Controlling the Digital Outputs
Since no function is assigned to the digital outputs in

period duration mea-
surement
²
mode, they can be used as desired.
The DO byte is used to specify the state of the digital outputs.
0: Switch off output
1: Switch on output
The module firmware switches off the outputs during the transition of the
CPU to the STOP state (BASF/OD signal)
.
Write the DO byte to address

module start address
+ 0.

Table 6-7 shows the assignment of the bits of the DO byte to the measuring
channels.
Note
Control of the digital outputs must be programmed with a word access.
