With the isNet PAMon module, any gateway built with the isNet Lite can be extended to operate as a PROFIBUS PA diagnosis and protocol monitor. The module helps to detect and investigate sporadic problems in the data transmission on a PROFIBUS line. Communication problems can be so easily captured and eliminated.
The PA Monitor module has two independently working channels, which are connected via screw terminals directly to the PROFIBUS PA lines. The diagnostic modules operate entirely passive, no telegrams will be sent to the PROFIBUS lines. Instead, the status of all PA slaves is detected and shown in a summary on a PC. In this illustration, the bus state for each of the individual layers of the OSI reference model is determined separately and can be selected individually.
The features of the isNet PAMon module include a protocol monitor, an evaluation of statistical data on the PROFIBUS, such as Error counters or average time intervals, and for investigation of the physical signal quality, the integrated oscilloscopes for every PA channel are quite useful. Even when no PC is connected to the Netlite, the module can still record protocol telegrams due to its long-term recording capability, the captured telegrams are stored on an SD card.
