Note:
It will be necessary to enter the numerical code (factory setting: 53) before altering
device functions, numerical values or factory settings
→ Page 68.
The following steps have to be carried out one after the other:
1. Check the hardware write protection:
BASIC FUNCTION (G)
→ PROFIBUS-DP/-PA (GBA) → CONFIGURATION (610)
→ WRITE PROTECT (6102)
2. Enter the tag name:
BASIC FUNCTION (G)
→ PROFIBUS-DP/-PA (GBA) → CONFIGURATION (610)
→ TAG NAME (6100)
3. Assign a bus address if this has not already been effected via the corresponding
miniature switches (see Page 84):
BASIC FUNCTION (G)
→ PROFIBUS-DP/-PA (GBA) → CONFIGURATION (610)
→ BUS ADDRESS (6101)
4. Configuring the system unit of the volume and mass flow:
– Via the function group “System unit”: MEASURED VARIABLES (A)
→ SYSTEM
UNITS (ACA)
→ CONFIGURATION (040) → UNIT MASS FLOW (0400) → UNIT
MASS (0401)
→ UNIT VOL....
– The system unit which has been configured will become effective in the control
system once the function SET UNIT TO BUS has been activated: BASIC FUNC-
TION (G)
→ PROFIBUS-DP/-PA (GBA) → OPERATION (614) → SET UNIT TO
BUS (6141)

Note:
The measured values are transmitted in system units - as described in the table on
Page 93 ff. - to the automation control system during the cyclic data exchange.
If the system unit of a measured value is changed using the local display, this will
not have an immediate effect on the output of the AI block and therefore will not
influence the measured value which is transmitted to the automation control
system.
The altered system unit of the measured value will only be transmitted to the auto-
mation control system once the “SET UNIT TO BUS“ function in block G (BASIC
FUNCTIONS)
→ PROFIBUS-DP/-PA (GBA) → OPERATION (614) → SET UNIT TO
BUS (6141) has been activated.
5. Configuration of the totalizers 1-3:
Promag 53 disposes of 3 totalizers. The following description provides an example
for totalizer 1.
– Selection of the process variables with the parameter CHANNEL e.g. volume
flow: BASIC FUNCTION (G)
→ PROFIBUS-DP/-PA (GBA)
→ TOTALIZER (613) → CHANNEL (6132)
– Entry of the required units for the totalizer:
BASIC FUNCTION (G)
→ PROFIBUS-DP/-PA (GBA) → TOTALIZER (613)
→ UNIT TOTALIZER (6133)
– Configuration of the totalizer (define totalizer status) e.g. for Totalizing:
BASIC FUNCTION (G)
→ PROFIBUS-DP/-PA (GBA) → TOTALIZER (613)
→ SET TOT (6134)
– Configuration of the totalizer mode e.g. for Balancing: BASIC FUNCTION (G)
→
PROFIBUS-DP/-PA (GBA)
→ TOTALIZER (613) → TOTALIZER MODE (6136)
