Message
Description
RECIP AXIS IN WRONG PLANE
The reciprocation axis specified in a G81 or a G81.1 programming block is not in the currently
selected plane.
RECIP AXIS NOT PROGRAMMED
No reciprocation axis was specified in a G81 or a G81.1 programming block.
RECIPROCATION NOT STOPPED
An attempt was made to deactivate the current part program while reciprocation is still active.
You must deactivate reciprocation before deactivating the current part program.
REMOTE I/O COMMON RAM FAULT ON RESET
The RIO module tests the common RAM after reset and detects an error. The Interboard
Communications Fault LED is turned ON.
REMOTE I/O CTC CHIP TEST FAULT
The RIO module tests the CTC chip after reset and detects a fault. The Processor Fault LED is
turned ON.
REMOTE I/O DENIED COMMON ACCESS ON RESET
The RIO module was denied access to CRAM for more than 1 second after reset. The
Interboard Communications Fault LED is turned ON.
REMOTE I/O EPROM INTEGRITY FAULT
The checksum test over the RIO program area in the EPROM chip found a fault. The Processor
Fault LED is turned ON.
REMOTE I/O INCORRECT USER BT DATA AMOUNT
The RIO module attempted to read a block of data from one of the user output block transfer
data buffers in common RAM and found the word count of the data to be outside of the range of
1 to 64. The Interboard Communications Fault LED is turned ON.
REMOTE I/O INITIALIZATION ERROR
Remote I/O hardware or network has failed to initialize. Cycle power to try to restart or check
remote I/O hardware (9/290 only).
REMOTE I/O INTERNAL RAM FAULT
The RIO module tests its internal RAM chip after reset and during operation. A fault has been
detected. The Processor Fault LED is turned ON.
REMOTE I/O INTERRUPT HARDWARE FAULT
The RIO module detects that its CPU was not interrupted by any expected external interrupts.
This condition indicates a problem in recognizing interrupts. The Processor Fault LED is turned
ON.
REMOTE I/O INVALID RACK ADDRESS SET UP
The RIO module’s rack address is illegal. This fault is the result of the user setting the rack
address, via the dip switches, to an invalid rack size and/or starting module group number.
REMOTE I/O INVALID USER BT DATA CHECKSUM
The 16-bit 2’s complement checksum calculated by the RIO module using data from a user
output block transfer data buffer does not match the checksum placed in the buffer by the user
device. The Interboard Communications Fault LED is turned ON.
REMOTE I/O INVALID USER DATA CHECKSUM
The 16-bit 2’s complement checksum calculated by the RIO module using data from the user
output data table in common RAM does not match the checksum placed by the user in the user
output data table in common RAM. The Interboard Communications Fault LED is turned ON.
REMOTE I/O MISSING USER OPERATIONAL CODE
The RIO module did not detect the user operational code after reset. This fault is displayed
when the RIO module does not detect the user operational code in the user status register in
common RAM within 100ms after the RIO module has set its operational code and released
control of common RAM back to the user device. The Interboard Communications Fault LED is
turned ON.
REMOTE I/O RIO DENIED COMMON RAM ACCESS
The RIO module was denied access to CRAM for longer than the specified interval. The RIO
module failed to gain access to common RAM after attempting for the Accessing Time-out time
period. The time-out is due to either the user device maintaining access for more than the
Accessing Time-out interval. or to a hardware failure. The Interboard Communications Fault
LED is turned ON.
REMOTE I/O SERIAL COMMUNICATIONS FAULT
The RIO module cannot communicate with the PLC processor. Either the PLC processor’s
power is OFF, the blue hose is not connected, or the PLC processor is in Edit mode.
REMOTE I/O SIO CHIP TEST FAULT
The RIO module tests the SIO chip after reset and detects a fault. The processor fault LED is
turned ON.
REMOTE I/O UNABLE TO FIND BT DATA BUFFER
The RIO module was unable to detect the user block transfer data buffer. The interboard
communications fault LED is turned ON.
REMOTE I/O UNRECOVERABLE ERROR
Remote I/O hardware or network has catastrophic failure. Cycle power to try to restart or check
remote I/O hardware (9/920 only).
