PROFIBUS DP interface for IS1+
3.5 HART variables
In addition to the analogue process value, HART field devices offer the option of digitally reading up to four
process variables (HART variables HV) from the transmitter.
IS1+ offers the option of mapping such HART variables to the cyclic input data area of PROFIBUS DP.
Optionally, no HART variables, four or eight HART variables of an IS1+ HART module (AIMH, AUMH, UMH,
AOMH) can be transmitted in addition to the cyclic data.
This can be selected optionally when configuring a field station via the GSE file, IS1 DTM or in IS Wizard :
Supply of HART devices using Analog Universal Module AUMH 9468/3x and UMH 9469
Each channel of an AUMH can be parameterized as analog input for HART sensors or as analog output for
HART actuators. The supply of HART sensors and HART actuators is different and will be switched too.
For communication with a HART sensor the channel shall be parameterized as ´Input´.
For communication with a HART actuator the channel shall be parameterized as ´Output´.
In a non-parameterized state the channels of an AUMH are in the position ´Output´ and HART
communication is possible with HART actuators only.
