Appendix A.2. Direct Addressing
Direct addressing allows data to be read from the McQuay device when the field name is unknown. McQuay
specifies the addresses in hexadecimal notation but they must be specified in the CSV file in decimal format. For
example, to read McQuay address 0x0400, the address in the CSV file must be entered as 1024.
If reading multiple addressing at once (i.e. if the length is greater than 1) it may be necessary to adjust the timeout
for the Map Descriptor.
It is possible to read multiple addresses using one Map Descriptorbut it is only possible to write to a single address.
Refer to examples on the following pages.
