Title:
DATA PROCESSING SYSTEM FOR REMOTE MONITOR CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP3294305
Kind Code:
B2
Abstract:
PURPOSE: To allow the system to easily cope with various processing by setting an expanded table area to a dual port memory and sending receiving data between both CPUs.
CONSTITUTION: When a monitor request of the state of all terminal equipments is implemented from an application CPU section to a transmission CPU, at first the application CPU writes a control command for monitor request of all terminal equipments to an area 1(3) of a block A(B) of a dual port memory 30. On the other hand, the written control command is read by the transmission CPU, which analyzes the command and data of the state of all the terminal equipments are written to an expanded table area C of the dual port memory 30 and return data representing the processing result with respect to the control command are written to an area 2(4) of the block A(B) to which the control command is written. Then, the application CPU reading the reply data reads the data in the expanded table area C and process the data.
