WECON PI Series HMI can communicate with SIEMENS PLC via Ethernet port. So far, S7-300 and S7-1200 are supported.
2. Address list
There are some difference between HMI address list and PLC real address, this sector introduce the difference between HMI and PLC address.
|Type||Register in HMI||Register in PLC||Format||Range||Note|
|MW0 = MB0-1 MW2 = MB2-3
Using the even address
|MD0 = MB0-3 MD4 = MB4-7|
3. Communication parameters
This sector introduces the setting for communication parameters.
Select the communication protocol when create a new project as Figure 1 shows. Or change the communication protocol for an existing project by click [Project] menu, and select [Communication] in [Settings] toolbar, and click [Setting] to open the protocol list, as Figure 2 shows.
3.2 Communication parameters
Different from the communication by Serial port, it requires set device IP for communication. So please click the [Setting] button in [Device IP] option, and it will pop-up [TCP/IP parameters] as Figure 3 shows.
- PLC IP Address: It is used for entering the PLC IP address;
- PLC Port No.: It is used for entering PLC port Number;
- Network: It is used for selecting type;
Note:The default setting in PLC of PLC port No. is 102, and the default Network type is [TCP_Client_2N]. But please make sure the setting is same as PLC’s in real situation.
