Handling with VIPA data handling blocks Manual BG41/BG42/BG43
4-36 Rev. 99/49
QTYP
The source type is to be given in its own PLC.
Possible source types are:
DB for data blocks
DX for data block development
EB for the process image of inputs
AB for the process image of outputs
MB for flag bytes
Z for counter words
T for timer words
Other details result in a parametrizing error message PAFE: 27.
QDBN
If the source type DB or DX are selected, the DB no. is to be given into the right
byte. Valid area: 2...255. If this area is violated a PAFE: 28 is registered.
If the given DB or DX do not exist, the data handling block registers a
PAFE: 29.
QBWN
Byte/word number. By means of these operands it is determined, from which, e.g.
data word of the given DB, or from which byte, e.g. AB, the data is to be sent.
BWAN
Gives the amount of data in bytes/words, which are to be sent. At least 1
byte/word must always be sent, otherwise the data handling block registers a
PAFE: 31
