The LCom library implements a point-to-point connection in both directions (full duplex) between two devices. The function block can be used for standard TCP communication. The widespread deployment of the TCP standard allows data exchange to be implemented between two different devices. All types of controllers and devices that have an Ethernet interface and support the TCP protocol can be connected, e.g. cameras, printers, scanners and PCs. Since the functional scope of TCP is not sufficient for many applications, the LCom library defines a separate transport protocol (the LCom protocol). The LCom protocol can be activated if the communication partner supports the LCom protocol too. If not, the native TCP communication can be used. The following additional functions are supported by LCom protocol: Data records with defined length up to 16 MB (with V1 up to 64 kB possible) Different transmission modes. (cyclic, at data change or once) Monitoring of the connection through cyclic transmission of a sign-of-life (faster response times on connection failure). In the case of a pure TCP communication, this is typically in the range of seconds. Prevention of a full working memory on the system level through frequent sending of data via integrated flow control on the application level. Feedback from receiver on successful data transmission on application level. Simple time synchronization. Data transport in both transmission directions can be started and stopped by both communication peers.
