Title:
SLAVE STATION TERMINAL
Document Type and Number:
WIPO Patent Application WO/2014/061148
Kind Code:
A1
Abstract:
Provided are a slave station maintenance inspection protocol and a slave station terminal which is used in this protocol, whereby it is possible to easily carry out maintenance inspection work of the slave stations at sites where the slave stations are installed, in a control/monitor signal transmission system wherein a master station which is connected to a control unit is connected with a common data signal line to a plurality of slave stations which correspond to a plurality of output units, input units, or devices to be controlled, and data transmission is carried out with a data transmission synchronization protocol. A slave station upon receiving an instruction of a maintenance inspection from another terminal apparatus superposes the data indicating the mode corresponding to the content of the maintenance inspection instruction upon an administration data region disposed in a transmission signal and transmits the result to a master station. In addition, depending on the content of the maintenance inspection instruction, the slave station carries out an output data process in which the slave station control data is invalidated and output information is outputted on the basis of data which is received from the terminal apparatus, and/or an input data process in which slave station input data based on input information is invalidated and monitoring data is outputted to the common data signal line on the basis of the data which is received from the terminal apparatus.
