The EL31xx terminals offer two different process data per analog channel for transmission: the analog value
Value (16 bit) and status information (16 bit). As with individual channels, the transmission of individual
status information can be deactivated in the ProcessData tab; these changes are effective after activation
and an EtherCAT restart or reload.
There is a choice of 2 types of process data in the EL31xx:
• Standard: standard setting, Value (16 bit) and status information (8 or 16 bit) are transmitted per
channel
• Compact: only the Value (16 bit) is transmitted per channel
The settings are described below, taking the EL3102 (2 channels, ±10V) as an example. The data apply to
TwinCAT 2.11 from build 1544 onward and XML revision from EL31xx-0000-0016 onward.

The plain text display of the bit meanings of the status word is particularly helpful not only in commissioning
but also for linking to the PLC program.
By right-clicking on the status variable in the configuration tree (A), the structure can be opened for linking
(B).
In order to be able to read the bit meanings in plain text in the online display (C), the button
Fig. 111: Show sub variables
can be used to show all subvariables, including the structure content of the status word, see Fig. Display
