8-2. Output
Output signal
Foundation Fieldbus™ H1, IEC 61158-2
FDE (Fault Disconnection Electronic) = 0 mA
Data transmission rate: supported baud rate = 31.25 kBit/s
Signal coding = Manchester II
Compliance with ITK 6.0.1
Output data:
Available values via AI blocks: temperature (PV), temp sensor 1 + 2, terminal temperature
LAS (link active scheduler), LM (link master) function is supported:
Thus, the head transmitter can assume the function of a link active scheduler (LAS) if the
current link master (LM) is no longer available. The device is supplied as a BASIC device.
To use the device as an LAS, this must be defined in the distributed control system and
activated by downloading the configuration to the device.
In accordance with IEC 60079-27, FISCO/FNICO
