Omron C200HE ユーザーズマニュアル

The hardware and software settings related to Memory Cassette operations are
described below.

Switch 1 on the Memory Cassette is turned OFF when the Memory Cassette is
shipped. Check the setting on switch 1 before installation.

EEPROM

ON

The data in the Memory Cassette is write-protected.

OFF

The data in the Memory Cassette can be overwritten.

EPROM

ON

27512-equivalent ROM-KD-B EPROM
(32K words, 150 ns access time)

OFF

27256-equivalent ROM-JD-B EPROM
(16K words, 150 ns access time)

SR 269 through SR 273 contain flags and control bits related to Memory Cas-
sette contents and operation. Refer to 3-4 SR (Special Relay) Area for details.

Use the following procedures to transfer UM data to or from a Memory Cassette.
(A PROM writer is required to write data to an EPROM Memory Cassette. Refer
to the SYSMAC Support Software Operation Manual for details.)

Note UM 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 information.

Use the following procedure to write UM data to an EEPROM Memory Cassette.

1. Before turning ON the C200HX/HG/HE’s power supply, make sure that

switch 1 on the Memory Cassette is set to OFF.

2. Turn ON the C200HX/HG/HE and write the ladder program or read an exist-

ing program from a data disk.

3. Switch the C200HX/HG/HE to PROGRAM mode.

4. Use a host computer running SSS or a Programming Console to turn ON

SR 27000 (the Save UM to Cassette Bit). The data will be written from the
PC to the Memory Cassette. SR 27000 will be turned OFF automatically af-
ter the data transfer has been completed.

5. If you want to write-protect the data on the Memory Cassette, turn OFF the

PC and set switch 1 of the Memory Cassette to ON. If this switch is ON, data
in the Memory Cassette will be retained even if SR 27000 is turned ON.

There are two ways to read UM data from a Memory Cassette: automatic trans-
fer at startup or a one-time transfer using a Peripheral Device.
(There is no function that automatically writes data to the Memory Cassette.)

1. Turn ON pin 2 of the CPU Unit’s DIP switch.

2. Install the Memory Cassette containing the data into the C200HX/HG/HE.

3. Turn ON the C200HX/HG/HE’s power supply. The contents of the Memory

Cassette will be transferred to the CPU Unit automatically. A memory error
will occur if the data couldn’t be transferred.

1. Install the Memory Cassette containing the data into the C200HX/HG/HE.

2. Turn ON the C200HX/HG/HE and switch it to PROGRAM mode.

3. Use a host computer running SSS or a Programming Console to turn ON

SR 27001 (the Load UM from Cassette Bit). The data will be read from the
Memory Cassette to the PC. SR 27001 will be turned OFF automatically af-
ter the data transfer has been completed.
