Input signal Input data: The head transmitter is able to receive a cyclic value and its status sent by a master via
PROFIBUS
®
PA. That value and status is represented and can be read acyclically.
10.0.2 Output
Output signal • PROFIBUS
®
PA in accordance with EN 50170 Volume 2,
IEC 61158-2 (MBP), galvanically isolated;
Amendment 2 “Condensed status and diagnostic messages”
Amendment 3 “Identification and Maintenance Functions”
• FDE (Fault Disconnection Electronic) = 0 mA
• Data transmission rate: supported baud rate = 31.25 kBit/s
• Signal coding = Manchester II
• Output data:
Available values via AI blocks: temperature (PV), temp sensor 1 + 2, terminal temperature
• In a control system the head transmitter always operates as a slave and, dependent on the
application, can exchange data with one or more masters.
• In accordance with IEC 60079-27, FISCO/FNICO
Breakdown information Status message in accordance with PROFIBUS
