Relay Connected Field Device Impedance Outside Of Acceptable Range; Peer To Peer Communication Failure Code; Peer To Peer Communication Compatibility Mismatch: Ydoa - GE Mark VIeS System Manual

179-184
Description Relay [ ] connected field device impedance outside of acceptable range
Possible Cause A connected load does not fall within published impedance limits for TRLY__D-specific terminal
boards.
Solution
• Clear the voter disagreements.
• Check for field wiring open or short circuits.
• Check the attached load to ensure that impedance is within the published limits for TRLY__D. Refer to the terminal
board help documentation.
• Check TRLY input power.
• Replace TRLY__D.
191
Description Config Mismatch: TRLY__F terminal board is configured for SIMPLEX redundancy
Possible Cause The TRLY__F board is connected to an I/O pack that is configured as simplex. Due to the redundant
nature of the TRLY__F terminal board, a TMR I/O pack module configuration is required.
Solution From the ToolboxST application, configure the I/O pack redundancy as TMR. Build and download a new
configuration.
192
Description Peer to Peer Communication Failure Code [ ]
Possible Cause PGEN peer-to-peer communication for the PLU function has been lost. Refer to the PGEN
documentation for a description of peer-to-peer communication.
Solution
• From the ToolboxST application, select None for I/O Module Trip From as the source for a trip if the PLU function is
not used. Build and download the parameters.
• If a PGEN is used as a source for I/O Module Trip From then check the online status of the PGEN, and correct this if it
is not online.
• If other communication diagnostic alarms are active, check for issues with network cables, switches, and such.

Description Peer to Peer Communication Compatibility mismatch: YDOA [ ], Received Message [ ]
Possible Cause The firmware revision of PGEN used for the source of the PLU trip is not compatible with the YDOA
firmware revision.
Solution Upgrade the PGEN and YDOA to the latest firmware revision with the ControlST software suite, and download
the firmware and parameters to both I/O packs.
