●
Baud Rate
(required)
Eight options are available for different scenarios: 20 Kbps, 50 Kbps, 100 Kbps, 125 Kbps, 250 Kbps,
500 Kbps, 800 Kbps, and 1 Mbps. You can select the desired option in the drop-down box, and then
download the conguration to the master station (this parameter is valid for the master station only, and
needs to be manually modied on a slave station). You can select the baud rate based on the bus load and
communication distance.
●
Net Heartbeat
(optional)
All slave stations send heartbeats to the master station at a specied interval. The master station monitors
the state (online or ofine) of each slave station through the heartbeat mechanism. Slave stations monitor
the state of the master station through its heartbeats. (It is recommended that the interval be more than 200
ms.) If you deselect this parameter, the heartbeat function is disabled and the system cannot monitor the
network.
●
Master Station No.
(required)
In this example, the master station number is the number of the PLC that serves as a master station. The
number cannot be changed. If the number entered is inconsistent with the actual number, the PLC will
determine that the downloaded conguration is invalid. For example, if you enter 7, the conguration is valid
only when downloaded to station 7. Station 7 then assigns the conguration to other stations. The CANlink
network conguration is downloaded to the master station and then assigned to slave stations. In this way,
the system can monitor and manage the entire network through the master station in the background.
●
Master Station
Synchronous Write Trigger Element
(optional)
It is an element triggering Synchronous Write for the master station. When a trigger element (M) is set, the
corresponding conguration takes effect. The element is automatically reset after data is sent.
