My primary objective is to retrieve the field data collected by the Installed Moxa ioLogik2500 RTU in the field. I do not require any logic implementation or mathematical functions (except scaling) on this collected data. My sole requirement is to obtain the raw field data, convert it to engineering units, and transmit it to the Master PLC via Modbus TCP.
So based on my understanding from user manuals provided by MOXA, the data from all types of inputs and outputs are already mapped onto predefined Modbus registers, which are displayed in the IOxpress Modbus TCP Slave window as shown in picture attached. The starting address of these registers is editable, and the reference address indicates the range of addresses. Between the start address and the reference address, I can place my data. Therefore, to fetch data from the Moxa ioLogik2500, users need to directly access these aforementioned registers from the Master PLC via Modbus TCP/IP. Consequently, they will receive the data recorded by input/output channels without any need of Click & Go programming. However, the Network configuration and settings will be done as prerequisites.
I seek clarity on whether our approach is correct. If not, I would appreciate guidance on the correct method to achieve our target
