PROFIBUS made simple Description The VPCLS2 handles all communication- and diagnosis-tasks of the PROFIBUS-DP-slave-protocol independently. No additional microcontroller or software is needed. All necessary timers and monitoring functions are implemented in hardware. Once the VPCLS2 receives an error-free telegram, it automatically generates the requested response telegram. This ASIC is therfore optimally suited for cost effective single-chip realizations of simple digital PROFIBUS I/O devices. Operation The PROFIBUS protocol is handeld by the integrated Microsequencer, a special...
