Information regarding the function
channel MesR
3.1 Usage of the function channel MesR
Thanks to the function channel MesR
it is possible to use the
measured value of a measuring channel that is marked
with
function abbreviation *R
in its channel designation throughout all
measuring circuit boards. It is also possible to use measured val
of different measuring circuit boards in one
arithmetic channel
The function channel MesR can only be configured in
a V5 or V6
plug.
Arithmetic channels that shall use the measured values of the
function channel MesR can only be configured in a V5 or
V6 plug
The function channel MesR
and the measuring channel marked with
the channel abbreviation *R
must not be located on the same
measuring circuit board.
The sensor, in which the function channel MesR is set,
must be on a
measuring circuit board featuring a higher measuring circuit board
address than the sensors,
to which the function abbreviation
be designated.

3.2 Example regarding relative humidity
in a climatic
chamber
In the present Supplementary Instruction Manual, the following
example will be described:
The relative humidity shall be calculated by the arithmetic c
tdUw.
To do so, the dew point from a measuring channel featuring the
range td will be used. The function abbreviation *R
will be assigned to
this measuring channel.
The arithmetic channel tdUw
will be adjusted on a measuring circuit
board featuring a higher measuring circuit board address.
The arithmetic channel tdUw
receives the measured data from the
function channel MesR. The function channel MesR
receives the
measured data from the measuring channel featuring
the function
abbreviation *R.

The update rate of the function channel
The measured value of the function channel MesR is
updated approximately every
two seconds. The update rate depends on the number of active measuring
channels and on the storage cycle (scanning cycle respectively output cycle).

The function channel is used to acquire operands from other
measuring circuit boards. The function channel must
be set up in a
sensor with a V5 or a V6 plug that is connected to the measuring
circuit board,
to which the sensor with the arithmetic channel is
connected.
