Port 1 Adapter 71 The communication card has detected a fault on the network.
(4)
Check DPI device event queue and
corresponding fault information for the
device.
Port 2 Adapter 72 The communication card has detected a fault on the network.
(4)
Port 3 Adapter 73 The communication card has detected a fault on the network.
(4)
Port 4 Adapter 74 The communication card has detected a fault on the network.
(4)
Port 5 Adapter 75 The communication card has detected a fault on the network.
(4)

1. If adapter was not intentionally
disconnected, check wiring to the port.
Replace wiring, port expander,
adapters, Main Control Board, or
complete Converter as required.
2. Check HIM connection.
3. If an adapter was intentionally
disconnected and the [Logic Mask] bit
for that adapter is set to “1,” this fault
will occur. To disable this fault, set the
[Logic Mask] bit for the adapter to “0.”
Port 2 DPI Loss 82 The DPI communication to a peripheral was lost.
(4)
Port 3 DPI Loss 83 The DPI communication to a peripheral was lost.
(4)
Port 4 DPI Loss 84 The DPI communication to a peripheral was lost.
(4)
Port 5 DPI Loss 85 The DPI communication to a peripheral was lost.
(4)
Port 6 DPI Loss 86 The DPI communication to a peripheral was lost.
