Abstract
PURPOSE: To reduce the effect given to the processing speed of the system, by providing the circuit inhibiting the delivery of strobe signal from CPU to the second unit for a given time greater than the callout time to the input and output module with the coupling section of the extension bus line of the first unit.
CONSTITUTION: The first unit 1 including CPU2, and input and output modules 3-11...3-13 is connected to the second unit 6 having only the input and output modules 3-21...3-23 with the extension bus line 5. The coupling section of the bus line 5 of the unit 1 is provided with the circuit inhibiting the delivery of the storobe signal to the modules 3-21...3-23 in the unit 6 from CPU 2 for a given time greater than the access time to the modules 3-11...3-13 of the unit 1. Thus, the presence of the extension bus line reduces the effect given to the processing speed of the system.
