to the receiving module every 10 seconds. The receiving module will then output the
pulse count over the configured update time, i.e.10 seconds

Analog Inputs

The Analogue Inputs have more configurable
options and this is mainly due to each input also
having a set point assigned to them. Analogue
inputs can also be used as Voltage inputs by
selection of dip switches in the WI-I/O 9-U2
modules.

The WI-I/O 9-U2 Analog inputs have the
following configuration parameters.

Name

The inputs can be named to help with

configuration or use the default, up to 30 characters
including spaces.

Filter (sec)

The Filter time Constant is the time the

analog takes to settle on a step changed of an analog
value. By default, all the inputs except the Pulse Rates
have a Time constant of 5 seconds. Pulsed input rates
are not filtered.

Scaling

The software shows the input scaling in either

‘Low-High Values’ or ‘Zero-Span values’. These
variables will change the Scale of the Analog Inputs.

Low

– The low Engineering value for the Input

High

– The high Engineering value for the Input (mA, V, Hz, etc)

Zero

– Starting Value (counts) when measured value is zero

Span

– Number of counts per measured value (mA, V, Hz, etc)

The Analog is a linear scale with an overall raw range of 8192 to 49152 decimal (Total =
40960). The input Engineering range can have many different forms i.e. 0-20mA, 0-5V,
or 0-1000Hz which is why the zero and span can be scaled to give the correct value.

Lower & Upper Setpoints

Are the upper and lower control point values that will be

used to turn on and off the Analog Setpoint digital signals located at register 10009

10020.

Note: Setpoint values are entered in the scale of the input, i.e. Analog input 1-4
will be in mA, Analog inputs 9-12 will be volts, etc.
