PURPOSE:To control a preceding accessed terminal device with the terminal control signal of a non-access mode, by setting freely the terminal control signal of an access mode and the terminal control signal of the non-access mode as the terminal control signal. CONSTITUTION:The first bit in a data transmission section TD of terminal control signals Sx and Sy transmitted from a main operation panel is defined as a mode setting bit M, and the presence or the absence of the transmission section of address data is indicated with the mode setting bit M. When the mode setting bit M is set to ''0'', a transmission section TA of address data is absent, and a transmission section TC or TB of control data or supervisory data is set throughout the data transmission section TD, and the terminal control signal SY of the non-access mode is tansmitted from the main control panel. When the terminal control signal SY of the non-access mode is transmitted from the main control panel, a terminal which is accessed by the terminal control signal SX of the access mode transmitted just before is controlled by this terminal control signal SY of the non-access mode. |
