TwinCAT® PLC
BECKHOFF
Software PLC for Windows NT/2000/XP/Vista
The TwinCAT PLC is programmed in accordance with IEC 61131-3 independently of the manufacturer. Online connections with PLC run-time systems around the world can be implemented with TCP/IP or via fieldbuses on the IPC.
TwinCAT PLC programming system
TwinCAT PLC offers all the languages in the IEC 61131-3 standard and has a powerful development environment for programs whose code size and data regions far exceed the capacities of conventional PLC systems.
Online connection via networks
Changes to programs or data are supported by a very powerful link to the run-time systems, which can also operate over a network. All the usual facilities of a PLC are available.
Any Windows programs, for instance visualisation programs or Office programs, can access TwinCAT data via Microsoft interfaces or control the PLC.
