-Danfoss АК-СС 550 refrigeration controllers are very popular devices applied in industrial cooling units. ​ 
  
 Increasing demand for the refrigeration quality ( keeping optimal product storage temperature) and efficiency (minimizing power consumption) enforces introduction of the scada/​monitoring systems which would helped to track malfanctions in time, detect abnormal situation and operation modes, provide analityics for resousrce consumption,​ or even optimize resource consumption using different strategies. ​ Increasing demand for the refrigeration quality ( keeping optimal product storage temperature) and efficiency (minimizing power consumption) enforces introduction of the scada/​monitoring systems which would helped to track malfanctions in time, detect abnormal situation and operation modes, provide analityics for resousrce consumption,​ or even optimize resource consumption using different strategies. ​

   * autosetup for baud rate - i.e. after the module detect 3 polls not matching own communication speed, it will change own uart's transmission rate to next option [9600, 19200, 38400]. ​ Thus WebHMI connection may have one of these 3 speed in its settings. ​   * autosetup for baud rate - i.e. after the module detect 3 polls not matching own communication speed, it will change own uart's transmission rate to next option [9600, 19200, 38400]. ​ Thus WebHMI connection may have one of these 3 speed in its settings. ​

 Параметры прибора в руководстве пользователя имеют буквенно-цифровой код, например r14, u11. Эти коды точно также отображаются на индикаторе прибора. Сетевой адрес модуля выставляется в параметре о03. Для получения Modbus адреса параметра необходимо определить его PNU номер (Parameter number) и вычесть из него 1. Полный перечень параметров и соответствующих PNU номеров приведен в документе AK-CC550 Modbus Parameter Definitions. Данный документ доступен по запросу [info@webhmi.com.ua]. Фрагмент таблицы параметров представлен ниже. Параметры прибора в руководстве пользователя имеют буквенно-цифровой код, например r14, u11. Эти коды точно также отображаются на индикаторе прибора.

 +Instrument parameters in the user manual have an alphanumeric code, for example r14, u11. These codes are also displayed on the instrument display. The network address of the module is set in parameter o03. To obtain a Modbus parameter address, one have to subtract 1 from PNU number (Parameter number). A complete list of parameters and the corresponding PNU numbers is given in AK-CC550 Modbus Parameter Definitions. This document is available on request . A fragment of the parameter table is presented below.
