Configuration; Software Operation And State Machine - Agilent Technologies TwisTorr 305 FS User Manual

Technical Information

Configuration

Before power-on the controller set the ProfiBus address by the 2 rotary switches.
Up to 126 different addresses (from 0 to 125) can be selected. The address value
sets by the 2 switches is expressed in hexadecimal notation, so value from 00 to 7D
are permitted; this setting is read by the interface during the power-on phase, so
any change of the switch position after the power-on is ignored.

Software Operation and State Machine

From the software point of view, the interface can be seen as two devices (one for
ProfiBus and the other for the internal link) linked together.
Each device has its own state machine to manage the device operation.
