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.
