2. Protect Keyswitch
3. EM Unit Compartment
4. This compartment contains the Memory Card slot, CPU DIP Switch,
The Protect Keyswitch can be set to write-protect the user program, PC Set-
up, and CPU Bus Unit settings.
The UM PROTECT operation can also be executed from a Programming
Device such as SYSMAC Support Software (SSS) to prevent access (read/
write access) to the program. When both protect functions are applied, the
Protect Keyswitch setting overrides the UM PROTECT operation.
In duplex mode, the Protect Keyswitch’s write-protection is temporarily sus-
pended during duplex synchronization or program transfer. Write-protection
is enabled again after the duplex synchronization or program transfer is
completed.
An EM Unit (sold separately) can be installed in this compartment. See Ex-
pansion Data Memory on page 33 or more details.

Files are not transferred from the Memory Card auto-
matically at start-up.
The program file, PC Setup file, and CPU Bus Unit
settings file will be transferred from the Memory Card
to the CPU Unit automatically at start-up.
(In a duplex system, the files are transferred in the
active CPU Unit only. The files aren’t transferred in
the standby CPU Unit.
The automatic transfer at start-up setting can be
made in the PC Setup as well, but the setting on pin 5
supercedes the PC Setup setting.
The files will not be transferred if the Protect Key-
switch is set to PROTECT.)
Not used. (Leave this pin set to OFF.)
