I/O Data Types
Predefined tags in the Logix Designer application for input and output data types
have a structure corresponding to the switch (module) selected when it was
added to the I/O tree. Its members are named in accordance with the port names.
For example, if you select the 18-port switch, the 18 port names corresponding to
that module are visible. The other member names (19…26) are hidden.
You can disable a switch port by setting the corresponding bit in the output tag.
The output bits are applied every time the switch receives the output data from
the controller when the controller is in Run mode. When the controller is in
Program mode, the output bits are not applied.
The port is enabled if the corresponding output bit is 0. If you enable or disable a
port by using the Device Manager Web interface or the CLI, the port setting can
be overridden by the output bits the next time they are applied. The output bits
always take precedence, regardless of whether the Device Manager Web interface
or CLI was used to enable or disable the port.
The following tables show input and output data types for all 26 ports of the
switch, as well as port assignments for data types.
Table 28 - Input Data Types
Tag Name Type Description
I:Fault DINT If there is s communication fault between the controller and the switch,
all 32 bits in the module fault word are set to 1.
I:AnyPortConnected BOOL Indicates that at least one port has an active link.
I:PortGi1_1Connected BOOL Indicates that a particular port has an active link.
0 = Link not active
1 = Link active
