C4 I/O Totaliser

C4.1

FB4 Totaliser 1

Set function of Totaliser _

_ stands for 1, 2, 3 (= Totaliser 1, 2, 3)

C4.2

FB5 Totaliser 2

C4.3

FB6 Totaliser 3

C4._.1

Totaliser Function

Select:

Absolute Total (counts positive and negative values) /

Incremental Total (counts only the positive values) /

Decremental Total (counts only the negative values) /

Stop Totaliser (totaliser is stopped, no counting) /

All As Positive (neg. input will be multiplied with -1.0) /

All As Negative (pos. values will be multiplied with 1.0)

C4._.2

Measurement

Select:

Mass Flow / Volume Flow / Conc. mass flow 1 / Conc. mass flow 2 /

Conc. volume flow 1 / Conc. volume flow 2

C4._.3

Preset Value

Predefines a threshold (using high low limit value of the totaliser affected;

the THRESHOLD bit will be set in the long status information bytes of the

interface if the actual value of the totaliser is outside these limits. This can

be also used for a status output.

C4._.4

Reset Totaliser

The current value of the totaliser can be set to zero.

Select: No / Yes (Reset Totaliser 1…3)

C4._.5

Error Behaviour

Defines the behaviour of this function block in case of errors.

Select: hold meas. value / ignore error / stop totaliser

hold meas. value:

hold meas. value: Totalization is continued based on the last incoming value

with good status before the first occurrence of bad status.

ignore error:

ignore error: Totalization is continued using the input values despite the bad

status. The status is ignored.

stop totaliser:

stop totaliser: Totalization is stopped during occurrence of bad status of

incoming values.

C4._.6

Information

Serial no. of the I/O board, software version no. and production date of the

circuit board will be displayed
