Special Operations
The special operations feature provides a mechanism to config-
ure the MFP module to do a one-time special operation rather
than entering its normal mode of operation. Steps one through
eight explain how to set the MFP module for special operations
and reset it for normal operation. Table
shows the
dipswitch settings and explains each special operation.

Normal operation.

The compact configuration function moves configured function
blocks to the top of the NVRAM memory while moving free space
to the bottom. This condenses the configured function blocks while
providing the largest possible area of contiguous unconfigured
function blocks to the user. To enable this function, open the pole
and insert the module into the module mounting unit. After a short
time period (directly proportional to the configuration size) the
module will return to the mode it was in prior to being reset for the
compact operation.

Normal operation.

Initializes NVRAM (erase configuration) memory. To enable this
function, open the pole and insert the module into the module
mounting unit. When front panel LEDs 1, 2, and 4 are ON, remove
the module, put the pole in the closed position, and insert the mod-
ule. The module is now ready to be configured.
NOTE: This position must remain CLOSED for normal operation.

Primary MFP module.

Redundant MFP module.
NOTES: 0 = CLOSED or ON, 1 = OPEN or OFF; shaded areas designate mandatory pole settings.
1. Disabling the checksum routine is sometimes done by development personnel and should never be done for normal operation. The check-
sum routine provides additional module integrity and should be active whenever the module is controlling a process.
2. Leaving this option enabled causes the configuration to be compacted every time the module is reset thereby increasing the startup time.
This increase becomes more substantial as the size of the configuration increases. Therefore, do not leave this option enabled longer than
necessary. Disabling this option stops any further compacting operations. It does not uncompact any previously compacted configuration.
