Radio modem
410 - 470 MHz, 0.1 - 6 W, max. 64 station | MDP-310.200H Funk-Electronic Piciorgros

The MDP-310.200H acts as a radio modem and master station for radio networks with up to 64 slave stations: RTU-710 Radio Remote I/O Modules, TRM-710 Serial- Interface Radio Modems, SS20F Solar Powered RTU Stations, and Local I/O Extension Modules (LIO's). The master station cyclically interrogates the slave stations, storing the received data until it is collected by a locally interfaced central control system. The MDP-310 also acts as a radio gateway that allows its host control system to set outputs and read inputs at remote slave stations. The MDP-310 does all this transparently so that the control system is relieved of the complexities of radio communications, slave station polling and radio network management.

Extended routing: The MDP-310 can communicate with any slave station directly or indirectly via a chain of up to 31 other slave stations additionally functioning as radio repeaters.

Virtual I/O Linking Function: The MDP-310 can act as a "virtual I/O patch panel" through which up to 300 dedicated virtual links can be set up for autonomous transfer of I/Os among slave stations. Each link enables an input at one station to be reproduced as an output at another station, autonomously of the host control system. I/O information is at the same time made available to the control system for display, monitoring, supervisory control and alarm management functions.

Integrated Communications Logger: The MDP-310 features an integrated communications logging function that automatically records all occurrences of irregularities in radio traffic [e.g., lack of slave station response, radio reception loss, etc.].
