** After parameters have been changed, it is necessary to perform an update to activate. If an update is not
performed when the parameters have been changed the parameters will be updated during the next update
cycle.
Access Type
NOTE: How the Fieldbus board accesses the respective Control board variable.
Std — Standard Parameters. These values are constantly updated from the Control Board, except
during the ‘Signature’ capture.
Info — Device Information Parameters. These values are read only at start-up or when any of them
are changed. The number -n is used to group parameters into manageable sizes.
Diag — Advanced Diagnostic Parameters. These values are active only when the parameter ‘Enable
diagnostic Variable Access’ is set in TEST_MODE.
