I am setting up a new Siemens S7-1500 PLC that is supposed to talk to an existing Factorytalk ME as the SCADA end.
I am exploring my options but one of the main goals I am requested to accomplish is to have "data buffer" or what is called "data historian" in the middle that will log the data from the PLC and push it to Factorytalk in case a network outage took place.
Siemens PLCs usually have OPC-UA server built within, but the issue I am having is how can I buffer the data and then present it to Factorytalk at a later time? Does OSIsoft have an available solution this particular scenario? Note: I am very new OSIsoft and PI server products.
