Error description
* 1 In a single CPU configuration, reset the C Controller module.
In a multiple CPU configuration, reset CPU No.1.
Corrective action
Check the parameter.
Check the specified module.
Reboot the operating system.
Use the path pointer returned by "QBF_Open"
function.
Check the I/O No.
Check the I/O access size (I/O No. and read/
write size).
Check the I/O No.
Check the program execution type.
Check the offset.
Check the I/O No.
Check the specified buffer memory size.
Check the offset plus size.
Check the data storage buffer pointer.
Check the read size and read area size.
Check the specified time.
Check the I/O No.
Check if the intelligent function module is
mounted properly.
Check if the driver has been started.
