REMOTE I/O COMMON RAMFAULT ON RESET The RIO module tests the common RAMafterresetanddetectsan error. TheInterboard
Communications FaultLED isturned ON.
REMOTEI/OCTC CHIPTEST FAULT T he RIO module teststhe CTCchip afterresetand detects afault. TheProcessorFaultLEDis
turned ON.
REMOTE I/O DENIEDCOMMON ACCESS ON RESET TheRIOmodulewasdenied access to CRAMformore than 1 secondafterreset. The
Interboard CommunicationsFaultLEDis turned ON.
REMOTE I/O EPROM INTEGRITY FAULT The checksumtestovertheRIOprogramarea intheEPROMchipfounda fault. The Processor
FaultLEDisturned ON.
REMOTEI/OINCORRECT USER BT DATA AMOUNT The RIO module attemptedtoreada blockofdata fromone of theuseroutputblocktransfer
data buffers in common RAMand found the word countofthe datatobe outside ofthe range of
1 to 64. The InterboardCommunications FaultLEDisturned ON.
REMOTE I/O INITIALIZA TION ERROR Remote I/O hardware or networkhasfailed to initialize. Cyclepowerto trytorestartorcheck
remoteI/O hardware(9/290 only).
REMOTEI/OINTERNAL RAM FAULT The RIO module testsits internalRAMchip afterresetand during operation. A faulthasbeen
detected. The ProcessorFaultLEDisturned ON.
REMOTEI/OINTERRUPT HARDWAREFAULT The RIOmoduledetects thatits CPU wasnotinterruptedby anyexpected externalinterrupts.
Thiscondition indicatesa problem in recognizinginterrupts. TheProcessor F aultLEDis turned
ON.
