Datalogging
This menu is not visible in the User mode.
In this menu, the settings for datalogging are defined via CAN bus or on the SD card of the controller
for analogue and digital values.
Datalogging Settings
Here, you can define whether the logging values are stored on the SD card
for the controller and if so, at what intervals.
The logged daily log files are stored in the LOG/year folder. Logging only
takes place when the SD card is inserted.
If the memory available on the SD card falls below 50 MB, the oldest daily
log files will be automatically deleted. The logged values can be read out
using Winsol software on the SD card (see Winsol manual).
Datalogging Analogue/Digital
The settings apply to both datalogging on the SD card for the controller and for CAN datalogging with
the C.M.I.
Each controller can issue a maximum of 64 digital and 64 analogue values that are defined in this
sub-menu.
The sources for the logged values can be inputs, outputs, function output variables, fixed values, sys
-
tem values, and DL and CAN bus inputs.
Note: Digital inputs
must be defined within the range of
digital
values.
Any number of counter functions (but a maximum of 64 analogue values) can be logged. Like all oth
-
er analogue values, the counter values to be logged are entered into the "Analogue datalogging" list.
CAN datalogging requires at least version 1.25 on the C.M.I. datalogger and a Winsol version of at
least 2.06.
CAN datalogging is only possible with the C.M.I. datalogger. In contrast to data recording via the DL
bus, the data to be logged via the CAN-bus can be freely selected. There is no constant data output.
When requested by a C.M.I., the controller saves the current values to a logging buffer and locks it to
prevent it from being overwritten (when requests are received from another C.M.I.) until the data is
read out and the logging buffer has been enabled again.
The settings required on the C.M.I. for datalogging via CAN bus are described in the C.M.I.'s online
help.
