Hi,
I am using the ModbusTCP interface for the first time on a FBL2360E controller and experiencing a really slow response rate.
Please find attached a log with highlited rows of one query to the controller where you can see:
1. No.3: query to controller
2. No.6: ACK from controller ~56ms later
3. No.11: answer from controller ~111ms later
This happens with every query and gives us a transmission rate of around 7Hz for all queries. This is simply insufficient for our application. Is there something I can do to minimize the response time of the controller or do I need to change interface?
regards, Sergio
