McQuayProxyExt properties

All McQuayProxyExt types (McQuayAnalogProxyExt, McQuayBinaryProxyExt, McQuayEnumProxyExt) share the same set of configuration properties. Any one of the McQuayProxyExt types is a proxy for one piece of data of interest in a McQuay controller. This single piece of data is specified by its combination of register address and number of address registers (register length).

Figure 11 shows the property sheet of an example McQuayProxyExt.

In addition to typical ProxyExt properties, the proxy extension in any McQuay proxy point includes these specific properties:

Register Hex

Four digit hexadecimal address for the register (or starting register) where the data item resides.
Data Len Registers

Number of registers used for the data item, typically either 1 (the default) or 2.

Refer to the appropriate McQuay documentation for the target McQuay controller, and enter this needed register address information for each proxy point.

The single exception to this is for a McQuay Enum point, where you do not enter register address information, but instead select from the several available “Enum Types”.
