TOTAL function
For a description of the TOTAL function, refer to TOTAL module
Data structure of the SETTOT_TOTAL module combination
SETTOT_MODETOT_TOTAL module
The module combination SETTOT_MODETOT_TOTAL (slots 9 to 11) consists of the functions
SETTOT, MODETOT and TOTAL.
With this module combination:
• The totalizer can be controlled via the automation system (SETTOT).
• The totalizer can be configured via the automation system (MODETOT).
• The totalizer value is transmitted including the status (TOTAL)
SETTOT function
For a description of the SETTOT function, refer to SETOT_TOTAL module.
MODETOT function
In the MODETOT function, the totalizer can be configured via control variables.
The following settings are possible:
• 0 = Balance (factory setting), calculates the positive and negative flow portions
• 1 = calculates the positive flow portions
• 2 = calculates the negative flow portions
• 3 = Totalizing is stopped
!
Note!
For the calculation of the positive and negative flow portions (control variable 0) or the negative
flow portions only (control variable 2) to be carried out correctly, the option BIDIRECTIONAL must
be active in the MEASURING MODE (6601) function.
TOTAL function
For a description of the TOTAL function, refer to TOTAL module
Data structure of the SETTOT_MODETOT_TOTAL module combination
Example of using the SETTOT_MODETOT_TOTAL module
If the SETTOT function is set to 1 (= reset the totalizer), the value for the aggregated total is reset
to 0.
If the aggregated total of the totalizer should constantly retain the value 0, the MODETOT function
must first be set to 3 (= totalizing is stopped) and then the SETTOT function must be set to
1 (= reset the totalizer).
