12、mm Protocol） AL175NTWinPower （pComm Protocol） MCU1.2 PurposeThe purpose of this document is to specify the message sequences and message definitions used in the communication protocol between the WinPower pc application and AL175NT/MCU power supply system. The messages that are similar for the two s

13、ystems have the same signal number. When MCU was developed, some changes was done in the pcomm protocol. All the messages that were changed resulted in a double set of messages （different signal numbers and data values in al175NT and MCU） for that particular command. All the changes （expandation of

14、existing messages and new messages）. The messages in MCU that differs from the messages in al175NT have got new signal numbers, and the messages for al175NT have kept the old signal numbers to keep the Winpower system compatible with old al175NT systems. Changes between the two systems are marked in

16、ocument describes the message sequences between the different modules in general, then a detailed signal description of each message is following. 2.1 GeneralThe pComm protocol TBDThe voltage ranges specified in some of the messages, are defined with respect to 48V systems. To calculate the same ran

17、ges for different systems the following conversion has to be done: - 24V system : Divide by 2- 12V system : Divide by 4- 60V system: Multiply by 5/4Example 48V system:DataHiAlarmWORD5000-6000d High Battery alarm （V） *Example 24V system:2500-3000d The software in AL175 can not store floating point va

18、riables. To deal with this, the variables that require better solution are multiplied by a factor of nx10, where n is the number of decimal points. These places are noted with one * pr decimal.2.1.1 Bits and byte orderThe order of bits and bytes is common for the different message definitions.The tr

19、ansmitted messages will have the following order of the bit and bytes:Bit 0-7 will contain the least significant byteBit 8-16 will contain the most significant bytemsb lsb msb lsb15141312119Most significant byte least significant byte Transmitted first3 General Message FORMATS3.1 PC-LinkAll messages

25、PriorityThe following priorities are used:High = 2hNormal = 8hLow = DhBy default priority is “Normal”.3.1.1.2 Quality of signal （QoS）The quality of signal parameter indicates how to operate on the data when receiving a message frame.Bit 3Acknowledge = 1, Unacknowledge = 0Bit 2With data = 1, Without

26、data = 0Bit 1Immediate response （destructive） = 1, Priority queue = 0Bit 0Reserved for later implementationsThe Immediate response QoS will trigger destructive mode. This will imply that queued entries with same priority will be destroyed.Initially we will not use the QoS bits and this word will be hardcoded to 0 （zero）.That means Quality of Signal will be: Unacknowledge = 0 Without data = 0 Priority queue = 03.1.1.3 Signal identifierThe signal identifier parameters are listed in chapter 4.33 3.1.2 Address （SA, DA）Addresses are represented as 8-bit ShortInt/Byte, with ranges from 1 to
