Resetting totalizer 1 automatically
By means the Analog Alarm Block
With the aid of the Analog Alarm and Discrete Output Block, totalizer 1 in the DP_Flow
Transducer Block can be reset automatically.
The DP_FLOW Transducer Block is connected to an Analog Input Block by means of the
Channel/CHANNEL parameter (Channel/CHANNEL = 6). In the Analog Alarm Block the
High High Limit/HI_HI_LIM parameter is used to set a limit value at which the totalizer
should be reset to zero. As soon as this limit value is overshot, the Analog Alarm Block
transmits an alarm value to the downstream Discrete Output Block. The latter changes its
output from 0 to 1 and thus resets the totalizer in the DP_FLOW Transducer Block to 0. The
output of the Analog Alarm Block changes back to 0.
