Example
Setting the bit addresses of the "Motor CW" and "Creep speed" commands to a logical one
and reading the process image input:
● Address field: The address of the 3RW5 soft starter is not entered in the example (-).
● The commands start in register address 0x8200. The bit addresses of the commands are:
– "Motor CW": 0x8200
– "Creep speed": 0x8206
● The remaining bits of the byte are controlled with a logical zero (0x41).
● The process image input starts at register address 0x8000 and occupies 8 registers.
● As feedback, the process image input is returned. In the example, the returned data are
not entered (-). Note that the requested commands are not returned as a new status in
the exact same cycle because implementation of the commands takes a while. The new
status is not returned in the process image input until several communication cycles later.
You will find the data tables for the process image output and process image input in
chapters Process image output (PIQ) (Page 81) and Process image input (PII) (Page 80).
