Representation of process output data
The process output data of the BL20-E-1SWIRE modules is repre-
sented by objects 6200hex, 6220hex, 6221hex, and 6222hex,
6300hex or 6320hex for digital output channels of a BL20 station.
The user can choose between 4 different formats for representing
the values:
 Only one bit represented by each SUB-index (objects 6220hex,
6221hex and 6222hex), page 4-124
 8 bits represented by each SUB-index (object 6200hex), page
4-123.
 16 bits represented by each SUB-index (object 6300hex), page
4-125.
 32 bits represented by each SUB-index (object 6320hex), page
4-126.
PDO mapping of object 6200hex is always executed by default and
automatically for the first 8 subindexes.
This corresponds to the 64 bits of the SWIRE command interface. If
more than 64 process output data items are present, the PDO
mapping must be carried out by the user. A total of 36 groups of 8
bits each can be displayed (288 bits).
If the representation of the data bits is not required with the object
6200hex or if a different arrangement of the mapped objects is
required, PDO mapping must be carried out by the user.
