Omron C200HE ユーザーズマニュアル

The C200HX/HG/HE comes equipped with a built-in RAM for the user’s pro-
gram, so a normal program be created even without installing a Memory Cas-
sette. An optional Memory Cassette can be used to store the program, PC Set-
up, I/O comments, DM area and other data area contents. Refer to the C200HX/
HG/HE Installation Guide for details on installing Memory Cassettes.

The Memory Cassette can be used to store and retrieve UM and IOM data; UM
stored in the Memory Cassette can also be compared to the UM in the PC.

1. The contents of UM (user memory) can be stored in the Memory Cassette

for later retrieval or verification. If pin 2 of the CPU Unit DIP switch is set to
ON, the contents of the Memory Cassette are automatically retrieved when
the PC is turned ON.

The UM area contains the ladder program, fixed DM (such as the PC Setup),
expansion DM, I/O comments, the I/O table, and the UM area allocation in-
formation.

2. The contents of the PC’s I/O memory (IOM) can be stored in the Memory

Cassette for later retrieval.

IOM includes the IR area, SR area, LR area, HR area, AR area, timer and
counter PVs, DM 0000 through DM 6143, and EM 0000 through EM 6143.

UM and IOM data is completely compatible between the C200HX/HG/HE and
the C200HS data, except the portion of the C200HX/HG/HE data areas that ex-
ceed the capacity of the C200HS and the new instructions (BXF2(––),
IEMS(––), IORD(––), IOWR(––), PMCR(––), STUP(––), and XFR2(––)) that
aren’t supported by the C200HS CPU Unit. Data area addresses and instruc-
tions that aren’t supported by the C200HS can’t be used in the C200HS. IOM
data can’t be retrieved to the PC’s RAM unless the size of the IOM in the Memory
Cassette matches the size of the IOM in the PC.

There are two types of Memory Cassette available: EEPROM and EPROM. The
following table shows the Memory Cassettes which can be used with the
C200HX/HG/HE PCs.

EEPROM

C200HW-ME04K

The EEPROM Memory Cassette

C200HW-ME08K

can be used to write and read UM
and I/O data to the CPU Unit. It does

and I/O data to the CPU Unit. It does
not require any backup power sup-

ply and will retain its data even after
it is removed from the CPU Unit.

EPROM

16K or 32K
words

C200HS-MP16K

The EPROM chip is not included
with the Memory Cassette; it must
be purchased separately.

1. Data stored in EEPROM won’t be reliable after the contents have been over-

written 50,000 times.

2. Use a standard PROM writer to write a program to the EPROM Memory

Cassette. Connect an EPROM to the EPROM Memory Cassette before
installing the EPROM Memory Cassette to the CPU Unit. The EPROM
Memory Cassette will lose its data if it is removed from the CPU Unit.
