Using The FX2-24EI With F
Series Special Function Blocks
Series Special Function Blocks
The FX
2
-24EI allows an FX base unit to be directly connected to an one of the following F
series special function blocks:
a) The F-16NT/NP, a Melsec Net Mini interface
b) The F2-6A, a combine analog 4 input and 2 output unit
c) The F2-32RM, a programmable CAM sequencer
d) The F2-30GM, a pulse train positioning unit
One 24EI unit can control one F series special function unit.

The ‘24EI’ units are added to an FX system in the same manner as an additional discreet
I/O module. Each 24EI occupies 16 input points and 8 output points, the diagram below
illustrates this point. Experienced users may notice that the example shown in the
diagram below would require too much power from the CPU unit (FX-48MR in this case)
based on the I/O count.

This is not the case. The FX2-24EI is really a communications module. It does not
directly drive any discreet I/O. For the sake of power calculations it can be assumed that
it only occupies 8 standard I/O points. This means that the configuration shown in the
diagram actually occupies 32 points (three FX2-24EI’s and one FX-8EX) of I/O for the
sake of power consumption calculations BUT actually occupies 80 points of addressable
I/O.

Connection Of Earth Points When Using F Series Special Function Blocks
•
When using the F series special function blocks the special function blocks earth
terminal should be connected to the [SG] terminal of the FX CPU unit. However, when
using the F-16NP/NT unit the [SG] terminal of the F-16NP/NT should on NO account be
connected to the [SG] terminal of the FX. The function of these terminals are completely
different and are hence NOT compatible.
