4.4.6. Map Descriptor Example #3 - Verify.
The verification string contains revision and model information about the Gage. In this example a Map Descriptor is defined which
controls the task of reading verification data from the Setra Model 370 Digital Pressure Gage. The task gets performed every 5.0
seconds. When a response is received the data is stored in the Data Array called DA_VERIFY stating at element zero (the offset).
Each Gage verification reading requires the driver store a string containing two lines of data. The actual length is unknown in
advance and it is recommended that 100 Data Array elements be reserved to store the verification sting. The verification string is
stored by writing each consecutive letter in consecutive Data Array elements. It is recommended that the Data_Array_Format is set
to BYTE in this case. This will enable the use of the “String” display to read the verification string in RuiNet.

The name of a Node defined in
the CSV file. The node name
connect the MD to a node
which in turn points to a
connection Thus the driver
knows what port and port

Tells the driver
to schedule this
