6.3 TYPICAL CONFIGURATION SETTINGS
The Tables below list some typical configuration settings for the 9780 FSK PLC. Note that these
settings are typical, and are not standard settings. Each RFL 9780 application is unique and should be
carefully evaluated by a knowledgeable Engineer. Normally, when a unit is shipped from RFL it is
shipped configured for the user's application. If, however, RFL is not aware of application specifics,
the system will be supplied with the typical settings. RFL Sales and Customer Support personnel are
always available to answer questions or assist in configuring a system.
