IO Controller – General

Objekt: PROFINET IO Controller

The PROFINET IO controller, like the slaves, is identified by the station name. For AC500 communication modules, 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.

Table 459: IP Parameters
“IP address”	Note: Available for AC500 communication module only. If you insert the controller below an Ethernet adapter, then you need to define the IP parameters in the dialog of the Ethernet adapter.
“Subnet mask”	The subnet mask used by the device.
“Default gateway”	The default gateway used by the device.

Table 460: Default Slave IP Parameter
“First IP address”	Range of IP addresses which CODESYS uses by default when inserting PROFINET 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. The next free IP address is selected here.
“Last IP address”
“Subnet mask”
“Default gateway”

Table 461: IO Provider / Consumer Status
“Application stop –> Substitute values”	When the user stops the application, the provider state for the output data sent by the controller is set to "BAD". Then the slaves set the inputs and outputs to predefined substitute values. For more information, see "CODESYS Default values – PROFINET Substitute values" at the end of this chapter.
“Add to I/O mapping”	: 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.
“Substitute Input-Data”	“Zero” “Last valid value” If a device does not provide valid input data, then the values (%I) in the local controller application are optionally reset or retain their last valid value

Table 462: Port Data
“Peer station/port”	Neighboring device with port that is connected to this port. You can accept this setting on the “ PROFINET Controller Topology” tab.
“Check cable length”	Length of the network cable (in meters) < 10 < 25 < 50 < 100 When the cable length is specified, it is checked when the controller is powered up. An incorrect cable length causes an error message.
“Transmission rate”	Transmission rate of the connection
“Disable fixed rate / autonegotiation”	: The transmission rate is fixed, automatic detection (autonegotiation) is disabled.
“DCP Boundary”	: DCP multicast messages (`‎Identify‎`, `‎Hello‎`) are not forwarded.
“PeerToPeer Boundary”	: No LLDP messages are sent.
“Disable port”	: The Ethernet port is completely disabled.

Table 463: Watchdog
“Enable”	Note: Available for AC500 communication module only. : If the AC500 communication module firmware is not set within the given time (for example, in the case of an exception error in the application), then it is reset. The connection is terminated and the slaves switch to their substitute values. The defaults for the watchdog originate from the device description.
