FEHL
All bits of these bytes are set to 0, if functioning correctly. In the case of a
malfunction, an error code is entered. The error is acknowledged automatically,
i.e. the byte is reset to 0 once the cause of the error has been eliminated.
An overview of the possible error codes are to be found in chapter 4.1.5.3.
NEUS
As long as the bit is at signal state 1, the handling of the function block will be
discontinued.
Example FB3 (SEND)
31 bytes should be transmitted through channel 1, which are filed from data word DW5 in DB 23.
The DIL switches are set to the absolute address F1A0h and the M4.7 is used as the enable bit. Any
error codes, which may possibly arise, should be filed in MB200.
