Entering DTAM Configuration Data

14–6

Only available on the DTAM Plus with the Clock/Calendar option, this

setting controls synchronization between a DTAM Plus and a PLC-5 or SLC

controller. The time is synchronized between the DTAM Plus and controller

approximately every 60 seconds.

The time synchronization does not update when the DTAM is in the P-A/D

mode (see Appendix C) or while a data entry screen is displayed.

When you select Time Synchronization from the DPS Configuration - Option

Selection menu, the following is displayed:

The DTAM Plus Time Synchronization consists of two selections:

Select: To:

Read Time Set the DTAM Plus clock by reading the time and date from the

controller.

Write Time Write the DTAM Plus time/date settings to the controller. You can

write time data to a controller even if the controller does not have a

clock source.

The PLC-5 always writes the time to addresses S:18 through S:23. When

you read time or write time with an SLC, you are shown the current time

base register and are prompted to enter a new register value:

The time base register is the initial register of the sequential registers storing

the time. For example, if the time is stored in SLC registers N7:1 to N7:8,

the base register would be N7:1.
