Profinet IO RT Controller Configuration

The KAS IDE "Integrated development environment" An integrated development environment is a type of computer software that assists computer programmers in developing software. IDEs normally consist of a source code editor, a compiler and/or interpreter, build-automation tools, and a debugger contains a fully integrated configurator for Profinet IO RT Controller.

The Profinet maximum data size is 1440 bytes Input length and 1440 bytes Output length. To calculate the size, use the slot configuration view to count the number of bits per slot and convert to bytes. For example, 7 slots containing 16 outputs of 32 bits each, would be 7 * 16 * 32 = 3584 bits = 448 bytes.

• Referring to the Profinet standard, the units of a Profinet network are named as IO Controllers (Masters) and IO Devices (Slaves).

• To use some of the additional features of the Profinet controller fieldbus editor, such as “Browse Network for Slaves”, you need to install the "CD Prot" driver. The installer can be found in <Kollmorgen Automation Suite installation directory>\Bin\CDProtDriver.

  Please note that your computer will need to be rebooted after installing the driver.

• Profinet is only supported on AKD PDMMs and PCMMs.

• Unlike an EtherCAT ***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs fieldbus which has a dedicated Ethernet Ethernet is a large, diverse family of frame-based computer networking technologies that operate at many speeds for local area networks (LANs) interface, the Profinet fieldbus communicates through the same Ethernet interface as Modbus ModBus is a serial communications protocol and is now the most commonly available means of connecting industrial electronic devices. ModBus is often used to connect a supervisory computer with a remote terminal unit in supervisory control and data acquisition (SCADA) systems. Versions of the ModBus protocol exist for serial port and Ethernet (it is widely used with TCP/IP over Ethernet) and other non-fieldbus communication. There is no prioritization of Profinet over the other communication protocols, so frequent HTTP or IDE Oscilloscope communication can cause delay in the Profinet communications, and ultimately Profinet frame loss.
