I/O Data Types

Pre-defined RSLogix 5000 tags 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 a user selects 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 will be 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 may be overridden by the output bits the next time they are applied.

The output bits will 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.

Input Tags

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 a link status or active

0 = Link not active

1 = Link active
