Error detecting system for external set value

Abstract

Abstract PURPOSE:To detect an error of an external set value, and to facilitate an increase of spatial switches by sending out external set value information which is set respectively at the time of an installing work of plural spatial switched which are increased, and detecting the error of this external set value information. CONSTITUTION:External set value sending-out means 101, 103 send out external set value information which is set, respectively, at the time of an installing work of plural spatial switches. External set value error detecting means 105, 107 extract each external set value information and detect the error of the external set value, respectively. From the external set value sending-out means 101, 103, the external set value information which is set, respectively at the time of the installing work of plural spatial switches is sent out, and by the external set value error detecting means 105, 107, an error detection of the external set value information which has been sent out is executed. In such a way, the external set value which has been set can be checked.
