As long as Read, Write, and Parse continue to increment and Err does not
change, this indicates normal backplane activity. An occasional backplane error
may occur, even in normally functioning systems. So, if the value in the Err
counter slowly increases over time, this is generally not a cause for concern.
However, if normal backplane transfers appear sluggish or non-functional, if input
data is being lost or output data is not being sent, especially when the Err
counter is incrementing frequently, this could indicate a hardware failure, I/O
configuration problem, or, for remote rack installations only, a process network
problem that may need to be corrected.
GSCCLOCKTYPE
This data type allows the clock value to be exchanged between the module and
processor.
GSCCONTROL
This data type creates the Boolean (single-bit binary) tags to hold control bits for
special functions.
