1.3.9 Diverting the PLC program that was developed using PLC4B
(Note) PLC4B and LIST4B can not be used with C64. This section describes the method to use
the ladder data on the C64 series system, however, the ladder data here must be created
with PLC4B of the former-model CNC.

(a) Creation
The PLC program created for the old model is output in a list format.
(b) Conversion
Using CLST6L (ladder list converter), the output program is converted into a PLC program (list
format). Using GX Converter (data conversion software package), the list format program is
converted into the GX Developer data.
(c) Editing/transfer
The resultant program can be handled like a newly created PLC program.
