text: <s>[INST] Data log options. I would like to log 3 tags, I have an Factorytalk view ME v13 running on a industrial PC, and a control logix 1756-L83E. Which are the best options to do that data log? Considering I need to save it each time it changes, it is around 1.5 sec. [/INST] FactoryTalk View ME has a few options for logging data. The simplest way is to create a datalog model. A datalog can log data upon each change or upon a set interval and will be stored on your industrial PC. You can also you an ActiveX control like MECSVDatalog, which will log the data directly to an excel spreadsheet. Other more expensive options include purchasing software to log the data from the PLC. I don't know what you need to do with the data, and that will probably effect what you decide, but if all you need is to look at the data or display it on the HMI then a datalog model would do well.\n </s>
