The personal computer link:

(1) Is a communication link that is dedicated for the FA-M3 R and allows the device data within

sequence CPUs to be read or written from other equipment (personal computers, display units,

etc.) without intervention of a sequence program, and also allows a sequence program to notify

events.

(2) Allows you to select the network hardware specification from RS-232-C, RS-422, and Ethernet as

required.

(3) Allows use of display units from various manufacturers that support the FA-M3 R-specific personal

computer link protocol.

Modules that support personal computer link commands:

F3LC11- N personal computer link module

F3LC12-1F personal computer link module

F3SP

sequence CPU module

F3LE01-1N Ethernet interface module

Differences in personal computer link between Ethernet interface module and other modules:

All modules support ASCII-coded commands and responses, but only the Ethernet interface module supports

binary-coded commands and responses. Note that the Ethernet interface module uses different header and

termination codes in ASCII mode from those of other modules.
