The Ethernet system with protocol interpreter function MSX-E7511 has 4 serial interface ports for RS232, RS422, RS485 or TTY (20 mA Current Loop). It allows to filter the actual user data from the protocol and to transmit only this data or to store it in a database. The acquired data of all interfaces can be calculated onboard with the ARM®9 32-bit processor. Furthermore, the system can send commands to output systems of the MSX-E series and can thus be used as a self-sufficient unit in the harsh industrial environment. It has a robust normed metal housing with the degree of protection IP 65 and an extended temperature range from -40°C to +85°C. The Development Mode allows to customise applications individually. Through synchro connection, several MSX-E systems can be daisy-chained and synchronised with one another in the µs range.
