New Functions and Features 6-23
Option to hide Linx Gateways • Several customers have requested the ability to not show the
Linx Gateway driver in RSWho because it creates confusion.
With this release, a configuration option to disable this node
from appearing in RSWho is provided.
1784-PCC Auto-addressing • This driver now includes an option for auto-addressing. If
selected, the driver will automatically select an empty MAC ID
for communicating on the ControlNet network each time the
hardware is connected to a new network.
DDE/OPC performance
improvements
• Several infrastructure changes will improve system throughput
when requesting large amounts of data. Code has been added to
“backoff” on the polling rate when system is under heavy load
to prevent thrashing resulting in excessive CPU utilization.
New online help • Online help information has been converted to HTML Help
format to improve readability and usability.
New PIC driver for Win9x • Several reported timing problems have been addressed with a
new driver.
ControlLogix Bridging Support • You can now bridge from one ControlLogix system to another
over Ethernet. Configure network browse list by specifying the
IP addresses for 1756-Enet, PLC-5E or SLC-5E modules.
New SOFT5 keyword • A new PLC keyword, "SOFT5" has been added to the
DTL_C_DEFINE string. Specifying this keyword will cause the
DTL library to accept file numbers up to the limits of the Soft-5
controller.
Restrict RSLinx Gateway Access • You can now restrict remote access to an RSLinx Gateway server
by specifying allowed client connections. This feature is disabled
by default. If enabled, only clients identified in the list will be
granted access to the gateways drivers.
Restrict Remote Access • You can now restrict remote access to a RSLinx Gateway server.
This feature is disabled by default. It can be enabled and
configured using the new Client Access List property page,
which is available from the RSLinx main menu under
Communications > Configure Gateway.
VT_BOOL • Added support for VT_BOOL data type in DDE/OPC Toolkit for
OPC clients
