Chapter 6: Ladder Program Examples 55

Programming Examples

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

programming requirements.

Initial Programming

Figure 5.1 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

our web site: www.spectrumcontrols.com.
