Ppda Power Distribution System Feedback - GE Mark VIeS System Manual

10.2 PPDA Power Distribution System Feedback

10.2.1 Compatibility
At the heart of the core PDM is the PPDA I/O pack. This I/O pack is designed to accept inputs from up to six different power
distribution boards, condition the signals, and provide a dual redundant Ethernet interface to the controllers. The feedback is
structured to be plug and play meaning the PPDA is able to check the power distribution boards that are wired into it using
electronic IDs. It uses this information along with ToolboxST configuration to populate the IONet signal space output with the
correct feedback signals from connected boards.
The PPDA I/O pack is hosted by the JPDS or JPDG 28 V dc control power boards on the PDM. It is compatible with the
feedback signals created by JPDE
The following are PPDA I/O pack versions and minimum software requirements:
• The PPPDAH1B contains BPPC processor board that is supported in the ControlST software V04.07 and later.
• With PPDAH1B and ControlST software V05.02 or later, the PPDA can be used to send power distribution feedback data
to the Mark VIeS Safety controller.
• With ControlST V5.02 or later, the PPDA no longer supports a board-mounted accelerometer. Be aware if upgrading
from a previous version, the ToolboxST application does not identify existing use of connected accelerometer variables.

The Power Distribution Diagnostic Feedback I/O pack (IS420PPDAH1B) produces
system feedback signals for power bus voltages, branch circuit status, ground fault
detection, and bulk power supply health from the connected core distribution board(s).
The I/O pack accepts inputs from up to a maximum of six power distribution boards or
up to six sets of feedback signals. It conditions the board feedback signals and provides a
dual redundant Ethernet interface to the controllers. The PPDA feedback is structured to
be plug and play, using electronic IDs to determine the power distribution boards wired
into it. This information is then used to populate the IONet output providing correct
feedback from connected boards.
The PPDA I/O pack is hosted by the JPDS or JPDG 28 V dc control power distribution
board. Additional boards are connected using 50-pin ribbon cable jumpers that are wired
pin 1 to pin 1. Each board contributes one feedback group to the PPDA. The PPDA I/O
pack is compatible with the feedback signals created by the JPDE.
