Function and operation explanation
•From F2-30GM 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.
Cautions
