USB-Modbus to Modbus-TCP Gateway Performance


Below are 5 videos on reading speeds with the ACE PLC and the ACE-GTW-MB Modbus gateway.

For testing, we run a timer in ms in the ACE PLC, then read it directly via USB or via TCP through the gateway.

You can download the videos, and run them slowly to check the time (value of the timer read) between 2 Modbus readings.

For know the polling time, you need to see 2 successive values, for example, 4102 and 4132, this means that we can read every 30 ms.
