Digital Data Output
The data output via RS232 enables to send all measured values and status messages cycli-
cally every 10 s via the serial Interface to a periphery, such as for example to a PC. This
data transfer has to be activated in the menu System Parameters (see 4.8).
Data Output via RS232-Interface, Profibus DP and ModBus has not been part of the EC-
Type Test for measuring technical function. Use of this data is for information and storing
purposes, but not for safety functions.
It is possible to record the data by means of an ExTox Data Logger ET-SL which is available
as accessory (see Chapter 10).
Corresponding Interface Modules (Art.-No. 825009 or 825017) are available for integration
in a Profibus DP- or a ModBus-environment. The specification of the interface is described in
Chapter 6.4. Additional bus systems on request.
6.1
Data Formate
All measured values and texts are sent in ASCII-Format, each separated by a semicolon.
Every single data set is completed by a CR ($0D). This formatting enables to import record-
ed data sets as raw file for example in Microsoft EXCEL and to process later on. To do this
please use assistant for text conversion of EXCEL .
As separator please choose the semico-
lon.
