•
With the Toshiba PROSEC T Series, the Error Code is 4 characters long.
On the GLC, Error Numbers are changed to and displayed in Hexadecimal.
•
With the Allen-Bradley PLC-5 and SLC-500 Series, the EXT/STS error codes
have been re-mapped to start at D0 HEX, so they will not conflict with other
error codes. When looking up the error number in the PLC manual, subtract
D0 h from the GLC error code to find its error value.
E.g.
GLC Error Code
PLC Error Code
D1 —> 01
EA —> 1A
This message displays when the lithium backup battery’s voltage for the internal
clock runs. To reset the error, you need to turn the GLC unit’s power OFF and then
ON again. Leave the GLC ON continuously and the battery’s charge will become
sufficient for backup after 24 hours, and will be fully charged in approximately 96
hours. If the battery is incorrectly replaced, the battery may explode. To avoid the
danger, do NOT replace the battery yourself. When the battery needs a replace-
ment, consult with your local GLC distributor.
After changing the backup battery, set up the internal clock.
Chapter 6 – “Initializing the GLC”
The lifetime of the backup battery depends on the ambient tem-
perature and the amount of current being charged and used.
The table below gives a general indication of how long the bat-
tery will last.
When tags are setup beyond the tag limit, all tags in excess of number 384 will be
disabled. Plus, when tags involve registered Windows and loaded screens, they are
disabled in this order: Window Registry, Load Screen.
1. Disabled registered windows start from the last screen used.
2. Disabled loaded screens start from the last screen used.
To correct this problem, reduce the number of tags to within the allowed limit.
The host PLC setup in the Editor program (i.e. the .prw file) does not match the PLC
in use. Use the Error Code that follows the error message to select the proper PLC type
and correct the GLC unit’s INITIALIZE setup data so that it matches this.
