Primary MFP module.

Redundant MFP module.
NOTES: 0 = CLOSED or ON, 1 = OPEN or OFF.
1. Disabling the checksum routine is sometimes done by development personnel and should never
be done for normal operation. The checksum 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 start-up 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 previous-
ly compacted configuration.

Jumper
Position
Function
1 - 2
Allows the module to function in early Network 90 systems that
supply -30 VDC. Communication is restricted to module bus in
this position.
2 - 3
Allows communication over the Controlway or module bus.
