New Functions and Features 9-5
Updated Network API Support for Visual Basic
The Network API for Visual Basic has changed from previous releases.
Previously, to add Network API support to a Visual Basic project, a developer
would need to add references to 3 .bas files.
The mechanism has been modified, and Visual Basic applications that need to
use the latest Network API will no longer need to include references to the
.bas files. Instead they will need to include a reference to the Network API .dll
from the project references dialog.
To include a reference to the Network API .dll, do the following:
1. Select Project References from the menu.
2. Check the reference “Honeywell Network API Type Library and click
OK.
To Browse for information about the available functions, press F2 to
open the Object Browser.
3. Select HscNetapi from the dropdown combo box.
This change does not affect C/C++ applications using the Network
API.
Hardware Enhancements Ethernet Supervisory Network
In addition to the 1756-ENET/A, the 10 megabit 1756-ENET/B and the
10/100 megabit 1756-ENBT/A have been qualified for use as the Supervisory
Network between the 1757-PLX52 controllers and the R500.1 ProcessLogix
Server.
At the date of this publication, the ENBT/A is available and is the preferred
version of this module. The 1756-ENET/A is now obsolete and the
1756-ENET/B is in the process of being obsoleted, however both the
1756-ENET/A and 1756-ENET/B will continue to be supported but will not
be available for purchase.
