Operating Settings for General Purpose Logic Timers
Operating settings are made using BESTCOMS.
Figure 4-52 illustrates the BESTCOMS screen used to
select operational settings for the Logic Timers element. To open the Logic Timers screen, select Logic
Timers from the S
creens pull-down menu. Alternately, settings may be made using the S<g>-62/162
ASCII command or through the HMI interface using Screens 5.x.9.1 and 5.x.9.2.
Figure 4-52. Logic Functions Screen
At the top center of the screen is a pull-down menu labeled Logic. This menu allows viewing of the
BESTlogic settings for each preprogrammed logic scheme. User or custom logic must be selected on this
menu in order to allow changes to be made to the mode and inputs of the element.
To the right of the Logic pull-down menu is a pull-down menu labeled Settings. The Settings menu is
used to select the setting group that the element’s settings apply to. See Section 7, BESTlogic
Programmable Logic, Logic Schemes.
Using the pull-down menus and buttons, make the application appropriate settings to the Logic Timers
element.
Table 4-33 summarizes the operating settings for General Purpose Logic Timers.

∗ Time delays less than 10 cycles can be entered to the nearest 0.1 cycles through the HMI. All time
delays can be entered to the nearest 0.01 cycles from the ASCII command interface. Time delays entered
in cycles are converted to milliseconds or seconds. Increment precision after conversion is limited to that
appropriate for each of those units of measure.
