1 INTRODUCTION This paper describes Profibus DPV0 Protocol for UNISAB II in an extended version compared to the Tiny Profibus Protocol also available for UNISAB II. This Extended version provides all analog values, mode, state, control-on-value, capacity set point, active timer number and value, digital inputs and digital outputs as well as cause of alarm and up to 2 warnings. All this is updated continuously. Writing start/stop command, changing control-on-value, mode, setup for sequencing and capacity set point is also featured using continuous updating. All values, limits and settings in the databases of the UNISAB II holding measurements data, timer data config data and alarm loggings are available using a command answer method. Some of these limits and settings can be written to, also using the command answer method. UNISAB II will prevent writing values beyond certain limits for safety reasons. The transport mechanism (layer 1 and 2) is strictly according to standard Profibus DPV0 Protocol standards. The application layer (layer 7) is presented in this paper. The application layer for UNISAB II is based on the two papers listed below but it does not comply to any of those in detail. PROFIBUS Profile Profile for SEMI Version 1.0 August 2002 PNO Order No. 3.152 PROFIBUS Profil Profil fr Drehzahlvernderbare Antriebe, PROFIDRIVE Ausgabe September 1997 PNO Best.-Nr. 3.071



2 PROTOCOL IN DETAIL

2.1 What is PPO Parameter-Prozessdaten-Objekt (Parameter-Process data-Object) is comprised of the PKW (please see chapter 3) plus PD (Prozessdaten). PD hold the data that are changed constantly and which should be transferred cyclically. This means that this data is transferred in each transmission from master to slave and from slave to master. In the present version of the protocol only PDR1 and PDR2 is implemented.

3 DATASTRUCTURE OF TELEGRAM Using 8 bytes it is possible to transfer data to and from UNISAB II in acyclic mode. This method is not exactly according to the profiles referred to in chapter 1 but it does not differ much. Most notable is the database and datapoint terms which are used in place of PNU (Parameter Number). 0 1 2 3 4 5 6 7 8 9 Etc. PKE PKE IND Res. PWE PWE PWE PWE Rest of Telegram PKE = Parameter Kennung = parameter signature PKW = Parameter Kennung Wert = PKE + IND + PWE IND = index in the data structure Res = Reserved for later extensions PWE = Parameter Wert = Parameter value (Only Byte 7 used for bytes data, byte 6 and 7 are used for Integers and byte 4, 5, 7 and 7 are used for Longint data) Rest of Telegram = Cyclic part of transmission

Response signature will be returned in the AK field. To secure the Unisab II response match the request, check the header content is identical for the answer and the request.

3.3 Error codes If UNISAB II cannot return the data wanted or cannot write the settings wanted an error code is returned in the PWE field byte no 6 and 7 as one integer.

0 Undefined PNU 1 Parameter cannot be written into 2 Value outside low or high limit 3 Index error

3.4 PKW points in UNISAB II PKW (PARAMETER-KENNUNG-WERT) Data in UNISAB II is stored in simple databases using structures. This makes tables and addressing simpler than having one long numbered array of data. Furthermore it makes later extensions of these databases and their structures possible without compromising compatibility towards newer or older versions. If master indexes too far in an old slave the slave will respond with an error message telling that this point is not defined. (Error code 0). This demands that the numbering of existing points and indexes must never be altered in UNISAB II versions to come. HOW TO: There are several databases, each with data points of different structure. The database is addressed with bit 8, 9 and 10 of the PKE. The 8 LSB of the PKE is the actual data point number in the database in question. With IND (Index) of the PKW the structure is indexed into. Please note that index 0 in MEASUREMENTS DATA are all transferred in the PZD (Prozessdaten) field of the PPO (Parameter-Prozessdaten-Objekt) using cyclic transfer. This might be useful for testing. Please note that all data is transferred as integers. Data structures which are not composed of integers must nevertheless be accessed as arrays of integers.

