MDP-310.200
Radio Master Station
The MDP-310.200H acts as a radio modem and master station for radio networks with up to 64 slave stations: RTU-810 Radio Remote I/O Modules, TRM-810 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.].
Integrated Radio Monitor: This function records all radio data traffic, by which faults and errors can be diagnosed conveniently and precisely.
Interfaces and Protocols: The MDP-310 has two serial data interfaces (COM and AUX), user-configurable as RS-232 or RS-485/422. It also has an interface for PEM I/O Extension Modules. A Profibus DP interface is optionally available. Radio communication data is accessed using the MODBUS or MoP/MoP2 protocol. 3964R or the timeout protocol can be used as a Layer-1 protocol.
OPC Server strong>software is available to enable Windows based SCADA and other applications to access data from the radio network.
MDP Config: This Windows based configuration and programming software tool is supplied as standard with each unit. It allows radio communication parameters (frequency, RF power output level, etc.) to be easily set up in the MDP-310 from a PC.
PiRangia: This PC Windows based software tool allows easy configuration of the MDP-310 from a PC, to set up autonomous I/O transfer linkages among stations.
