Technical Note Details:
Background:
RSView32 does not directly support Unsolicited Messages. Both WinLinx and
RSLinx support this feature when an Unsolicited DDE Topic for the device is
configured. RSLinx version 1.7.62 or higher has a data collection mode that
allows a DDE topic to be unsolicited with a scan rate. The maximum scan rate
can be set to 3600000 msec (equivalent to 1 hour) allowing the user to display
screens and immediately get the current value out of the PLC or SLC device and
receive unsolicited messages when sent.
