1.2.1 Installing the Tools

In the C64 Series PLC development environment, it is assumed that the various tools are used on
an IBM PC/AT compatible machine. Prepare each tool so that it is IBM PC/AT compatible machine.
Refer to the enclosed Operating Manual for the setup and start procedures of each tool.

1.2.2 Connecting the Serial Cable

As for the serial port connected with the CNC, refer to the MELDAS C6/C64/C64T Connection and
Maintenance Manual (BNP-B2255).
