Number of Connections
The module supports a maximum of 131 connections. However, 3 of the 131 connections are always reserved for redundant control. Therefore, 128 connections are available for standard use. Because the connections are reserved, they will always appear in use even when no connections are open. To access the connection information, right-click the module in the RSWho window of RSLinx Classic software.
Corrected Anomalies with Revision 20.013
Cat. No. Description
1756-CN2/B,
1756-CN2R/B
Corrected: A communication fault occurred when the module was in an I/O chassis and configured as rack optimized. In RSLogix 5000 software,
the outputs in the chassis go to the states configured for Program mode instead of Fault mode.
The workaround previous to being corrected was to use a direct connection instead of a rack optimized connection for the I/O adapter.
Lgx00105037; Product Notice 2010-04-002
Corrected: The 1756-CN2x module returned an error to a `Hold Net
Resource’ request if the module received the request immediately after responding with success to a previous `Obtain Network Resource’
request.
This was not an issue for RSNetWorx software because it waits approximately 15 seconds after the `Obtain Network Resource’ request
before issuing a Hold request.
The workaround previous to being corrected was to program a short delay between the two requests. Lgx00103680 Corrected: Upon powerup, the OK status indicator of the 1756-CN2x modules may have been red. The module status display indicated one of these messages because the 1756-CN2x modules inaccurately detected
the size of the redundant chassis:
• CmdConnOpen.cpp Line 630
The 1756-CN2x/B communication module firmware revision 20.13 is not compatible with the 1756-CN2x/A communication module hardware. Number of Connections The modules support a maximum of 131 connections. However, 3 of the 131 connections are always reserved for redundant control. Therefore, 128 connections are available for standard use. Because the connections are reserved, they will always appear in use even when no connections are open.
