This example takes S7-200 (CPU224XP) and SMART200 as an example to introduce how to exchange data between them.
The DB9 male port (X1) of BCNet is connected to the PPI port of S7-200, and the Ethernet port of SMART200 comes with BCNet is connected to the BCNet-S7200Plus through a switch. BCNet configures the exchange command through BCDevice tool to realize real-time and efficient data exchange of S7-200 and SMART200.
Configure BCNet module data exchange commands
1, open BCDevice, click [Search Device], search for BCNet-S7200Plus, and then click [Modify Device Parameters].
2, Create a new client
Click Data Exchange, right click to create a new client 0.
The IP address of the remote server is the IP address of the SMART200, set here to 192.168.1.69; the communication port number of the remote server, the default is 102; the connection timeout time is 10S by default.
Local TSAP Remote TSAP
Any 01 00/01
Any 02 00/01
Any 03 00/01
Click Confirm to create the client.
3, Configure data exchange commands in the client
Click New command (VW100~VW108 of SMART200 reads VW100~VW108 of S7-200).
Select [Local→Remote], transmit 5 words; transmit timeout setting layer 2S.
 Local site (S7-200) set the station address of the PLC of the bus where BCNet is located, select DB block for data area, DB number 1 (for S7200, area V corresponds to DB1), byte offset 100, bit offset ignored.
 The PLC address of the remote station (SMART200) does not need to be set, the data area selects DB block, DB number is 1, (for SMART200, V area corresponds to DB1) byte offset is 100, bit offset is ignored.
 Click the [Check] button to check the rules, and click the [Confirm] button to generate the command.
4, Client monitoring
Click the client monitoring button, [Error Message] is no error, and [Correct] has data jumping, which means the communication is successful.
Verify the data exchange
1, Open the status table of STEP7-Micro/WIN and change the data of VW100~VW108 to 1, 2, 3, 4, 5 respectively;
2, open the status table of STEP7-Micro/WIN SMART200 to monitor the data of VW100~VW108.
Both data are exactly the same
