Using Memory Cassettes
Section 3-11
2.
Use the Programming Device to turn ON AR 1401. The information will be
read from the Memory Cassette to the CQM1H and AR 1401 will be turned
OFF automatically when the read operation is completed.
Automatic Transfer at
Startup
If pin 2 of the CPU Unit’s DIP switch is ON, data will automatically be read
from the Memory Cassette when the power supply is turned ON to the
CQM1H. A memory error will occur and operation won’t be possible if an error
occurs during transfer of data between the Memory Cassette and CQM1H
memory.
!Caution
Be absolutely sure that the power is turned OFF before changing CQM1H DIP
switch settings.
3-11-5 Comparing Memory Cassette Contents
The contents of the Memory Cassette can be compared to the contents of the
CQM1H’s memory to check to see if they are the same. This comparison can
be performed for any type of Memory Cassette.
Procedure
Use the following procedure.
1,2,3...
1.
Check to see that the CQM1H is in PROGRAM mode. If it is in either RUN
or MONITOR mode, use the Programming Device to change to PRO-
GRAM mode.
2.
Turn ON AR 1402 from the Programming Device. The contents of the
Memory Cassette will be compared to the contents of CQM1H memory
and AR 1402 will be turned OFF automatically when the comparison is
completed.
3.
Check the status of AR 1403 to see the results of the comparison. AR 1403
will be ON if the contents were not the same or if the comparison was not
possible because the CQM1H was not in PROGRAM mode. If AR 1403 is
OFF, the comparison was successful and the contents were the same.
AR 1403 cannot be controlled from the program or from a Programming
Device. It is controlled by the results of comparison only.
If a comparison is attempted with the CQM1H in any mode but PROGRAM
mode, a non-fatal error will occur (FAL 9D) and AR 1412 will turn ON.
Although AR 1403 will also turn ON, no comparison will have been performed.
AR 1403 will also turn ON if a comparison is attempted without a Memory
Cassette mounted in the CQM1H.
