SYSMAC NET Link System
The SYSMAC NET Link System is a LAN (local area network) for use in factory
automation systems. The SYSMAC NET Link System can consist of up to 128
nodes among which communications may be accomplished via datagrams,
data transfers, or automatic data links.
Datagrams transmit and receive data using a command/response format. Com
-
mands can be issued from the user program by the DELIVER COMMAND in-
struction (CMND(194)).
Data can also be transmitted and received using the NETWORK SEND and
NETWORK RECEIVE (SEND(192)/RECV(193)) instructions in the user pro-
gram. Up to 256 words of data can be transferred for each instruction.
Automatic data links allow PCs and computers to create common data areas.
