Creating a Profinet link
As explained in the topic "Overview of the universal press system", the press can be controlled by a PLC, using a PROFINET connection.
Below is a brief list of existing PROFINET commands:
•Selection of the operating mode (Manual or Automatic)
•Request for go up or go down in JOG (run on sight)
•Manual movement (position, abs/rel. mode, speed, acc./dec. and start manual positioning)
•Sending the part program number to be activated
•Executing the active part-program
For more information on the different PROFINET commands, see the help topic "Control the press by a PLC".
Wiring a PROFINET connection between the press and a PLC
We will take as an example a Siemens PLC from the S7-1500 range.
To be able to communicate with the press via PROFINET, you must make the connection shown in Figure 1.
The connection to the PC on which the MecaMotion software is located is shown as a broken line and the PROFINET connection to the PLC is shown as a continuous line.
Figure 1: Diagram of the connections with the PLC and PC
Creation of the PROFINET connection in the hardware configuration of the PLC
The example below is made with Siemens TIA PORTAL software.
First, in the programming software, you must create a new project and add the PLC you are going to use (example S7-1500).
Then, install the GSD file provided with the press, to do so, click on the "Options" tab and then "manage general station description files".
Figure 2: Opening the GSD file manager
Choose the source path and install the GSD file.
Figure 3: Installing the GSD press file
Once the GSD file is installed, you will find the press element in the hardware catalogue on the right side of the screen. The path is as follows: Other field devices -> PROFINET IO -> PLCs & Cps -> SIEMENS AG -> D410 -> Presse.
Drag and drop the press element into the network view.
Figure 4: Inserting the press element into the network view
On the press element, click on "not assigned" and choose the PLC with which you want to create the PROFINET link.
Figure 5: Assignment to the PROFINET network
The PROFINET link is now created, all you have to do is enter the IP addresses and subnetwork masks of the devices. You will also need to define the address ranges of the Profinet inputs/outputs of the press.
