Example
Set Points = 1000 and PostTrg = 700, and then there would be 1000 logs, including 300 pieces of data before triggering
and 700 pieces of data after triggering.
10. Datalog is the device to store data logs. If selecting integral to be the format of output values of AD module, we
suggest to use it with 16-bit ADLOG instruction. A space of 500 words would be occupied by using AS04AD-A or
AS06XA-A, while a space ranging from 1 to 2000 words (based on the number of total records) could be occupied by
using AS02ADH-A model. (if using 32-bits DADLOG instruction, the 16-bit data would be expanded to 32 bits which
the data space is taken doubly.) If selecting floating point to be the format of output values of AD module, you must
use it with 32-bit ADLOG instruction. A space of 1000 words would be occupied by using AS04AD-A or AS06XA-A,
while a space ranging from 2 to 4000 words (based on the number of total records) could be occupied by using
AS02ADH-A.
11. CurNo is the number of records which has been sent back to the PLC by the module. When the recording is in progress,
the value of CurNo may not be able to be viewed in a consecutive order as a result of impacts from scan period.
12. Cmplt, the completion flag is used for indicating the logs recording is complete. When Cmplt switches from OFF to
_6 ON, it is indicated that all the log data has been sent to the designated Datalog device. When EN switches from OFF
to ON, the Cmplt flag would be initialized to OFF automatically.
13. If you stop executing this instruction, the designated channel would stop updating the right side values.
14. Refer to the following table for more details when any of the Error flag is ON.
