Data Mapping
– Adding Diagnostic Information
Data Mapping offers 5 different types of information in addition to any scan lines specified for each
protocol.
1) Temporary Ram (Int64)
a) This offers five levels of 64bit Integer space to assist in multiple stages of math operations. For
example, you may wish to scale and then add 5. You can set up a single translation to scale with
the destination as the temporary ram. Then another translation to add 5 with the source as the
temporary ram.
b) The gateway will automatically convert the Source to fit the Destination, so there is no need for
Int 8, 16, 32 since the 64 may be used for any case.
In this example, Ram0 is scaled into Ram1. Ram1 is then increased by 5 and stored into Ram2.
Ram0 and Ram2 could be considered a source or destination group.
2) Temporary Ram (Double)
a) This is like the Temporary Ram (Int 64), except manipulations will be conducted against the
64bit floating point to allow for large data.
3) Ticks Per Second
a) The gateway operates at 200 ticks per second. This equates to one tick every 5ms. Thus,
mapping this to a destination will give easy confirmation of data flow without involving one of
the two protocols. If data stops on the destination end, then the RTA is offline.
IMPORTANT NOTE: Only add Diagnostic Information AFTER both sides of the gateway have been
configured. If changes to either protocol are made after diagnostic information has been added to the
mapping table, it is necessary to verify all mappings. Remapping may be necessary.
