Setting up communication between AB & Siemens (Part. 1)
Introduction
The main propose of this is explain how to set up a communication between an AB PLC and a Siemens PLCs using Profibus Protocol.
The equipment required to make the communication are enlisted below.
- CPU Siemens with a DP Port.
- PLC Allen Bradley capable to support a 3dr Party Profibus Module.
- Prosoft Module (Profibus DP Slave Communication Module).
The next image shows the architecture of the network that is suggested.
Set up the module on the Siemens network
To set up the module on the Siemens network we need to follow the steps below.
1.- Open Simatic Manager.
2.- Once opened, we should open the Project on File->Open. Next find and select Hardware like its show below.
3.- Double click on Hardware and it will open the HW Config program. Here is where we need to add a Prosoft Module GSD, the GSD file is named “PSFT0988.gsd”. to add the GSD file in the HW Config program we need go to the main menu and find tools, next we find and select the option Install GSD File as its show in the image below.
4.- Once the GSD file is installed we have to look forward in the explorer tree showed in the right side of the program (Hardware Catalog) to add it into the Hardware Config area as its show below.
5.- Now we need to assign to the module an address node to work in the network and also configure the decentralized periphery adding how many words input/output we are going to need. In the image below are showed an example of the words that we can use.
6.- Once we select the words that we need, we have to drag and drop the words into the decentralized periphery area, as its show below we select 16 words input and 16 words output to share information.
7.- Now we take note of the registers that were assigned to the inputs and outpus words, in the example above the registers assigned were:
Notice that those registers will be different depends on the project IO configuration!!!
8.- Now we have to put the information to share on these registers, input registers are information read it from an AB PLC and the Outpus registers are the information that you will write on the AB PLC.
