Instruction Manual Section 12: Profibus Communications

Section 12.0 Profibus Communications
12.1 General
The 56 can communicate using Profibus DP-V1 by purchasing a 56 with a Profibus
communication board installed (model code 56-PC-02-DP), or by adding a Profibus
communications board to the standard 56 with HART communications.
The standard HART 56 analyzer can be converted to Profibus DP by adding a Profibus board.
There are two different Profibus boards for the 56, which must be chosen to be compatible with
the main board software version of the 56.
• If the 56 software version begins with a 2 (2.XX), Profibus board PN 24285-02 should be chosen.
• If the 56 software version begins with a 1 (1.XX), Profibus board PN 24285-01 should be chosen.
A 56 with Profibus communications retains all the analog and discrete functionality of the
standard HART 56 transmitter. The four 4 to 20 mA analog outputs can be configured as analog
outputs or PID control outputs.
The four discrete relay outputs can be configured for concentration control (high/low alarms
with or without a delay timer), event based activation, timer based activation, or TPC (Duty
Cycle/ Pulse Width Modulation) control.
12.2 Profibus Features
As outlined in the Device Description Data Field (GSD), the 56 has the following Profibus DP-
V1 identification and capabilities:
