Extension of an interface You can extend interfaces just like function blocks. The interface is then also given the interface methods and interface properties of the basic interface in addition to its

Working with Controller Networks With the following functionalities, CODESYS supports communication between controllers (PLC) and the insertion of a safety controller below a PLC: Symbol Configuration

Network and Addressing Constructing a control network hierarchically, so that extensive self-configuration is possible. In CODESYS , the network topology is mapped to unique addresses and the routing

Network Topology Information and recommendations for the topology of a control network It is recommended to set up a network system so that the following are possible: Extensive self-configuration (ad

Addressing and Routing Addressing means: the topology of the control network is mapped to unique addresses. A node address is composed hierarchically: For each network connection the associated block

Address Structures Network addresses Network addresses represent a mapping of the addresses of the network type (for example IP) to logical addresses within a control network. This mapping is performe

Network Variables The values of network variables can be exchanged between different PLCs in a network. The variables have to be defined in rigid, identical lists in both the transmitter device and th

Configuring a Network Variable Exchange The following steps are necessary for exchanging network variables between the sender device and receiver device: 1. Creating a network variable list in the sen

Subordinate Safety Controller If a safety controller is below the standard controller, then the communication with the development system and the data exchange run via the standard controller. The com

Creating Comparison Views Requirement: You have made changes in your current project and want to compare it, for example, with the last saved version. In the meantime, you have, for example, added mor
