I use Profibus DP Master simulator to establish communication with two units in the Profibus network. Under search slave window I could see both of them. But I could not open the Communicator window, which would work with both nodes. Profibus Master Simulator version is 22.214.171.124. I can establish communication with each of them, but not with both of them at the same time. Please let me know what should be done. Thanks.
While the Master can connect to a bus with multiple devices i believe the software is limited to only read/write to one device at a time. I am verifying this with a colleague and will let you know if there is a way to open multiple connections at once.
Thanks for the answer. Do you have any updates for me?
Yes, It looks like the simulator only allows for one communication window at a time.
Thanks for the answer. What would you suggest to use if we need to test at lest 2 or 3 units in the loop. What would be the best solution to check it in the office without purchasing expensive hardware?
Best regards, Stas.
Hi @Stas ,
I am not sure of an option using the software, of course you can switch the node as needed in the software but I assume you are looking to read the data at the same time.
I am not sure what you are looking at and consider expensive for a hardware solution but a possible solution might be an anybus X-gateway AB7629 Profibus master to ModbusTCP/ethernet/IP gateway. This could be configured to read the profibus devices then allow you to read the data via modbus TCP.
