Earlier chapters explained how the tag configuration defines the way the
module operates. This chapter shows some basic programming which
controls the operation of the module. It also provides you with segments
of ladder logic specific to unique situations that might apply to your

Figure 8.1 illustrates some basic ladder logic commands which will allow
you to:
• program the initial configuration into the module
• copy data to user defined tags
• reset the module
• make on-the-fly configuration changes
• unlatch alarms
Additional ladder logic and configuration samples may also be found on
