CHAPTER 12 DATA COLLECTION AND HISTORIC DISPLAYS
This chapter describes how to set up the data loggers for your application to collect data and how to configure the historic
display objects to display the collected data.
12.1. Data Logger
A data logger can collect and store the values of a data block. You can specify what data block you want to log, determine
the frequency of data sampling, choose the type of memory to save the logged data, and specify how to save the logged
data to files.
You can create up to 16 data loggers for your application. The maximum size of the data block that can be sampled by a
data logger is 128 words.
You can use function button to request the panel to clear logged data or save/load logged data (.ldf/.txt file).
To know how to define a function button, please see Section 5.4.1 Basic Operations of function buttons.
To create a data logger, you may do one of the followings:
1) In the PM Designer's Project Manager tool window, right-click the Data Loggers node of the concerned panel application
and select Add Data Logger.
2) In the PM Designer's menu bar, click Panel to bring up the Panel sub-menu. Click Data Logger in the Panel sub-menu to
bring up the Data Logger pop-up menu. Select Add in the pop-up menu.
12.1.1. Settings
You can set up a data logger with the Data Logger dialog box. There are two ways to open the dialog box of a data logger:
1) In the PM Designer's Project Manager window, right-click the node of the desired data logger and select Properties.
2) In the PM Designer's menu bar, click Panel to bring up the Panel sub-menu. Click Data Logger in the Panel sub-menu to
bring up the Data Logger pop-up menu. Select Properties in the pop-up menu to bring up the data logger list of the current
panel application. Select the data logger in the list.
