The following procedures can be used to read UM Area data from, write UM Area
data to, and compare UM Area data on an EEPROM Memory Cassette mounted
to a C200HS CPU. This UM Area data can include the user program, fixed DM
data such as the PC Setup, expansion DM data, I/O comment data, I/O table
data, and UM Area allocation data. The procedures cannot be used to write to
EPROM Memory Cassettes, which require a PROM writer. Refer to the LSS op-
eration manuals for PROM writer procedures.
Note The data inside the Memory Cassette should be protected by turning on the
write-protect switch whenever you are not planning to write to the Cassette.
The following procedure is used to write UM Area data from the C200HS CPU to
a Memory Cassette mounted in the CPU.
1. Turn off the write-protect switch on the Memory Cassette to write-enable it.
2. Make sure that power to the C200HS CPU is turned OFF.
3. Mount the Memory Cassette to the CPU.
Function
Data transferred to Memory Cassette when Bit is turned
ON in PROGRAM mode. Bit will automatically turn OFF. ON in PROGRAM mode. Bit will automatically turn OFF.
An error will be produced if turned ON in any other
mode.
Data will not be transferred from UM to the Memory
Cassette if an error occurs (except for Board Checksum
Error). Detailed information on checksum errors E ) D t il d i f ti
occurring in the Memory Cassette will not be output to occurring in the Memory Cassette will not be output to
SR 272 because the information is not needed. Repeat
the transmission if SR 27015 is ON. the transmission if SR 27015 is ON.

ON in PROGRAM mode. Bit will automatically turn OFF. ON in PROGRAM mode. Bit will automatically turn OFF.
An error will be produced if turned ON in any other
