Abstract

PURPOSE: To ensure reception of only important interruption request for the whole system and thus to eliminate the useless process time, by providing the interruption request level code to the transmission frame and then designating the interruption reception level through the computer.
CONSTITUTION: Interruption request level code 6 of transmission frame 50 sets the level to the interruption request contents as the whole system. Code 6 is provided by 2 bits via the encoded level and then divided into 4-level interruption request. Master station ST2a sets the indicated interruption reception level to code 6, and other interruption request slots are set to 0 and circulated. Each slave station ST compares the level of circulated code 6 with its own interruption request level when the interruption request is given from various units. In case the own level is higher than the level of code 6, the contents of code 6 are rewritten to the own level. At the same time, other information are also recorded. In this way, the interruption request of the highest level is accepted in preference
