11.2.2.5 Start Mode of an Ether Link

There are three start modes. Please refer to the table below for more information.

During the operation of the PLC, no data exchange is performed.

When the PLC runs, data exchange is performed.

The performance of data exchange depends on a special auxiliary relay in the PLC.

After users select SM Flag, they can set the initial state of the related special auxiliary

*. Please refer to manuals or technical documents for more information about special auxiliary relays related to

Ether Links.

The execution of an Ether Link is based on the nodes in a network. If some of the ports that a node has are

connected to a network, users can set the start modes of the ports separately. When the Ether Link constructed

is executed, the system automatically distributes reading/writing work to the ports according to the start modes

of the ports. If a port is disconnected, the system will pass the work belonging to the port to another port.

There are three ways to set the start mode of a node.

Right-click CPU information or module information, and then click Set Startup Mode on the context menu.
