2.6.5 Write codes (L_ParWrite)
This FB is used to write parameters, with Lenze so−called codes. The FB can write both the PLC
codes and codes of other devices via the system bus (CAN).

1 ... 65335 Time−out time in ms is the time for processing the order.
·
Initialized with 1000 ms.
·
This variable can be parameterized by means of a user
code.
bExecute Bool VAR_INPUT FALSE/TRUE transition activates a write request.
wIndex Word VAR_INPUT 0 ... 65535 Code index
Conversion formula: Index = 24575 − code number
bySubIndex Byte VAR_INPUT 0 ... 255 Subindex (subcode number) of the code
abyData Byte [0 ... 3] VAR_INPUT The four data bytes with the code value to be written.
byFraction Byte VAR_INPUT 0 ... 254 Number of decimal places of the code to be written.
255 Code without decimal places
(e.g. hexadecimal code).
byComChannel Byte VAR_INPUT 0
Constant:
Writing a PLC code.
C_PLC
10
Constant:
Writing a code in a device connected via the system bus (CAN).
C_SYSTEMBUS_CAN
wTargetAddress Word VAR_INPUT Selecting the parameter data channel of the target device
(only with byComChannel = 10)
1 ... 64 Data transfer via SDO1 of the target device:
wTargetAddress = CAN device address of the target device
65 ... 127 Data transfer via SDO2 of the target device:
wTargetAddress = CAN device address of the target device +

bDone Bool VAR_OUTPUT TRUE Order has been processed (observe bFail ).
bBusy Bool VAR_OUTPUT TRUE Order is being processed.
bFail Bool VAR_OUTPUT TRUE Error occurred.
