8.2 Diagnosis history 10F3
hex
The object 10F3hex is implemented as ring memory into the
"Overwrite mode". The latest 20 diagnostic messages are
stored. Older messages are deleted.
The following table shows the structure of a diagnostic mes-
sage of the bus coupler for EtherCAT.

Installation
9.1 Connection instructions
Differential input and potential reference
For analog inputs, there are differential inputs without a refer-
ence to an external mass. Thus, note that the "Common Mode"
- the average value of the signals at the + and - input is not
higher compared to the internal mass U
P
GND than the values
specified in the technical data.
For the single-ended connection of 2- or 3-conductor sensors,
connect the "-" input with U
P
GND.
Cable and shielding
NOTICE
Electronic damages and measuring errors
Unshielded cables can cause that tolerance limits are easily
exceeded in an environment prone to interferences.
Always connect the analog sensors with shielded cables
twisted in pairs.
Connect the cable shielding to the functional earth immedi-
ately after entering the control cabinet. Route the cable with
its shielding up to the module. The signal cables should be
routed the shortest possible without shielding.
For the best connection directly in front of the module, the
shield connection set (R911173030) is provided together with
the busbar (R911173283).
