Presetting the forced-control position function as supplementary function (only in ETS 3.0d and
onwards)
As can be seen from the functional diagram (cf. Fig. 20), the forced-control position function can also be
combined with other output functions. In case of an active forced-control position function, the upstream
functions are overridden so that the output concerned will be locked in the forced position.

Fig. 20: Functional diagram of the forced-control position function
Set the parameter "Selection of supplementary function" on parameter page "Ax – supplementary
functions" to "Forced-control position".
The forced-control position function is enabled. The "Forced-control position" communication object and
the parameters of the forced-control position function are visible.
In case of the 2-bit forced-control position, the switching state of the output is directly determined by the
forced-control position telegram. The first bit (bit 0) of the "Forced-control position" object specifies the
switching state to be forced on the output. The second bit (bit 1) activates or deactivates the forced control
(cf. table 1).

Table 1: Bit coding of forced-control position
Updates of the forced-control position object from "Forced-control position ON" to "Forced-control
position ON" will cause the relay every time to switch the contact into the forced-control position. Updates
from "Forced-control position OFF" to "Forced-control position OFF" remain without effect.
An output under forced control from the bus can still be operated by hand!
