Backplane slot number
The backplane for the FP2 is specified by the total number of slots, i.e., 14-module type,
including the connectors for the power supply unit and CPU. The number of connectors
(or slots) remaining for the I/O units and intelligent units is then the module number of
the backplane minus the number of modules for the power supply unit and CPU.
Similarly, the number of connectors (or slots) remaining for the I/O units on expansion
backplanes is the module number of the backplane minus the number of modules for
the power supply unit.
Expansion backplanes
1. FP2 backplane
− Does not support expansion with 5-module type backplanes.
− Backplanes that are not the 5-module type can be used as expansion backplanes.
2. FP2 backplane H type
− This backplane is functionally equivalent to the backplane for FP3.
− There are the basic backplane H type for installing I/O units and the expansion
backplane H type for adding I/O units more.
− The basic backplane cannot be used as an expansion backplane.
Removal and Installation of Expansion Memory Unit
During removal and installation of expansion memory unit, the contents of the internal
RAM may be erased, so be sure to save a copy of the program and data onto a disk
before beginning the operations.
Use programming tool software (NPST−GR/FPWIN GR) for backup purposes.
Before rewriting the backed up program and data to the programmable controller, be
sure to clear the program in the programmable controller.
