Requests to the DN611B
When controlling the DN611B with a controller or inputting/outputting data, using a "user function block" that
combines the MREAD and MWRITE instructions simplifies the program.
This section describes the "user function block" of various requests issued from the controller to the DN611B.
There are six types of requests from the controller to the DN611B.
The six types of requests are divided into executable/ unexecutable requests according to the DN611B
operation mode. The DN611B operation mode is explained in "4.3.1 DN611B operation mode". The
relationship between the various requests and the operation mode is shown in Table 4-2, and the details of
the six types of requests are described in "4.3.2 Reset request" and later.
For details on how to create and register user function blocks, refer to the "Engineering Tool 4 User's Manual
Basic" (6F8C1290) or the Engineering Tool Online Manual.
