This chapter describes diagnostic functions that provide information but not an output signal.
10.6.1 Read totaliser values
For the totalisers Vol.1 and Vol.2, the following values can be read at any time:
• current volumetric flow quantity (= consumed quantity since the last reset).
• consumed quantity before the last reset.
• time in minutes since the last reset.
For the totaliser Vol.L, the following values determined during the entire operating time can be read at
any time:
• volumetric flow quantity in preferred direction (= positive flow direction).
• volumetric flow quantity in non-preferred direction (= negative flow direction).
