BCNet-S7MPI connects to Siemens S7300 PLC; BCNet-S7PPI connects to Siemens S7200 PLC; in IFIX software, the communication method of S7TCP/IP driven by S7A is used.
Take the S7 TCP driver (S7A) connected to one S7300 and one S7200 as an example
Set the parameters of BCNet-S7 module
Using Siemens S7TCP driver to communicate, you need to pay attention to the parameter “S7TCP target PLC address”, you need to fill in the PLC station address.
Example: BCNet-S7MPI, IP address: 192.168.1.188, S7TCP target PLC address: 2.
BCNet-S7PPI, IP address: 192.168.1.189, S7TCP target PLC address: 2.
Install Siemens S7TCP driver “S7A”; configure S7A driver in “SCU-FIX”.
S7300 configuration.
1)The following configuration, “Primary”, select “S7 TCP/IP”.
2)”Dest IP Address”, fill in the IP address of BCNet-S7MPI module: “192.168.1.188”; “Tcp Port “, fill in: “102”; “PLC Type”, select: “S7300/400”; other parameters default.
3)Create the variables for each zone according to the actual project.
S7200 configuration.
1)the following configuration, “Primary”, select “S7 TCP/IP”.
2)”Dest IP Address”, fill in the IP address of BCNet-S7PPI module: “192.168.1.189”; “Tcp Port “, fill in: “102”; “PLC Type”, select: “S7200”; other parameters default.
3)According to the actual project, establish the variables in each zone (the data in zone V of S7200 corresponds to DB1, and the data in other zones are the same).
