N feedback data array In anticipation of the new value from the drop the DLAN L program block updates the setpoint in the feedback array with the new value This provides a convenient mechanism for the user s PLC logic to determine when to set a particular setpoint bit Whenever the setpoint value and the corresponding feedback value are different the setpoint value needs to be sent to the drop The user logic can accomplish this by setting the appropriate setpoint bit Note that a temporary interruption of communication between the DLAN Interface module and the drop could occur after the DLAN feedback array was updated but before the drop actually changed its data page In this case the interruption would cause a discrepancy between the DLAN feedback array and the data page in the drop When communication is restored the current value from the drop s data page will be copied to the feedback array If the user program now compares the setpoint to the corresponding feedback value the difference will be detected and the appropriate setpoint bit can be set in order to update the page data in the drop Feedback Signals Feedback data is copied to a PLC global R memory block specified in the DLAN L block user configuration data as it arrives from DLAN drops The user program may examine this data at any time Link Presence Signals Periodically all devices on the LAN network report their presence The DLAN Interface program keeps a record
