Omron CPM1 Programming Manual

Using Memory Cassettes (CQM1 Only) Section 3-5
Follow the procedure outlined below for writing.
1,2,3... 1. Check to see that the write-protect switch on the Memory Cassette is OFF
(i.e., writing enabled). If the switch is ON (i.e., writing not enabled), then
turn the CQM1 power supply off and remove the Memory Cassette before
changing the switch.
2. Check to see that the CQM1 is in PROGRAM mode. If it is in either RUN
or MONITOR mode, use the LSS/SSS to change the mode.
3. Turn ON AR 1400 from the LSS/SSS. The information will be written from
the CQM1 to the Memory Cassette.
4. With the LSS/SSS, clear the forced-set status to turn OFF AR 1400, which
will not change even after the operation is complete. (If the Programming
Console is being used, AR 1400 will automatically turn OFF.)
!Caution Data cannot be written to the Memory Cassette if a memory error has
occurred.
Note If an error occurs while data is being transmitted, a non-fatal error (FAL 9D)
will be generated and the appropriate AR bit (from AR 1412 to AR 1415) will
turn ON/OFF. If this occurs, refer to SECTION 8 Troubleshooting and make
the necessary corrections.
3-5-4 Reading from the Memory Cassette
There are two methods for reading data from the Memory Cassette to the
CQM1: By using a Peripheral Device (e.g., LSS/SSS) or by automatic reading
the contents when the CQM1 is started up.
If the program on the Memory Cassette has expansion instructions with func-
tion codes different from the default settings, make sure that pin 4 of the CPU
Unit’s DIP switch is ON (indicating user-allocated function codes).
Note When data is being read from the Memory Cassette to the CQM1, pin 1 of the
DIP switch on the CQM1 must be OFF (i.e., writing to the DM must be
enabled). Turn off the power to the CQM1 before turning this pin OFF.
Reading from the Memory Cassette can be executed regardless of the type of
Memory Cassette.
If an error occurs while data is being transmitted, a non-fatal error (FAL 9D)
will be generated and the appropriate AR bit (from AR 1412 to AR 1415 will
turn ON/OFF. (If this occurs, refer to the Troubleshooting section and make
the necessary correction.)
Peripheral Device
Operation
To use a peripheral device to read from the Memory Cassette, follow the pro-
cedure outlined below.
1,2,3... 1. Check to see that the CQM1 is in PROGRAM mode. If it is in either RUN
or MONITOR mode, use the peripheral device to change the mode.
2. Use the peripheral device to turn ON AR 1401. The information will be read
from the Memory Cassette to the CQM1.
3. With the LSS/SSS, clear the forced-set status to turn OFF AR 1401, which
will not change even after the operation is complete. (If the Programming
Console is being used, AR 1401 will automatically turn OFF.)
Automatic Reading If pin 2 of the DIP switch on the CQM1 is turned ON (auto-boot), then data will
automatically be read from the Memory Cassette when the power supply is
turned on to the CQM1. Operation will not be possible if an error occurs dur-
ing transfer of data between the Memory Cassette and CQM1 memory.
