RSLinx – Training Guide 19
Application Notes and Suggestions (continued)
• When receiving unsolicited messages from an SLC 500 processor via a 1785-
KA5 Bridge, the DDE topic's remote configuration must be set to Internet mode.
Ø Also, in the SLC 500 message instruction, the remote bridge node
address must be set to 0.
Ø Also, unsolicited messages sent from a PLC or other node to RSLinx will
cause errors if no DDE clients or C-API applications are running to
receive them.
• When downloading a program to an SLC 500, stop all data connections active to
that station. Under certain instances, the processor may fault if applications
continue to poll the SLC during a download.
• If you are running Windows 95 using the 1747-PIC driver with WINtelligent LINX,
but are no longer using WINtelligent LINX, we recommend you change the
following entry in your system.ini file (located in \Windows directory). Under the
[boot] section of the system.ini file, change comm.drv = icomcomm.drv to
comm.drv = comm.drv After changing this entry, restart Windows 95.
• RSLinx does not automatically create a NetDDE share entry in the NT or
Windows 95 registry for configured topics. For help on enabling NetDDE and
creating NetDDE shares, refer to the NetDDE help page.
• RSLinx will not reread a User Defined Structure list for SoftLogix until the topic is
stopped and restarted.
• RSLinx supports no-interrupt configurations when using Allen-Bradley network
cards; however, we recommend assigning an interrupt to increase driver
performance.
• If you have Auto Hide on for the Windows task bar, every time you go to the task
bar (if animation is on), it reduces your packets/sec speed due to computation
times.
• Do not use the power saver option on your computer when running RSLinx. Use
either the BIOS or Control Panel to disable this option.
