PLC Hardware Configuration 23
Input
DB This receives the Genius bus parameters (via a variable of “user
defined type” G_Bus). Note that the parameters are configured
using the function blocks derived from either INIT_GB00 or
INIT_GBnn.
Output
PNCST Provides a copy of the status information for the associated
PROFINET Controller module.
A_PSD Provides a copy of the Genius Communication Gateway’s PROFINET
Status Data from Bus A.
B_PSD Provides a copy of the Genius Communication Gateway’s PROFINET
Status Data from Bus B.
DSB_A Provides a copy of the Genius Communication Gateway’s Genius
Status Data for all Configured Genius devices on Bus A. (This is like
the Device Status Bits provided by a Genius Bus Controller.)
DSB_B Provides a copy of the Genius Communication Gateway’s Genius
Status Data for all Configured Genius devices on Bus B.
CSB: Provides device connection status for all configured Genius devices
on the dual bus pair. (Each bit is latched ON by the rising edge of
either of the corresponding Bus A or Bus B Genius Status bits. The bit
is unlatched if both Bus A and Bus B Status Bits are OFF for a period
greater than the default timeout period.)
Other DBUS Functionality
Alarms Posted in PLC Fault Table
LOD An internal function that posts Loss-of-Device if the device is not
attached to either Bus A or Bus B, and the default timer has expired.
The time-stamped message appears in the PLC Fault Table.
AOD If the device has been offline, this internal function posts Addition-
of-Device if the Genius device successfully logs onto either Bus A or
Bus B. The time-stamped message appears in the PLC Fault Table.
Real-time View of Genius Devices on Dual Busses
Device Status Bits Zoom into the block to observe the current connection status for all
configured Genius devices on the dual bus pair. Four rungs display
the device status on Bus A and Bus B. The index inside the brackets
correspond to the Genius Serial Bus Address. Figure 30
demonstrates the logic for monitoring SBA 0 through 7, so it needs
to be expanded to cover the entire bus.
