6. Function blocks
6.1 Manufacturer function blocks
6.1.7.5 DL - Data logger
General
easyE4 base devices provide exactly one data logger function
block DL01.
You can use the data logger function block to write operating
data with a timestamp to a log file on a memory card in the
easyE4 base device. In order for this function block to work, a
memory card must always be inserted in the device. You can
select a filename for the log file when configuring the function
block.
Digital function block inputs T1 through T4 and analog function
block inputs I1 through I4 are always logged for each data set.
In addition, the log will indicate which input triggered the log-
ging operation.
Operating principle
Logging can be triggered with a rising edge at one of the trigger inputs T1 through T4 or
a change at analog function block inputs I1 through I4. You can use the Delta ΔI para-
meter for each function block input (I1 through I4) to specify the data change magnitude
starting from which logging will be triggered.
There are two storage modes available for selection:
1. All events will be saved in a single file [ring buffer], meaning that the file will
grow with every save operation. Once the maximum number of data sets is
reached, the entries at the beginning will be overwritten.
2. A new file will be created for each save operation until the number of log files is
reached.
Any byte, word, or double word operand can be connected to analog inputs I1 through
I4.
