Abstract

PURPOSE: To avoid the delivery delay of emergency data, by deliverying the numbering information of the data to be collected from the master to the slave station, and by deliverying of the slave station to the master station through the collection of corresponded data with priority.
CONSTITUTION: The binary data of plant and the numeric data 10 are collected with the process input unit 6 of the slave station 5, and thet are stored in the conditional change waiting table and the numerical data storage table in the calculator 7. In this case, the data of the conditional waiting table is stored in the order of the level of data, and the numeric storing table stores data in the order of the data number fixed. When the collection of emergency data is needed for the master station, the polling data gnerated to the slave station is added with the data class representing the linary data and the numerical data and with the emergency data request format consisting of the emergency data number and is delivered to the slave station. When the delivery request of the emergency data is detected by the step 1. the emergenct data is edited according to the emergency data number with priority in th step 2, and at the step 3, the normal data is edited and the edited data is transmitted to the master station in the step 4
