B-43

Sets the control-coprocessor date and time to the same date and time found

in the PLC-5 programmable controller.

Syntax

#include <copro.h>

unsigned DTL_CLOCK ()

Description

DTL_CLOCK synchronizes the control coprocessor time to within one

second of the clock for the PLC-5 programmable controller. This is a

one-time-only synchronization. The user can maintain synchronization by

executing DTL_CLOCK at regular intervals.

Since this routine performs I/O to the PLC-5 programmable controller, the

calling process must call DTL_INIT prior to calling DTL_CLOCK.
