4.14.3 Offset adjustment via PLC interface force transducer channel 1
+ 2
An offset adjustment for all channels can be started via the PLC interface.
The handshake to start the offset adjustment via the PLC happens analog
to writing a test number.
Signal name Type:
Input "I" / Output "O"
Designation
E0 I Program number bit 0
E1 I Program number cycle
E5 I Offset adjustment external
A4 o Acknowledgement of program number 3
A5 o The device is ready for operation

Fig.10 External offset adjustment via PLC interface channel 1
With the end of the cycle (3) the external offset adjustment of the selected
channel is started. While the offset adjustment is running (maximum of 3
seconds per channel) the <Ready> signal is reset (4). After the adjustment
without error (5) the <Ready> signal is set again. The signal <External off-
set adjustment> (E5) must be reset again (6).
During an external offset adjustment a running measurement is interrupted.
If the error "Pre-selected channel not available" or the error "Offset limit ex-
ceeded" occurs, the signal <External offset adjustment> must be cancelled.
Then execute the offset adjustment anew.
