FXCPU Structured Programming Manual

[Basic & Applied Instruction]

This instruction sends the M code numbers M0 to M77 to the PLC from the F

2

-30GM type pulse output unit.

• From  F

2

-30GM type pulse output unit, M code number M0 to M77 is 

sent out to the PLC.

• The content of the device specified by 

, 

 is determined by the 

connection position of FX

2

-24EI type special block.

• When M code output instruction is executed at the F

2

-30GM side, input 

X is operated according to the value 0 to 77 (octal), and the result is 
stored in M500 to M577 in octal notation.
For example, in the case of M code 23, M523 is turned ON.

• For the ease of understanding of correspondence of M code number between the PLC side and the F

2

-

30GM side, it is recommended to set 00 in the lower two digits of device M, S specified by 

.

• In the FX-1GM type pulse output unit, FROM instruction is used instead of MCDE instruction.

The instruction is not provided in the FX

U

 and FX

2C

 PLCs Ver. 3.30 or later.  

This instruction is disused from V3.30 and later.
