Hi all,
I have a question about OPC topic of Rockwell RSlinx, we use opc client in HMI to read the data in controllogix via Rslinx OPC topic. In the controllogix, we creat an array To_HMI[2000](real), and each tag to hmi(for example Pit_1103_hmi) we alias to To_HMI[index]element. In the HMI, OPC client will read individal tags in PLC such as Pit_1103_HMI, My question: does it increase the read speed for opc client to create To_HMI[2000] array? Thanks,
