The Processor Module PM511 is provided with a calendar clock which is backed up by the same
battery used for memory backup. You can set the date and time from the programming unit or
from a local operator station, for example MasterView 320. A slow, smaller adjustment in the
interval ±100 s can also be performed with the programming unit.
With Advant Controller 450 connected to MasterNet, as a part in a distributed control system,
the synchronization occurs automatically with other stations via a network with an accuracy
better than 3 ms.
If extreme synchronization accuracy is required between controllers (in the order of 2 ms) and
synchronization to an external clock, an external minute pulse signal can be connected to all
systems concerned.
The supervision module TC520 has a special input for external synchronization of the calendar
clock.

You configure the system in accordance with the hardware and software selected, for example,
the number of I/O boards, communication lines, functional units and PC programs. This is
performed using commands from a configuration tool such as the Advant Station 100 Series
Engineering Station and results in the internal organization and activation of the data base and
program areas.
Configuration/application building is introduced in Section 1.7.8.2, Principles of Application
Building.

The execution units in a PC program are normally given cycle times of 10 ms - 2 s (5 ms - 32 s
after reconfiguration). The internal program system (operating system and PC interpreter)
organizes the execution of the units with the periodicity selected, simultaneously performing
other tasks such as communication with a MasterView 320 and programming units.
Ordinarily, you can select the same cycle times for reading in values from digital and
analog boards.