The same data structure is shared for all data points, even it for some data dont make any sense. If an entry is read where the value would be undefined, the returned value will be 0. If you try to write to an undefined value, the error code out of range will be returned for all value (exception: If you write 0, no error code will be returned). Addressing beyond index 46 is not considered to be relevant. If you want to do so anyway you must transfer the data needed as integers and figure out in which way to unpack data. Later there may be added definitions about sub structures MENU_FLAG_REC etc. This is not considered relevant now as this information is of no use outside UNISAB II except for debugging software internally to UNISAB II.

3.6.5 Data structure of EEPROM DATA:

Please note that all data in EEPROM DATA is one data structure. This means that there is only one data point i.e. number zero. unsigned char sec; /* Seconds */ 0 unsigned char min; /* Minutes */ 0 unsigned char hour; /* Hour */ 1 unsigned char mday; /* Day of month */ 1 unsigned char month; /* Month */ 2 unsigned char year; /* Year */ 2 unsigned long compr_ser_no; 3 and 4 unsigned int next_alarm_log; 5 unsigned int total_number_of_alarms; 6 0 2 is Time for Commissioning



Next_alarm_log is the data point that will be written into with data of the next alarm to occur. So the most recent alarm log is next_alarm_log minus one.

3.6.6 Data points in ALARM LOG DATA:

Simply an array of data structures 0..29. Please note note that the alarms are being logged into a ring buffer system consisting of these 30 logs. The eldest one may any time be overwritten while You are fetching its data if a new alarm occurs. Date and time of the log being read may be used for checking that it has not been updated while reading the rest of that log. Please use the date and time of each log for sorting the logs chronologically. Or use the total_number_of_alarms and next_alarm_log from the EEPROM DATA.

3.6.6.1 Data structure for ALARM LOG DATA:

unsigned char (8 bit)* al_type; /*30-73*/ 0 unsigned char (8 bit)* year; /*0=1992. 99 = 2091*/ 0 unsigned char (8 bit)* month; /*1-12*/ 1 unsigned char (8 bit)* day; /*1-31*/ 1 unsigned char (8 bit)* hour; /*0-23*/ 2 unsigned char (8 bit)* min; /*0-59*/ 2 unsigned char (8 bit)* mode_status; /*hi mode 0-4 lo nibble status 0-11*/ 3 unsigned char (8 bit)* start_system_no; /*hi start_no 0-14 , lo system_no 0-14*/ 3 unsigned char (8 bit)* multisab_state; /*0-9*/ 4 unsigned char (8 bit)* dig_i_00_07; 4 unsigned char (8 bit)* dig_i_08_15; 5 unsigned char (8 bit)* dig_o_00_07; 5 unsigned char (8 bit)* dig_o_08_15; 6 unsigned char (8 bit)* dig_o_16_23; 6 unsigned int (16 bit) runtime; /*0-0xffff*/ 7 unsigned long (32 bit) latest_runtime; /*seconds*/ 8 and 9 int s_temp; 10 int d_temp; 11 int o_temp; 12 int b_i_temp; 13 int s_press; 14 int d_press; 15 int lub_press; 16 int d_i_press; 17 int vol_pos; 18 int cap_pos; 19 int ext_inp; 20 int motor_curr; 21 int s_superheat; 22 int d_superheat; 23 int motor_power; 24 int motor_revs; 25 * How to unpack unsigned char: If you read the number 0E2B HEX, the value must be splitted up in 2 part say 0E2B -> 0E and 2B is the wanted values. Imagine the above value was the alarm type, the values represented is: 0E Hex is the year calculated from 1992 > year = 2006 2B Hex is the alarm type = 43

