PROFINET IO Controller - General
Object: PROFINET IO controller
The PROFINET IO controller, like the slaves, is identified by the station name. For CIFX variants, you can also configure the IP settings here. Otherwise the settings apply from the superordinate Ethernet node.
|
Station name |
The station name of the device. It is used for unique identification of the device in the network. |
|
IP parameters |
|
|
IP address |
Note: Available for CIFX PROFINET only. If you insert the controller below an Ethernet adapter, you must define the IP parameters in the dialog of the Ethernet adapter. |
|
Subnet mask |
|
|
Default gateway |
|
|
Default slave IP parameters |
|
|
First IP address |
Range of IP addresses that CODESYS uses by default when inserting PROFINET IO devices into the device tree. If you use the Auto IP function in the scan dialog, then IP addresses are also used from this range. Then the next free IP address is selected. |
|
Last IP address |
|
|
Subnet mask |
|
|
Default gateway |
|
|
IO provider / consumer status |
|
|
Application stop --> Substitute values |
When the user stops the application, the provider state is set to "BAD". Then the slaves set the inputs and outputs to predefined substitute values. For further information, refer to "CODESYS default values - PROFINET IO Substitute values" at the end of this help page. |
|
Add to I/O mapping |
|
|
Port data |
|
|
Peer station/port |
Neighboring device with port that is connected to this port. You can accept this setting in the PROFINET IO Controller Topology tab. |
|
Cable length |
Length of the network cable (in meters)
When a cable length is specified, it is checked when the controller is powered up. An incorrect cable length causes an error message. |
|
MAU type |
Type of network cable |
|
Watchdog |
Note: Available for CIFX PROFINET only. |
|
Activate |
The presets for the watchdog are from the device description. |
CODESYS default values - PROFINET IO substitute values
PROFINET IO devices set their inputs and outputs to predefined substitute values when there is an interruption. These values are defined in the field device in contrast with default values. These values are usually zero, but specific substitute values can also be configured depending on the device.
The substitute values are set when
The connection is interrupted.
The controller sets the provider state for the incoming data to "BAD".
Other interruptions occur (exception in host application, incorrect parameterization, etc.)
If the option Application stop --> Substitute values is set, then the controller sets the provider states to "BAD" at application stop. The slaves set their substitute values. All incoming data from the controller (also default values) are ignored.
If the default values defined in the application should be set for an application stop, then you have to deactivate this option. In addition, you should set the option Refresh I/Os in stop (in the PLC settings). Otherwise, the CODESYS PROFINET IO controller is stopped.
: The incoming status information is added to the I/O mapping for all modules; provider state for the input data and consumer state for the output data.
