3.3 Timing
Figure 4: Timing diagram
1: The selected function (in this case “TriggerOn”) is executed if the “Req” input is triggered
by a rising edge. The “TriggerOn” bit must be selected at the same time/in advance. Only
one function can be executed at the same time, otherwise an error will terminate the se-
quence.
2: The “ReqDone” flag indicates that the sequence has been successfully completed. If an
error occurred, the sequence is terminated with “Error”. The parameter “Errorcode” contains
the error code.
3.4 Behavior in the case of an error
If the function module has an incorrect input value or faulty input circuit, an error bit (Error) is
set and an error code (Errorcode) is output. In this case, no further processing is carried out.
The parameters (Error, Errorcode) of the function module retain their value until a new com-
mand is started.
