Introduction to OPC Unified Architecture (UA) Live Demo Summary Questions & Answers Here is the agenda of todays webinar. Win Worrall Applications Engineer Direct Line: +1 (704)Ģ Agenda Introduction to the OPC Data Logger What are Write Backs My name is slim-shady and I am excited to show you how you can quickly, easily and reliably log your OPC data to a variety of destinations using the highly affordable, yet very powerful OPC DataLogger. I have tried another OPC data logger from a different vendor with no luck.How to Avoid DCOM Using OPC UA Hello everyone, thank you for joining us on this webinar. I've been looking at this for a few days and I'm stuck. This works for the older PLC but since the data from the newer PLC is not available in the non-optimised connection, I cannot send it to the data logger.Ĭan I force the newer CPU to communicate with SIMATIC NET OPC via the same (non-optimised?) protocol/method as the older CPU? I will shortly be adding a third PLC which is of the newer type, so I need to get this sorted ASAP. I can easily create a non-optimised transfer DB in each plc and send this to the OPC server. This means I can only log data from non-optimised blocks. In OPC data logger, I can only browse and log data from the older PLC. The folders appear in OPCSimaticNET.S7 but the tags are not shown. This shows me all tags/blocks including non-optimised blocks for this PLC. Even though the CPU contains some optimised blocks, these do not even show in the OPCSimaticNET.S7OPT tree.įor the newer PLC, I can only read/write via OPCSimaticNET.S7OPT (optimised). Using OPC scout on the OPC Server, I can successfully browse tags and read/write to both PLCs.ĭata from the older PLC is only accessible via OPCSimaticNET.S7. I am unable to change the parameters of the newer connection. The newer PLC creates only 1 connection (see attached screenshot). When creating an S7 connection to the OPC server in Step7, the older PLC creates two connections (send and receive?). The PLCs have different firmware revisions. On the OPC server, I have enabled all OPC protocols/services.
