ControlĆCoprocessor Memory Functions

Use DTL_SIZE and DTL_TYPE functions to determine the size and

location of control-coprocessor memory required to store the contents of

the data item in the control-coprocessor format. See Table 5.F.

Utility Function

Use the DTL_CLOCK function to synchronize the control-coprocessor

date and time with that of the PLC-5 programmable controller. The

control-coprocessor time is synchronized within 1 second of the PLC-5

programmable-controller clock. This is a one-time-only synchronization.

The application can maintain synchronization by calling DTL_CLOCK at

regular intervals.
