Abstract
PURPOSE: To eliminate the operation time difference of the timer element and thus to ensure a smooth synchronous adjustment by receiving the timer correction pulse from the external unit.
CONSTITUTION: Two process controllers SQC1 and SQC2 perform an operation with supply of process control signals I1 and IN, and then deliver process control signals O11WO1N and O21WO2N. These control output signals received the previous synchronous adjustment via the synchronous correction pulse signal given from outside and then control the process unit in the form of series. In this case, timers T1A and T2A necessary for the process control are set up via the count number of the short-time pulse TB which does not affect SQC1 and SQC2, and at the same time pulse TB of SQC1 and SQC2 is reset with every time τC during which the pulses of more than one is not produced in order to give correction to the synchronism. As a result, error TA can be reduced within time TB, thus constituting a timer which does not affect the process control.
