen shown below com-
prises the mode selection keys, which change the operation mode of the PC,
and the mode lock key, which prevents unintended mode changes.
Mode selection keys
Mode lock key
The RUN, MONITOR, and PROGRAM mode selection key elements are touch
switches and pressing them causes the PC operation mode to change (unlike an
actual programming console, it is possible to switch directly between the RUN
mode and the PROGRAM mode.)
When the programming console function is started, the PC operation status is
read and reflected at the PC.
The mode lock key element is also a touch switch, and it alternates between the
“lock ON” (with no key displayed) and “lock OFF” (with key displayed) states
when pressed. During the lock ON state, mode selection key operations are in-
effective. The mode displays change as indicated in the figures below during the
lock ON status and during the lock OFF status.
When the programming console function starts, the lock ON status is estab-
lished.
If the RUN, MONITOR, or PROGRAM mode selection key is pressed in the lock
OFF status, the mode changes and the lock ON status is established.
- During lock OFF
