1, PC/PG port selection: PLCSIM (MPI) in STEP7, MPI (WINCC)-> PLCSIM(MPI) in WINCC.

2. First, write the control program in STEP7V54 software.

3. Open S7-PLCSIMV54 software, check the following options in the pop-up window, click the second option, and select the project to open the STEP7V54 program.

4. Download the program and run it.

5. Open WINCCV6.2 to create a new project, add a new driver in variable management, select S7, then create a new connection in MPI, change the slot number to 2 in the properties, right-click MPI- > System Parameters-> Unit-> and select PLCSIM(MPI) in the logical equipment item.

6. Create a new variable and edit the screen, then save and run. (same as version 60)

Second, the simulation of TCP/IP network 1,

1, PC/PG port selection: PLCSIM(RFC 1006) is selected in STEP7, and CP _ I2 _1:-> PLCSIM (RFC1006) is selected in WINCC.

2. First, configure the hardware (with CP343- 1 and fill in the IP address) in STEP7V54 software and compile the control program.

3. Open S7-PLCSIMV54 software, check the following options in the pop-up window, click the second option, and select the project to open the STEP7V54 program.

4. Download the program and run it.

5. Open WINCCV6.2 to create a new project, add a new driver in variable management, select S7, then create a new connection in TCP/IP (remember to fill in the IP address when configuring STEP7), and change the slot number to 2. Right-click TCP/IP- > system parameters-> unit-> and select "CP_I2_ 1:" in the logical device item.

6. Create a new variable and edit the screen, then save and run. (same as the 60th edition) III. Simulation of PROFIBUS network 1, PG/PC interface selection: STEP7 selection.

S7 one (step 7)-> PLCSIM (PROFIBUS), and WINCC selects CP _ I2 _1:-> PLCSIM (PROFIBUS). 2、

Create a new connection in PROFIBUS in WINCC, and then enter PROFIBUS system parameters-> unit-> logical device name: PLCSIM(PROFIBUS). other

Same as MPI and TCP/IP simulation.
