SYSMAC LINK System Features

SYSMAC LINK Units are equipped with a variety of special features.
The specialized communications LSIs used in all SYSMAC LINK Units deliver
high speed, reliability, and flexibility in an advanced data link system, while opti-
cal fiber cable systems provide high-speed communications with unparalleled
immunity to noise.
In the event of an error or failure in the polling unit, another node automati-
cally takes over management of the SYSMAC LINK System without stopping
the entire network. SSS or CVSS running on an IBM-PC/AT or compatible
can monitor and/or program PCs anywhere in the network via the SYSMAC
LINK System.
The data link function transfers data to and from other nodes automatically,
establishing simple but powerful peer-to-peer links between nodes. Data links
can be generated automatically between 2, 4, 8, or 16 nodes by changing the
value of just one byte in the AR Area of the start-up node. Or the user can use the
flexibility of manually generating data links to eliminate unused link words,
improve data link I/O response time, and to even create several data link groups
in one network.
The data link communications cycle time can be fixed at a constant value, so
even simultaneous remote programming/monitoring and NETWORK READ/
WRITE instruction (RECV(98)/SEND(90)) execution have no effect on the
data link I/O response time.
PCs can communicate actively with other PCs in the network. The four functions
listed below can be performed from the PC’s program using the SEND(90) and
RECV(98) instructions (SEND(192), RECV(193), and CMND(194) in the CV-
series).
SYSMAC LINK Units are equipped with three RAS functions (RAS is an acro-
nym for reliability, availability, and serviceability). The Polling Unit Backup and
Failed Node Bypass (optical systems only) functions prevent the network from
failing when one Unit fails. The Internode Echo Test function aids in communica-
tions troubleshooting.
Remote monitoring of the network’s operating status also aids in trouble-
shooting and quick correction of communications problems.
Up to 2,966 words can be linked using the data link function with the C200HW-
SLK14/SLK24.
The input interrupt response time is 1 ms maximum when the new SYSMAC
LINK Units are mounted to a C200HX, C200HG, or C200HE PC.
