Even using reliable, industry-proven components, production line failures can occur, potentially having a critical impact on production. Therefore, manufacturers must assess system availability to identify single points of failure and find solutions that reduce the risk of downtime. By introducing redundancies, the availability of the automation system can be significantly increased.
If it is necessary to improve the availability of sensor and/or actuator loops, this application offers effective solutions. By incorporating redundancy in the I/O modules connected to individual or redundant sensors/actuators, the availability of these loops is significantly improved.
Thanks to the monitoring performed by the “LRedIo” function blocks, even in the event of a failure of an I/O module or channel, the automation system will continue to operate, ensuring that the customer’s process is not affected.
The LRedIo library contains standard function blocks (FBs) for implementing applications with redundant I/O modules using SIMATIC S7-1500 CPUs. This library is compatible with all SIMATIC S7-1500 CPUs, including the S7-1500R/H redundant controllers.
