4.1 Process interface
4.1.1 Process interface Xi 80/410
The Xi 80/410 is equipped with an integrated process interface
(cable with terminal block included in scope of supply), which
can be programmed via the software as a direct analog input
(AI), as a direct analog output (AO) in order to control the
process or as an RS485 interface
1)
. The signal level is 0-10 V
for AI and 0/4-20 mA for AO.
The process interface can be activated via the software choosing the following options:
Emissivity, ambient temperature, reference temperature, uncommitted value, flag control, triggered recording,
triggered snapshots, triggered line-scanner, triggered event grabber, reset peak-/valley-hold, switch temperature
range
Main measure area, measure area, internal temperature, flag status, recording status, line scan status, alarm,
frame sync, fail-safe, external communication

Direct out- and inputs are not available while using the RS485 interface
