The controller will then flag an “Open Circuit” fault. If the flag stays active for the 2312h
AO Error
Reaction Delay
time, then an appropriate EMCY message will be added to object 1003h
Pre-
Defined Error Field
. The application will react to the EMCY message as defined by object 1029h
Error Behaviour
at the sub-index corresponding to an Input Fault. Refer to section 2.2.4 and
2.2.13 for more information about objects 1003h and 1029h, including the complete list of EMCY
messages.
Once the absolute difference between the target and feedback FV comes back with the tolerance
defined in 2311h, the error flag is cleared. This means that when the output is commanded off, the
flags are automatically reset, since the target and feedback are now both zero.

Internal Function Block Control Source
The 2In 2Out Signal controller allows for internal function block sources to be selected from the list
of the logical function blocks supported by the controller. As a result, any output from one function
block can be selected as the control source for another. Keep in mind that not all options make
sense in all cases, but the complete list of control sources is shown in Table 22.

– Control Source Options
In addition to a source, each control also has a number which corresponds to the sub-index of the
function block in question. Table 23 outlines the ranges supported for the number objects,
depending on the source that had been selected.
