General Instructions for Start-Up
DOLFI Cannot Establish a Connection
a) A baud rate other than that in DOLFI was set in Parameter B001.
B001, Baud rate RS-232/485
Baud rates possible [baud]
09600
19200
It is recommended that Parameter B001 be set to 09600 baud for the
"Connect" process. The baud rate for the download can be set to a
different value in DOLFI.
If the programming of a module was terminated, (e.g., due to interference
at a serial interface), the baud rate for the download still remains set in
the DKC. For DOLFI to be able to re-establish a connection, it is
necessary to set the connect baud rate to the same value used for the
most recent download.
If the unit has been switched back on and the display reads dL, then a
baud rate of 9600 is always set.
b) The receiver and unit addresses are not identical to the addresses set
at the controller via switches S2 and S3.
c) Parity check in Parameter B001: Parity must be set to NO or EVEN.
DOLFI Cannot Open the *.ibf File
DOLFI signals "Wrong *.ibf format" when opening the *.ibf file.
The *.ibf file was generated using a different release and the *.ibf format
has changed from that used in the DOLFI version.
To open the file, the correct DOLFI version must be used. This version
can be obtained from the manufacturer.
DOLFI Signals Timeout
Timeout messages appear while the *.ibf file is being transmitted.
Interference at the serial connections could be the problem or a
deactivated COM interface FIFO buffer.
This function can be activated as follows:
Windows 95:
Settings → Control Panel → System → Device Manager
Start
Ports (COM and LPT) → COM port (COMx) → Port Settings →
Advanced
Activate FIFO buffer using standard setting
Windows NT:
Start → Settings → Control Panel → Ports → COMx → Settings →
Advanced
Activate FIFO buffer
