The specialty modules represent 2x3 bytes input and output data and seize 2
Instances in Class (0x67) and 2 Instances in Class (0x68).
Serial Interface Modules with alternative Data Format
750-650, (and the variations /000-002, -004, -006, -009, -010, -011, -012,
750-651, (and the variations /000-002, -003)
750-653, (and the variations /000-002, -007)
Note:
With the freely parametrizable variations /003 000 of the serial interface
modules, the desired operation mode can be set. Dependent on it, the
process image of these modules is then the same, as from the appropriate
variation.
The above Serial Interface Modules with alternative data format have a total of
4 bytes of user data in both the Input and Output Process Image (3 bytes of se-
rial data and 1 byte of control/status). The following table illustrates the Input
and Output Process Image, which have a total of 4 bytes mapped into each im-
age.
The specialty modules represent 2x2 bytes input and output data and seize 2
Instances in Class (0x67) and 2 Instances in Class (0x68).
