Bit Error Status Manipulated
by
Unit operation
0 (Not used.) --- --- ---
1 Transceiver echo test error
ON Unit ON if an error occurred during the self diagnostic
testing after the Unit was turned ON or reset.
OFF Unit OFF if the self diagnostic testing after the Unit was
turned ON or reset was normal.
2 IP address setting error
ON Unit ON if any of the following conditions apply to the IP
address.
• All bits in the host ID are 0 or 1.
• All bits in the network ID are 0 or 1.
• All bits in the subnet ID are 1.
• The IP address begins with 127 (0x7F)
OFF Unit OFF when the IP address is normal.
3 IP address table error
ON Unit On if the IP address table information is incorrect.
OFF Unit OFF when the IP address table is normal.
4 IP router table error
ON Unit ON if the IP router table information is incorrect.
OFF Unit OFF when the IP address table is normal.
5 (Not used.) --- --- ---
6 Routing table error
ON Unit ON if the routing table information is incorrect.
OFF Unit OFF when the routing table is normal.
7 Transceiver error
ON Unit ON when the transceiver cable is disconnected, the
transceiver is not receiving power, or the transceiver is
defective. Once this bit turns ON, it will not turn back
OFF even if the transceiver status returns to normal.
OFF Unit OFF when the transceiver is normal.
8 Internode Test Flag
ON Unit ON during internode testing.
OFF Unit OFF while internode testing is stopped.
9 to 13 (Not used.) --- --- ---
14 Address disagreement
ON Unit ON if the remote IP address is set to automatic
generation but the local IP address host number and
FINS node number do not agree.
OFF Unit OFF under all other circumstances.
15 EEPROM error
ON Unit ON if an error has occurred in the EEPROM memory.
OFF Unit OFF when the EEPROM memory is normal.
