To configure a real-time data exchange:
1.
Define the device address for a data exchange. Note that the real-time,
status event and write data exchanges with the same exchange number
are internally linked in the ETC II to the same device address.
2.
Specify the start register address of the area in the device Modbus map
you wish to be polled via the exchange.
3.
Type the number of registers in the exchange. Up to 114 registers can
be specified for a single exchange. As you type the register address
range, PAS immediately shows you the start register address in the
ETC II exchange area for accessing the acquired data from the remote
applications.
4.
Check the “Polling Enabled” box to activate the exchange.
Status Event Exchanges
To enter the Setup dialog, select the ETC II site from the list box on the PAS
toolbar, select ETC II Setup from the Meter Setup menu, and then click on
the Status Event Exchanges tab.
