CPU & POWER MODULES
Bus connection and power supply for flexible use
The CPU modules for the IS1+ system support the most common communication protocols, such as PROFIBUS DP, PROFINET and EtherNet/IP. Copper cables or fibre optics are used for communication, and system redundancy can also be added.
The power module provides an intrinsically safe power supply and, like any other module, can be connected and disconnected in hazardous areas.
IS1+ CPU & power modules supply up to 16 I/O modules with intrinsically safe power and connect to all common automation systems.
RS485, or RS485-IS in Zone 1, is used for communicating via PROFIBUS DP and Modbus RTU. Fast, interference-free “Ex op is” 100 MBit/s fibre optics are used for the Industrial Ethernet connection via Modbus TCP, EtherNet/IP and PROFINET. System redundancy or integration into an optical ring to increase availability can also be supported, depending on the protocol.
A wide range of diagnostics is available either via a separate service bus or via the relevant process bus. These diagnostics can be easily integrated into plant asset management systems by an effective DTM.
