Connect Remotely

You can connect to a controller from an external network using VPN or other tunneling protocol.

You must open these ports which are used by KAS to connect to a controller:

Port	Component / Protocol Using the Port
80	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: Controller Web Server Download PLC "Programmable Logic Controller" A Programmable Logic Controller, PLC, or Programmable Controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events application Runtime In computer science, runtime (or run-time) describes the operation of a computer program, the duration of its execution, from beginning to termination (compare compile time). Within KAS, runtime also refers to the virtual machine that manage the program written in a computer language while it is running front end communication. This is necessary for the connection to the runtime In computer science, runtime (or run-time) describes the operation of a computer program, the duration of its execution, from beginning to termination (compare compile time). Within KAS, runtime also refers to the virtual machine that manage the program written in a computer language while it is running. If port 80 is used by any other application, the Simulator uses an alternate port available in the host computer for HTTP communication.
502	HMI "Human-machine interfaces " Also known as computer-human interfaces (CHI), and formerly known as man-machine interfaces, they are usually employed to communicate with PLCs and other computers, such as entering and monitoring temperatures or pressures for further automated control or emergency response and other 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) devices to communicate with Modbus TCP.
2222	EtherNet/IP communication.
4002	KAS-IDE: Oscilloscope variable monitoring.
4003	KAS-IDE: Communication with the PLC Virtual Machine. This is necessary for the connection to the runtime.
9900	KAS-IDE: Communication with the runtime engine; WorkBench views. This is necessary for the connection to the runtime.
34962	PROFINET communication.
34964	PROFINET communication.
44848	EtherNet/IP communication.
