C5 I/O PROFIBUS

I/O PROFIBUS

Using the menu functions mentioned below you will be able to control

basically the five analog input blocks of this PROFIBUS device. These eights

menus are identical so they are grouped together and their functions are

described in one go.

C5.1

FB1 Analog Inp.

There are 8 analog input blocks.

_ stands for the 8 analog input blocks: FB1 (_ = 1), FB2 (_ = 2), FB3 (_ = 3),

FB7 (_ = 4), FB8 (_ = 5), FB9 (_ = 6), FB10 (_ = 7), FB11 (_ = 8),

C5.2

FB2 Analog Inp.

C5.3

FB3 Analog Inp.

C5.4

FB7 Analog Inp.

C5.5

FB8 Analog Inp.

C5.6

FB9 Analog Inp.

C5.7

FB10 Analog Inp.

C5.8

FB11 Analog Inp.

C5._.1

Measurement

Select measurement value for the analog input blocks:

Volume Flow / Mass Flow / Density / Temperature / Concentration 1 /

Flow Velocity / Electronics Temp. / Supply / Concentration 2 /

Conc. volume flow 1 / Conc. mass flow 1 / Conc. volume flow 2 /

Conc. mass flow 2 / Sensor Average / Sensor Deviation / Drive Level /

Tube Frequency / Strain 1 / Strain 2 / 2 Phase Signal

C5._.2

Time Constant

Set time constant for this function block (_).

C5._.3

Error Behaviour

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

Select: hold value / ignore error / replace value

hold value:

hold value: Last valid OUT value stored will be used as OUT value.

ignore error:

ignore error: OUT has the wrong calculated value and status "Bad" as

calculated.

replace value:

replace value: The "replacement value" will be used as OUT value.

C5._.4

Replacement Value

Available, if the error behaviour "Replace Value" is selected. Defines the

value that replaces the measured value at this function block in case of an

error.
