Addressing Of The Cfw-09 Variables In The Fieldbus Devices - WEG CFW-09 User Manual

8.12.7.4 Addressing of the
CFW-09 Variables
in the Fieldbus
Devices
CHAPTER 8 - CFW-09 OPTIONS AND ACCESSORIES
E26 - The desired content value is out of permitted range.
E27 - Caused by:
a) The function selected in the Logical Control is not enabled for the
Fieldbus, or
b) The control of the Digital Output is not enabled for the Fieldbus, or
c) The parameter write is read-only.
The fault indication described above will be removed from the Logical
Status when the desired action is sent correctly. Except for E27 (case (b)),
which reset is via write in the Logical Control.
Example: supposing that no digital output is programmed for Fieldbus, thus
when in position 3, the word 11h is written, the inverter answer indicating
E27 in E.L.. To remove this indication from E.L., you must:
1) Write zero in Pos. 3.(since no DO is programmed for Fieldbus);
2) Change the variable of the logical control, to remove from E.L. the E27
indication.
The removal of the fault indication from E.L. described above, can also be
realized by writing the code 999 in Pos. 5 of the "Variables written in the
Inverter". Except for the fault E27(in the cases (a) and (b)), which reset is
realized only through the writing in the Logical Control, as above exemplified.
NOTE!
The faults E24, E25, E26 and E27 do not cause any change in the inverter
operation status.
HMI displays:
E29 - Fieldbus is inactive.
- This display appears when the physical connection of the inverter to the
Master is interrupted.
- You can program in Parameter P313 the action that the inverter shall
execute when the fault E29 is detected.
- When the PROG key of the HMI is pressed, the E29 Fault indication is
removed from the display.
E30 - Fieldbus Board is inactive.
This fault is displayed when:
1) P309 is programmed different than Inactive, without Fieldbus board in
the XC140 connector of the CC9 control board; or
2) The Fieldbus board is inserted, but is defective; or
3) The Fieldbus board is inserted, but the standard programmed at P309 is
not equal to the standard of the used board.
You can program in Parameter P313 which action the inverter will
perform when E30 is detected.
When the PROG key of the HMI is pressed, the E30 Fault indication is
removed from the display.
The variables are arranged in the memory of the Fieldbus device, starting at
the address 00h, both for writing and reading. The address differences are
corrected by the protocol and by communication board.
The way the variables are arranged at each address in the memory of the
Fieldbus depends on the equipment that is used as Master. For instance: in
the PLC A the variables are arranged as High and Low, and in the PLC B the
variables are arranged as Low and High.
