To change your GLC unit’s general operation settings, use the GLC unit’s
OFFLINE mode to access the items in the
MAIN MENU
|
INITIALIZE
option.
This chapter explains each of the
OFFLINE
mode’s
INITIALIZE
items. However,
there are two (2) types of
INITIALIZE
settings, those for the
1:1
connection and
those for the
n:1
(multi-link) connection
*1
.
The
n:1
mark appears on original menu items related to n:1 multi-link connection
items. If there is no mark, the menu item is common to both 1:1 and n:1 connec-
tions.
1:1
A single (1) GLC is connected with a single (1) PLC.
n:1
Multiple GLCs are connected with a single PLC. The GLCs successively
pass a
PLC Access Token
(exclusive PLC interaction key) among themselves
to designate which unit can communicate with the PLC.
•
If you transfer the GLC unit’s system file data to the GLC
via your screen design software
*2
, the GLC operates using
that data. If the GLC System file has been correctly set up
and transferred, then setting up the INITIALIZE items is
unnecessary.
For more information about GLC System files, re-
fer to the
Operation Manual, Section 1.1.2 –
“Screen Types”
(included with screen creation soft-
ware).
•
In instances where “GP” is displayed on the GLC unit’s
Offline screen, the term “GLC” can be substituted.
