Task:
The task is to configure Slave device (eg Flowmeter) output channel. The Slave device
address is 5. we write data to register 1, 2, 4 and 8. For communication in this task we use
ACM module, in which the port MB2 is used.
Solution:
First we need to configure the device according to the following recommendations, then
connect the device according to
Fig. 7.130
.
