MONITOR INFORMATION COLLECTION SYSTEM

PROBLEM TO BE SOLVED: To correctly monitor the state of a system independently of the inserting/ejecting timing of a package by providing the system with a monitor information collecting part for collecting the prescribed monitor information of unspecified units and returning the collected information to a monitoring part at the time of collecting monitor information from a specified unit. SOLUTION: In the case of collecting monitor information from a specified unit (c), the prescribed monitor information of unspecified units (a), (b), (d), (e) having prescribed relation with the specified unit (c) is returned to the monitoring part in accordance with table information obtained from a table means for regulating relation of the specified unit (c) with the unspecified units (a), (b), (d), (e). Since the monitoring part can simultaneously refers to the prescribed monitor information of the units (a), (b), (d), (e) even when an error is included in the monitor information from the unit (c), a real error state can be synthetically judged. Thereby the system state can be correctly monitored independently of the inserting/ejecting timing of a package.
