Summary:
I am using the GETCP driver to communicate with a GE Rx3i PLC and I've noticed an error in the syslog.dat and kernel similar to the one below:

 2010/08/02-08:37:30.514 Error: General error
  READ     0008 PORT1_BOARD1        IODev                          R7401  128
  Generic 000008 Driver 00066960 (0x00010590)

What does this mean? 

Solution:
This error is indicating that the GETCP driver is trying to from read an address that does not exist in the PLC. It is possible that your PLC has been reset thus reverting back to its default address ranges and that the address that is being requested is outside the default range i.e. 1-1024 for System Registers (R), 1-64 for Analog Inputs (AI) and Analog Outputs (AQ)
Keywords:
GETCP, Rx3i
