7 RUN Mode and Errors
System Version
Protocol Version
The GLC unit enters the RUN mode in two instances: either immediately after
plugging in the unit’s power cord, or from the GLC unit’s
OFFLINE
mode.
The method of GLC startup depends on which “
START TIME
” setting is specified
in the Initialization Settings | System Setup screen.
When START TIME is set to “0”
When the GLC unit’s power cord is connected, the version information screen
appears (see below). The screen designated by the initialization screen file number
(within the Initialization Settings | System Setup screen) appears, and then the
GLC starts to communicate with the PLC.
When START TIME is set to any value other than “0”
When the GLC unit’s power cord is connected, a value appears in the version
information screen (below), which counts down the seconds designated by the
START TIME
setting. The screen designated by the initialization screen file num-
ber (within the Initialization Settings | System Setup screen) appears, and then the
GLC starts to communicate with the PLC.
If the initialization screen’s file number is not designated, or if a number that does
not exist is designated, the version information screen remains displayed.
Depending on the display device’s startup time, it is possible
that the screens shown above may not initially be displayed.
