Promag 53 PROFIBUS DP/PA Commissioning
Endress+Hauser 97
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 DP (GBA) 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.
‣ Using the CHANNEL function (6133), you can determine the measured variable
(e.g. volume flow) to be cyclically transmitted to the PROFIBUS master (Class 1) as
a totalizer value:
a. Select BASIC FUNCTION (G) PROFIBUS DP (GBA) TOTALIZER (613)
SELECT TOTALIZER (6130).
b. Select the option TOTALIZER 1.
c. Go to the function CHANNEL (6133).
d. Select one of the following options:
– VOLUME FLOW (CHANNEL = 273, factory setting): the volume flow is
totalized.
– MASS FLOW (CHANNEL = 277): the mass flow is totalized.
– OFF (CHANNEL = 0): no totalizing, "0" is displayed as the totalizer value.
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 "batching" software is installed
(order option)
BATCH UPWARDS 1346
BATCH DOWNWARDS 1347
BATCH COUNTER 1348
BATCH SUM 1349
BATCHING TIME 1354
!
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. → 107
