7 PLC Advance S7 300 PLC Simatic manger PG/PC & Simulation Setting
In SIMATIC Manager for S7-300, configuring the PG/PC Interface and simulation settings allows you to establish communication between the programming device (PG/PC) and the PLC, or to use a simulation for testing without hardware. Here’s how to configure both:
1. PG/PC Interface Setting
This configuration allows the programming device (PG or PC) to communicate with the PLC or a simulation.
Steps to Set the PG/PC Interface:
Open SIMATIC Manager.
Go to "Options" in the menu bar and select Set PG/PC Interface.
In the "Interface Configuration" dialog box, select the correct interface for communication:
MPI: If using the MPI (Multi-Point Interface) network.
PROFIBUS: If using a PROFIBUS network.
Ethernet: If using TCP/IP (PROFINET or Industrial Ethernet) for communication.
Select the Adapter:
If you are using a PC Adapter (USB), select PC Adapter (MPI) or PC Adapter (PROFIBUS) depending on the network type.
If using an Ethernet connection, select TCP/IP or IE General.
Check Settings: After selecting the interface, click on Properties to check or configure communication parameters like baud rate, addresses, etc.
Test Communication: Go to Accessible Nodes (via the "PLC" menu) to verify that the PC can detect the PLC.
2. Simulation Settings (PLCSIM)
SIMATIC Manager allows for simulation using the PLCSIM software, which mimics a real PLC for testing your program without hardware.
Steps to Set Up Simulation:
Install and Launch PLCSIM: Ensure that PLCSIM (SIMATIC PLC Simulator) is installed and running.
In SIMATIC Manager, go to Options - Set PG/PC Interface.
Select the Interface for PLCSIM:
Choose PLCSIM (MPI) or PLCSIM (PROFIBUS), depending on how you want to simulate the communication network.
For Ethernet, select PLCSIM TCP/IP.
Download to PLCSIM:
In SIMATIC Manager, download the program to PLCSIM just as you would to a real PLC:
Click PLC -- Download.
You should now see the program running in the PLCSIM window.
Simulate I/O:
In PLCSIM, you can manually toggle inputs and monitor outputs to simulate the operation of your PLC program.
Monitor and Debug: You can monitor program execution in real-time using PLCSIM as if it were a real PLC, testing logic and verifying performance.
Key Tips:
Make sure the interface settings (e.g., baud rate, communication protocol) match between the programming device and the PLC or simulation.
For simulation, use PLCSIM to thoroughly test your program before deploying it to the actual hardware.
