4.4.5 Map Descriptor Example 2 – Read On/Off Status (Data stored differently)
This example reads the same data as the previous example. The difference is that the data is stored differently. In this example the data is
unpacked and stored in 16 consecutive data array elements – one element per module position.
Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Function, node_name, Length, Scan_Interval, opto22_function , opto22_format
DEVICE77_STAT , DISC_INPUTS , 0 , rdbc , DEV77 , 16 , 5.0s , READ STATUS , Bit
The length has
changed to 16 to
reserve 16 data array
elements for this
map descriptor.
This is how the
driver is instructed
to unpack the digital
data.
