FX Series Programmable Controlers

5-116

This instruction allows an FX PLC to read the
machine codes of an F

2

-30GM. There are 64

machine code points in the F

2

-30GM. These are

numbered in octal, i.e. 0 to 77 and are prefixed by
M.

a) The head address I/O number for both Sand D

1 

is determined by the position of the FX

2

-

24EI (connected to the F

2

-30GM) within the expansion chain.

b) When the F

2

-30GM operates a machine code (one of the M0 to M77 devices), an

associated destination device (D2) is activated. D2 devices directly map to the machine
codes of the F

2

-30GM, i.e. when the F

2

-30GM activates M7, D

2+7 

(in octal) at the FX PLC

also activates. If the data used in the sample instruction above is used and M77 at the F

2

-

30GM is ON - so will (D

2+77 

an octal addition) M577 at the FX PLC be ON (while the MCDE

instruction is active).

c) To make the associate numbering easy between FX and F

2

-30GM it is recommended that

the lower two digits of the head address used to specify D

2 

are zero, i.e.’

00’ when S or M

devices are used in the FX PLC.

d) For more information please see page 9-5.
