What is ClassicLadder?
- Two languages available : Ladder and Grafcet (Sequential) as used on many PLC for programming automation process. Ladder language allows to realize programs on PLC in an electric way. - Interpreted, not compiled - Programs splitted in sections (some can be sub-routines to call) - Events log of variables wanted to spy - Remote alarms (SMS with GSM modem, emails) - Full graphical editor (witch copy/paste function and search function) - Symbols - Real-time possibilities (RTLinux, RTAI, Xenomai) - Embedded possibilities (no GUI and number of objects parametrable to reduce memory use) - "Monitor" function to be able to connect to a remote target (on IP/UDP network, serial link and modem) + send/receive project - Hardware inputs/outputs support (parallel port on Linux/Windows, modbus serial RTU & IP, Linux Comedi drivers, RaspberryPi GPIOs) Modbus/TCP server for connection with scada
