Thanks to their wide scope of functions, the interface modules of the scalable SIPLUS extreme RAIL ET 200SP I/O system, even in their basic versions, cover a wide range of applications. The basic functions of the interface modules include:

• Approved in accordance with the railway standards EN 50155, EN 15121, EN 50124, EN 50125 and EN 45545 for use in rail traffic
• Short data update times of typically 1 ms
• Single Hot Swap (withdrawing and insertion of an I/O module during operation without impairing the communication with the remaining modules)
• Operation with gaps (empty BaseUnits)
• Complete diagnostic support, extending to channel-by-channel diagnostics
• Configuration control / option handling (adaptation of the actual configuration via user software)
• Device replacement without PG I&M data 0 to 3 (electronic rating plate with non-volatile storage of plant data)
• Firmware update
• Pluggable 24 V DC supply connection
• Network / power failure bridging time of 5 ms
• Labeling option via optional labeling strips and equipment labeling plates

When using PROFINET interface modules, the following basic functions are also included:

• Media redundancy (MRP) integrated 2-port switch
• Freely selectable connection method via SIMATIC BusAdapter
• Reset button for simple return to factory settings without the need for programming device
• Replacement without programming device even in case of non-topological configuration with subsequent automatic launching
• Automatic synchronization of the backplane bus to the PROFINET cycle to minimize the response time fluctuations (jitter)
