Upper Layer Status Read Definition
The node status is divided into two types: FA link protocol upper layer status
(referred to as the upper layer status) and FA link protocol status (referred to as
the FA link status).
Upper layer status
The upper layer status is divided into upper layer operation information and
upper layer error information.
Upper layer operation information
ƒ RUN: Indicates that the upper layer program is running.
ƒ STOP: Indicates that the upper layer program is at a stop.
Upper layer error information
ƒ NORMAL: Indicates that the upper layer is normal and both cyclic data and
message data are guaranteed.
ƒ WARNING: Indicates that there occurs an error that permits continuing
operation in the upper layer but both cyclic data and message data are
guaranteed.
ƒ ALARM: Indicates that there occurs an error that does not permit continuing
operation in the upper layer and both cyclic data and message data are not
guaranteed.
Contents of error in the upper layer: Indicates the contents of an error in the
upper layer program.
The upper layer program means those that have an interface with the FA link
protocol upper layer, which for the MVI-FLN module is he CompactLogix
processor.
