Functionality
Resource Block The Resource Block contains all
the data that uniquely identify
the device. It is an electronic
version of a nameplate of the
device.
1 0 - Enhanced
Analog Input
Block
The AI Block receives the
measuring data from the Sensor
Block (selectable via a channel
number), and makes the data
available to other blocks at its
output.
2 3 25 ms Enhanced
Discrete Input
Block
The Discrete Input Block receives
a discrete value (e.g. indicator
that measuring range has been
exceeded) and makes the value
available for other blocks at the
output.
1 2 20 ms Standard
Multiple
Analog Output
Block
The Multiple Analog Output
Block is used to transmit analog
values from the bus to the device.
1 0 20 ms Standard
Multiple
Discrete
Output Block
The Multiple Discrete Output
Block is used to transmit discrete
values from the bus to the device.
1 0 20 ms Standard
PID Block The PID Block is used as a
proportional-integral-derivative
controller and can be used
universally for closed-loop-
control in the field. It enables
cascade mode and feedforward
control.
1 1 25 ms Standard
Arithmetic
Block
The Arithmetic Block is designed
to permit simple use of popular
measurement math functions.
The user does not have to know
how to write equations. The
math algorithm is selected by
name, chosen by the user for the
function to be performed.
1 1 25 ms Standard
Signal
Characterizer
Block
The Signal Characterizer Block
has two sections, each with an
output value that is a non-linear
function of the input value. The
non-linear function is generated
by a single look-up table with 21
arbitrary x-y pairs.
1 1 25 ms Standard
Input Selector
Block
The Input Selector Block
facilitates the selection of up to
four inputs and generates an
output value based on the
configured action. This block
normally receives its inputs from
AI Blocks. The block enables the
selection of maximum, minimum,
average and ‘first good’ values.
