How many instances of MB_TCP_Server and MB_TCP_Client can I run on AXC F 3152? I have seen that there is a limit of 16 and 32 connections(resp) limit for other vendors like GE RX3i. However, I could not find that particular info in the documentation.
I reached out to PLCnext support about this, but haven’t heard any response yet. Please help answering my question.
Here is the answer from the controls support team:
[quote]for PLCnext there is no limit of MB TCP client or server. The limit is the CPU Load him self of the controller (application)[/quote]
Sorry that you did not get an answer when you reached out to PLCnext support earlier. Can you tell me what support channel you used in that case, so we can check what went wrong?
Martin, PLCNext Store support and sent an email. I have not received any response till date.
In regards to your response on the MB TCP/Server limits, where can I find the controller limitations? I would like to keep that info in mind when developing the application.
I found the message you sent last Thursday (10 March) from the PLCnext Store. It appears that this message was sent using the general „Support“ button on the Store home page, which goes to a general Store support team. Unfortunately that message was not forwarded to the developers of the Modbus TCP library. I have flagged this problem with the Store support team.
To avoid this problem in future, it is better to send a message to the developers directly, using the „Contact“ button on the product page of the specific Store app (in this case, the Modbus TCP Library app).

The features of each controller can be found here:

Unfortunately this does not give any indication of how many function block instances of any specific type can be created in a single PLCnext Engineer project. The only way to find out is to create a project and then try running it.
