Commissioning Proline Promag 55 PROFIBUS DP/PA
90 Endress+Hauser
Using the CHANNEL function (6123), you can determine the measured variable (e.g. volume
flow) to be cyclically transmitted to the PROFIBUS master (Class 1):
a. Select BASIC FUNCTION (G) PROFIBUS PA (GCA) FUNCTIONBLOCKS (612)
BLOCK SELECTION (6120).
b. Select the option ANALOG INPUT 1.
c. Select the function CHANNEL (6123).
d. Select the option VOLUME FLOW.
Possible settings:
6. Setting the measuring mode:
In the function MEASURING MODE (6601), select the flow portions to be measured by the
measuring device.
BASIC FUNCTION (G) SYSTEM PARAMETER (GLA) CONFIGURATION (660)
MEASURING MODE (6601) Selection of one of the following options:
– UNIDIRECTIONAL (factory setting) = only the positive flow portions
– BIDIRECTIONAL = the positive and negative flow components
7. Configuration of Totalizers 1 to 3:
The measuring device has three totalizers. The following example describes the configuration
of the totalizer using Totalizer 1 as an example.
Measured variable ID for "CHANNEL" function
VOLUME FLOW (factory setting AI function block 1) 273
MASS FLOW (factory setting AI function block 2) 277
The following measured variables are available when the additional "solids flow" software is installed
in the device (order option)
TARGET MASS FLOW 1164
% TARGET MASS FLOW 1165
TARGET VOLUME FLOW 1167
% TARGET VOLUME FLOW 1168
CARRIER MASS FLOW 1170
% CARRIER MASS FLOW 1171
CARRIER VOLUME FLOW 1172
% CARRIER VOLUME FLOW 1173
The following measured variables are available when the additional "advanced diagnostic" software is
installed (order option)
DEVIATION COATING 1 2341
DEVIATION COATING 2 2358
DEVIATION ELECTRODE POTENTIAL 1 2375
DEVIATION ELECTRODE POTENTIAL 2 2392
DEVIATION VOLUME FLOW 2419
DEVIATION NOISE VALUE 2443
!
Note!
If, when the PROFIBUS network configuration, the AI module was integrated in slot 1 or 5, the measured variable
selected in the CHANNEL function is transmitted cyclically to the PROFIBUS master (Class 1) for the respective
Analog Input function block 1 to 2 ä 99.
