Inverting analog inputs
“
E1
”
/
“
E2
”
After programming the signal or sensor type, an inversion of the inputs can be carried out.
IO Setup
Factory setting for Inverting inputs =
“
OFF
”
(if input activated) (signal: 0 - 10 V, 0 -
20 mA, 4 - 20 mA).
For activation using inverted default signals or sensors with inverted output signals
proportional to the measurement range, switch inverting to
“
ON
”
(Signal: 10 - 0 V, 20 -
0 mA, 20 - 4 mA).

Bus mode
After programming the signal or sensor type, the raw value (0-32767) of an analog sensor input can
be written in a Holding Register (h9000 for E1 and h9001 for E2) with the bus mode activated.
The connection is made at the MODBUS RTU Slave interface. Connecting terminals: A (D+), B (D-).
IO Setup
The bus mode of the inputs is set to
“
OFF
”
at the factory.
With activated bus mode, the raw values can be written accordingly into the Holding
Registers, addresses h9000 and h9001 for
“
E1
”
and
“
E2
”
.
