Determining the measurement values for inputs in "Digital" mode

The module chain described in the following is started every second and executed once, in order to be able to react as quickly as possible to level changes on inputs operated in "Digital" mode. Two measurement values are determined for these inputs. The "contact position" indicates whether current is flowing via the input. The "Actuation state" shows whether the contact is in idle state or has been actuated. The conditions under which a "Smart Action" (see Smart Actions) is triggered are also checked at one-second intervals, but are only available for the "Actuation state". If a level change is detected, an immediate recording is made. The currently valid values of all other inputs (including those operated in "Counter" mode) are also recorded. Regardless of this, all values are also recorded cyclically. The interval for this can be selected via the parameter "Record interval" (see Device settings).

The following table shows which value is recorded depending on the signal at the input. For the "Actuation state", it should be noted that the definition of the idle state depends on the type of contact connected to the input. With a "normally closed contact", the contact is closed in the idle state (i.e. current flows). With a "normally open contact", on the other hand, the contact is open in the idle state (i.e. no current flows). The type of contact can be selected via the "Contact type" parameter (see Input in "Digital" mode).

1	Conversion from "Contact position" to "Actuation state" (see Scale module)	3	Executes a recording when a level change is detected or the interval expires (see Record module)
2	Monitoring the conditions under which a "Smart Action" is triggered (see Smart Action module)	4	This module chain is started every second and run through once.
