ProTalk 100 is a Supervisory Control and Data Acquisition (SCADA)
protocol converter for Modbus devices. This module is used to provide a
connection to other systems using a communication protocol, such as
Conitel, PERT 26/31, CDD II or any one of many other protocols. The
ProTalk 100 emulates the communications protocol of the Master, allowing
a standard Modbus device to be used as a Remote Terminal Unit (RTU) in
any SCADA system.
The ProTalk 100 has a built in Bell 202 modem which can communicate with a SCADA master in either 2 wire or 4 wire configuration. The ProTalk 100 communicates with the Modbus device over an RS-232 communications link.
A windows based program is provided with the ProTalk 100 to allow data to be mapped between the Modbus protocol and the SCADA protocol. The data map is downloaded into non-volatile memory in the ProTalk 100.
