Question

The modbus to server is sending empty array

Answer 1

Hello,

With which device you are testing?

Have you configured Modbus TCP/Serial Master so that router would collect data?

What data are  you getting on your server?

Could you please PM me with the troubleshoot file (System -> Administration -> Troubleshoot) of the device when issue persist?

Where are some WiKi links which should help you to configure Modbus on your device:
