As an example, 16-bit, 32-bit and Short Floating Point Analog Output Object
Files are configured as below. Data File N17 has 10 elements, L18 has 10
elements and F19 has 10 elements accordingly. A total of 30 Analog Output
Object index are configured. Index 0 of the Analog Output Object is N17:0,
Index 10 is L18:0, Index 20 is F19:0 and Index 29 is F19:9.
Analog Output Command – Control analog output block (AOB)
When the controller is in Non-executing mode, the controller will not accept
an Analog Output Command. The controller returns a Control Status Code 7 in
the response. To access the objects 41(AOB), the controller mode should be in
Executing mode.
Note that Executing mode includes Run, Remote Run, Test Continuous Scan,
and Test Single Scan modes. Any other modes are Non-executing modes.
