z Bad coil used table: This error means that the coil used table does not match
user logic. Possible causes include:
1. This error is often seen when a program is altered offline by non-Modsoft users
and then reloaded. It may be neccesary to update the coil used table manually in
order to recover from this error.
2. The battery coil is not configured or configured in correctly. This error is not
uncommon if the program is being relocated from another PLC.
3. There may be a hardware failure of the CPU.
z RIO option has failed: The RIO option board (140CRP93x00) has been
determined to be unhealthy. Replace the board.
z Illegal node type found: This error is usually seen when downloading a program
to the CPU. Some of the things a user should look for include:
1. The user is loading/relocating logic from a CPU that supported a loadable
function block to another CPU that hasn't been configured for the same function
block. (ie HSBY or XMIT)
2. A constant or reference is outside the range of that particular CPU's instruction
set. This may occur when relocating logic from a 24 bit CPU to a 16 bit CPU. This
error is generally not seen as a hardware failure and the user is advised to
examine his user logic for incompatibility with the target PLC. RIO Option Has
Failed.
z User logic checksum error: The calculated user logic checksum does not agree
with the stored checksum. It can be caused by an illegal change in memory. The
user should try to reload his user logic program. If the error persists, replace the
CPU.
z Discrete disable table error: This error occurs when the user attempts to run
the CPU in Optimize mode with disabled coils in user logic.
z Bad configuration: The most probable cause would be that the memory has
been modified through the MODBUS/MODBUS PLUS ports. If this error occurs
during a program download, check configuration data for values greater than the
CPU's specified addressable range. This error can also appear if the CPU's
memory is defective.
