Remote I/O Error Codes
Remote I/O Module
Remote I/O Head
Remote Drive Interface Head
0 CPU failed powerĆup diagnostic
1 EPROM failed powerĆup diagnostic
2 RAM failed powerĆup diagnostic
3 CTC failed powerĆup diagnostic
.3 CTC runtime failure
4 SIO port failed powerĆup diagnostic
5 DMA failed powerĆup diagnostic
.5 DMA runtime failure; message transmit timeout occurred
6 I/O device interface failure (Remote I/O Head and Remote Drive Interface
Head only)
6 Dual port memory failed powerĆup diagnostic (Remote I/O module only)
.6 Runtime I/O interface failure (Remote I/O Head and Remote Drive Interface
Head only)
7 Memory Management unit failed powerĆup diagnostic
(Remote I/O module only)
.8 or 8 Microprocessor on module did not attempt to go into run
(Remote I/O module only)
ăBad, missing, or wrong runbase EPROM,
ăBad power supply
ăInterference from another module
ăBad backplane
Try reĆseating the module
9 PIO port failed powerĆup diagnostic
A Invalid drop number. This occurs only if the drop number on the thumbwheel
switch is greater than 07.
b Watchdog timer failed powerĆup diagnostic
C Communication line failure. If the module is a master drop, no other drops are
functional on the network. If the module is a slave drop, it is not receiving any
messages from the master drop. This fault code is reset whenever the line
goes active.
d System (backplane) watchdog failed; a Processor module went down. Board
is operational but will not transmit or receive any data until the watchdog is
reset. (Remote I/O module only).
E Power failure. This code is normally present from the time that a low voltage is
detected until power is completely lost.
