SETTOT_TOTAL module
The module combination SETTOT_TOTAL (slots 2 to 4) consists of the functions SETTOT
and TOTAL.
With this module combination:
• The totalizer can be controlled via the automation system (SETTOT).
• The totalizer value, is transmitted, including the status (TOTAL)
SETTOT function
In the SETTOT function, the totalizer can be controlled via control variables.
The following control variables are supported:
• 0 = Totalize (factory setting)
• 1 = Reset totalizer (the totalizer value is reset to 0)
• 2 = Accept totalizer preset
!
Note!
After the totalizer value has been reset to 0 or set to the preset value, the totalizing
continues automatically. The control variable does not have to be changed to 0 again to
restart totalizing.
Stopping totalizing is controlled in the SETTOT_MODETOT_TOTAL module via the
MODETOT function. →  109
