SYSMAC LINK System

Networks can also be created using SYSMAC LINK Systems. A SYSMAC LINK

System can consist of up to 62 PCs, including the CV500, CV1000, CV2000,

CVM1, C200H, C1000H, and C2000H. Communications between the PCs is ac-

complished via datagrams, data transfers, or automatic data links in ways simi-

lar to the SYSMAC NET Link System.

The main differences between SYSMAC NET Link and SYSMAC LINK Systems

is in the structure of automatic data links and in the system configuration, e.g.,

only PCs can be linked in SYSMAC LINK Systems, whereas other devices can

form nodes in SYSMAC NET Link Systems.

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.
