Profibus DP Configuration Example for MELSEC System Q
2 - 20
MITSUBISHI ELECTRIC
For the process images of the individual STlite modules please refer to the appendix, section A.1. For
example, reading a value of 16384 (4000
H ) from D1001 means that a voltage of 5.00 V is applied to
channel 1 of the STL-AD2-V or, if you want to output 10 V on channel 1 of the STL-DA4-V1, write 32760
(7FF8
H ) to D2001.
Rearrangement of the Modules
Another option for this example to allocate 16 bit input and output data to a single data register is to
mount first the analog modules and afterwards the digital modules.
The device monitor for this configuration is shown on the next page.
