Hi,

1. You have set a communication intervall for LOGO! (Modbus TCP client). Disable this setting and try again.

2. Your Modbus data table can be optimized. You can read also blocks of register. This may also speed up the communication.

3. Check your IT devices in your network. If routers are used, make sure that the IP adresses of devices with fixed IP-adresses are outside the DHCT range of routers.

4. LOGO! can communicate via Modbus in 80 ms. it point 1 is fixed. Check if your Radwag also offers this speed. 

Hope this helps
