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
ETC2002 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 ETC2002 exchange
area for accessing the acquired data from the remote
applications.
4. Check the “Polling Enabled” box to activate the exchange.
