8.2 Sample Circuits
This section describes four sample circuits:
- Sample circuit for accessing slave contact inputs and outputs;
- Sample circuit for disabling automatic address assignment function;
- Sample circuit for detecting invalid slaves and checking ASi system error alarms;
- Sample circuit for changing slave address
The sample programs assume that the ASi Master module is mounted in slot 4, and 62
slaves are connected. Modify the sample program as required to suit your application
before use

TIP
Signal names have been assigned to devices and coded in the given sample programs but you could
also write a program using just device names. Using signal names however improves readability and
maintainability.
