Some points of importance pertaining to PointScan/100 and /200 Series systems:

The tab used [Discrete or Analog] depends on the type of module that you are configuring.

For information on how to set the parameters, click on the button.

Disable all unused channels.

You can select a unique tag name for each of channel. These tag names will be used by

KEPServer and DASYLab to identify the channels when creating your final program.

Do not change the I/O address. This is the standard addressing scheme used by the
Modbus protocol. These addresses will be used by KEPServer to access the data from the

PointScan modules.

Each PointScan module can have different selections under the “features” column. Refer to
your specific type of PointScan module for available features. You can select or change any

available features on a per channel basis.

The Range column can be set on a per channel basis. Pick the measurement range that is

best suited for your particular application.

There are PointScan modules that are capable of several different scan rate settings. You

can select the module scan rate setting that is most appropriate for your application. It is

recommended that you select the same scan rate for all modules in your system. You
should configure the modules for the fastest sample rate that you ever expect to need and

then you can use a method in DASYLab to discard readings to effectively create a lower

sample rate for the modules of your choice.

Scaling is typically done using KEPServer or DASYLab. You should not make any changes

under the Scaling Parameter tab in IOToolKit.

It is important to note that all thermocouple inputs are in Engineering Units (EU)
of degrees Celsius or Fahrenheit, depending on the “Temperature Reporting”

selection. If you select 0.1°C or 0.1°F the reading generated by the module will

be a whole number 10 times greater than the actual value. If this is the case you
will need to scale down the value by a factor of 10 in KEPServer or DASYLab.

All voltage and current inputs are in raw A/D converter counts. Therefore, the
voltage and current inputs must be scaled to Engineering Units in KEPServer or

DASYLab by converting them to floating point numbers.
