The programming tool port can also be used for direct
connection to a personal computer.
Note:
Communication between one computer and 32 FP-M control boards
Using a C-NET adapter, a maximum of 32 FP-M control boards can be connected with one personal computer. If a
bar code reader is connected via the RS232C port, this system can be used for the collection of various production
