Передача Счетчиков по Modbus TCP
«ПульсХАБ» поддерживает передачу статистики каналов по протоколу Modbus TCP и Modbus RTU.
Подробное описание регистров Modbus содержится в руководстве по эксплуатации «ПульсХАБ».
Принятые показания счетчиков можно передать в базу данных, использовать для on-line мониторинга, управления и т.д.
