| Öğe açıklaması | Communications processor / the PMC-1304-3 is the ideal embedded equipment for connecting RS-422 or RS-485 enabled serial devices to an IP-based LAN, making it possible for scada or other applications to access serial devices over a LAN for monitoring and control applications. The PMC-1304-3 has been specifically designed with industrial automation in mind and therefore provides un-surpassed performance and reliability under the harshest industrial environments. The basic model, PMC-1304-3-T, provides MODBUS gateway function from MODBUS TCP to rtu and supports interrogation from multiple MODBUS masters. The optional rtu model, PMC-1304-3-R, provides MODBUS mastering capability with local data caching and logging to enhance overall system performance and redundancy. Not only does the rtu model support the polling of real-time data, it also supports the uploading of data logs, event logs an |
