Wecon hmi Muti-link function and settings

Ⅰ.Connection Mode

An example of communication between a PLC and four human-machines is shown in the figure below. Note that human-machines usually communicate with each other via RS485 and every slave must have its own station number. When the system has just one slave, human-machines can also communicate with each other via RS232.

Ⅱ. Parameter settings of Multi-link Communication

Here are the operation procedures of setting communication parameters of Multi-link.

1.Select 【System Parameter】/【Connections and communication】, then select “add” in the screen. Select communication interface of Multi-link in the option of “communication interface” and “Multi-Link Protocol”in the option of “device type”.

2. Set the parameters of the master and the slave，the corresponding number and station number of the slave.

Notes:

The more slaves, the slower the communication speed may be.

The station numbers of the slave must be consecutive numbers starting from one without repeating.

The parameters of the master and the slave must be the same.

The order of the protocol must be the same when choosing the protocol of the master and the slave.

3.After setting the parameters above, select【Tool】/【Project Build】.Then you can download it to the human-machine.
