Features
You can construct the command system (T-Link) and monitoring system (SX bus) with separate link
systems. While giving command via the T-Link, you can perform high-speed data monitoring via the SX
bus.
Detailed specifications
(1) The transmission format of the SX bus is fixed to the monitoring format and dedicated to
monitoring.
You need to configure the monitoring format with transmission format selection (U11) and system
configuration definition.
(2) The link function (link command switch, link edit switch, etc.) is enabled for the T-Link.
(3) The communication error monitoring target is the T-Link, and communication errors occurring on
the SX bus will not be detected.
(4) For the detailed specifications of the T-Link, refer to "6.3 T-Link Interface".
