Hello,
Thank you very much for your reply.
If I use the Data to server function to transmit data, I need to configure the MODBUS. In either the modbus master or modbus serial master, I need to add a slave. In modbus slave, I need to add an instance from which the data will be transmitted by trb 245. In the request configuration, there is an option to select the first register.
From my understanding, the data is read from the first register and the following register.
Therefore, I would like to ask if I want to transmit the data which is sampled by an external device and transmitted to trb 245 via rs-485, which register number should I write to the request configuration part.
I would be appreciated, if you can give some advice or answer to this question.
Kind regards
Z WH
