Panasonic FP-X Series manual Reassuring data security, Before, With FP-X

FP-X series

Reassuring data security

Protects your important programs by preventing illegal copies.

Program upload is easily prohibited by tool software FPWIN.

Reading a program from the PLC main unit is virtually impossible.

In the upload-prohibited condition, program transfers to the master memory are also prohibited.

Release of an upload-prohibited condition is possible with a forced release accompanied by a program deletion.

Program updates are easily carried out by transferring the program in the master memory to FP-X even during an upload-prohibi­ ted condition. The transferred program in FP-X is set up with the same upload prohibition and permission conditions used in the master memory.

Using a standard USB port makes it unnecessary to use an an expensive USB conversion adapter/ cable for connecting a PC to the PLC.*

The conventional

RS232C port can also be used.

C30 and C60 control units have a USB port as standard equipment. They can be easi­ ly connected to a PC with a commercially available USB cable (AB type), making pro- gram editing/monitoring available. It is no longer nec- essary to bring a dedicated cable to remote locations.
