A.4.5
Checking and activation of the parameter file
The EMCA checks automatically whether a transmitted parameter file is compatible. This takes place
both when the download is completed and the file is to be loaded as well as directly after transmission
of the header information. If the parameter file is not compatible, the EMCA responds with an error and
the corresponding error code.
Activating the transmitted parameter file
Through the download, the parameter file is stored in the memory of the EMCA (permanent memory),
and the previously stored file (permanent memory) is deleted after the new file has been successfully
checked. The currently active parameters remain uninfluenced by this.
The parameters of the new parameter file become
active only after
:
The EMCA is restarted
–
PNU 127.3 “Reset device” is set
–
The power supply is switched off/on
–
FCT plug-in menu [Component] [Online] [Restart controller] ( [Component] [Online] [Restart Con
troller] ).
Setting of PNU 127.4, “Load parameter values from parameter file”
But with this method, changed parameters of the error management are
not
taken over.
A.4.6
Sequence of parameter file transmission
Parameter file transmission takes place in the following sequence:
1. Start data transmission. The sequence number begins with 0.
2. Transmit user data packages and increment sequence number.
As a handshake, the response is made with the same package ID after receipt of the data package.
The data of the parameter file are transmitted beginning with sequence number 1. If the sequence
number has reached its highest value 31, counting begins again at 0.
The intermediate step through “no job” is eliminated in this EFPC variant, because the package ID
changes in every new telegram.
3. Data transmission completed or stop data transmission.
Parallel to the transmission, the controller must evaluate possible errors.
Before and after data transmission, the telegram “no job” is exchanged cyclically between the control
ler and EMCA.
A stop, sending of “No job” or an error message can be written at any time in the control bits and inter
rupts the upload or download. A check of the sequence number then does not take place.
