0
The output bytes of channel 1 (D0, D1) are used for the register values.
2.1.2.9.3

Example 750-511

The following examples illustrate the register read and write modes. The
values are binary. In order to make things easier, only the process data of
channel 1 is mentioned.
Read register 2
The module is in process date exchange:
Control byte C0
Register read access is available when bit 7 is set and the register address is
entered in the control byte.
Control byte C0
You can reactivate the process data exchange if you erase bit 7.
Control byte C0
