–
–
in the -HI- value parameter for the signal -HI- set the value of 0x0000,
◦
Blocks configuration mode parameter set as automatic ,
•
Max.block size parameter set as 5, because the slave device selected in this

Task:
The task is to configure the Slave device (e.g. a 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 the ACM module, in which the MB2 port is used.
Solution:
First we need to configure the device according to the following recommendations, then
connect the device in according with Fig. 7.155 .
Register type parameter set as HOLDING ,
in Register number parameter write 2h,
Data format parameter set as 16 bits, unsigned ,
in Data shift parameter write 0,
in Data mask parameter write 0x00C0 ,
