Barchard Engineering Ltd. supplies and services Galvanic Gas Micro, Dresser, and Mercury instruments.
The Mercury Instruments Protocol Translator (PT Board) is an adapter board that is connected between the Mercury Instruments Instrument (RTU) and a Host SCADA system.
The PT Board allows various asynchronous serial protocols to communicate with all instruments that support Mercury Instruments Protocol (Mini-AT, ER, ERX, ECAT, Mini, Mini-Max, etc.). The PT Board will translate the Host’s protocol (e.g. Modbus) to Mercury Instruments Protocol and back again so the Host can communicate with a Mercury Instruments Instrument in its native protocol. The PT Board handles communications between the Host interface and the Mercury Instruments Instrument in a Master-Slave type fashion. The PT will only respond to commands from the Host (master). These commands will be translated and sent to the Mercury Instruments Instrument (slave) as required.
