4.8 Installing I/O Modules in the Controller
Each Pointe Controller application will differ in the number and type of I/O
modules, the operator panels used (if any) and how the devices must be
distributed. The modular design of the Pointe Controller system allows you to mix
and match to meet your exact application requirements.
System configuration entails an early process of defining exactly what type and
quantity of I/O you need at each location. If operator interaction, alarm
annunciation, or status display are required at the various points, the appropriate
operator panel should be chosen. Once that is done, you can custom tailor your
controllers by selecting and installing standard I/O modules in your Pointe
Controller base units and snapping the appropriate operator panel onto each.
4.8.1 Slot Numbering
Each module will occupy one slot in the controller base. Each slot position is
numbered as shown below. The slot number will provide a reference to your
application program for selecting the appropriate module for each particular
operation.
Slot numbering is simply left to right, starting with slot number 0.