Its located at page 12 and is placed under MEASUREMENTS DATA. Using the figure as the basis for building the PKW (data address), we start from the top with the AK in PKE byte 0 and the walking down the bytes. PKE byte 0: AK: We want to read the value -> AK = 1 SPM: not implemented -> SPM = 0 Database: Brine temp is located in the Measurement Data -> Database = 0 Figuring out PKE byte 0: AK is four bits and = 1 -> 0001 SPM one bit and = 0 -> 0 Database is 3 bits and = 0 -> 000 PKE byte 0 = 00010000 bin = 10 Hex PKE byte 1: Data point: the data point entry for Brine temp is 9 -> data point = 9 PKE byte 1 = 9 = 00001001 bin = 09 Hex

Sending this to the Unisab II Profibus, provide us with the wanted information regarding Brine setp1 Where to read the data Brine setp 1 is an integer, and the response will be returned in PWE 6 and PWE 7* * If the data cant be returned, an errorcode is returned in PWE 6 and PWE 7. Please refer to page 11 for more details



4.2 Example 2: Reading Running hours Wanted parameter is Running hours (communication from Unisab II to master). First step is to find the Running hours parameter in this documentation. Its located at page 19 and is placed under RANDOM DATA. Using the figure as the basis for building the PKW (data address), we start from the top with the AK in PKE byte 0 and the walking down the bytes. PKE byte 0: AK: We want to read the value -> AK = 1 SPM: not implemented -> SPM = 0 Database: Running hours is located in RANDOM Data -> Database = 6 Figuring out PKE byte 0: AK is four bits and = 1 -> 0001 SPM one bit and = 0 -> 0 Database is 3 bits and = 6 -> 110 PKE byte 0 = 00010110 bin = 16 Hex PKE byte 1: Looking at page 19, we can see that the datapoint entry for Running hours is 0 -> datapoint = 0 PKE byte 1 = 0 = 0000000 bin = 00 Hex

IND: The datastructure for random data is located at page 23. The running hour is the type value -> Index = 0 = 00000000 bin = 00 Hex Where to read the data From the random data information table at page 23, you can be informed that the Running hours data type is Longint, which is a 32 bit data type. Be aware that for running hour values beyond 2^16 (65536), 4 bytes must be read. 32 bits total located at PWE byte 4 + 5 + 6 + 7(with PWE 7 representing LSB).

4.3 Example 3: Reading alarms In this example we will read the newest alarm, and after this fetch an old alarm. Say we want to read the newest alarm which is a High Discharge Pressure alarm. But of course we dont know the type of alarm before we have read the alarm type, so lets find out how we do read alarms. Finding the newest alarm As explained on page 18, the alarms will be put into a ring buffer (maximum 30 alarms), where the oldest alarm will be deleted when a new alarm arrive. To get the newest alarm location in the alarm buffer, read the parameter next_alarm_log. This parameter tells where the next upcoming alarm will be placed. The location for the newest alarm is then next_alarm_log minus 1. To read the location we must define the PKE byte 0, PKW byte 1 and the index. PKE byte 0: AK: We want to read the value -> AK = 1 SPM: not implemented -> SPM = 0 Database: the location is located in EEPROM Data -> Database = 4 Figuring out PKE byte 0: AK is four bits and = 1 -> 0001 SPM one bit and = 0 -> 0 Database is 3 bits and = 4 -> 100 PKE byte 0 = 00010100 bin = 16 Hex

PKE byte 1: Looking at page 17, the text explains theres only one data point having the number 0 -> datapoint = 0 PKE byte 1 = 0 = 0000000 bin = 00 Hex IND: The data structure for EEPROM Data is located at page 17. Finding Next_alarm_log -> Index = 5 = 00000101 bin = 05 Hex Where to read the data Next_alarm_log is an integer, and the response will be returned in PWE 6 and PWE 7*. If the response is 18, you now know the latest alarm is placed at location 17 in the ring buffer. Please do remember this number, because you have to use it as PKE byte 1, when you pick up the alarm information. * If the data cant be returned, an error code is returned in PWE 6 and PWE 7.

Reading the newest alarm Now we know where to fetch the data, and are able to get the data. The first information we want from the alarm, is the alarm type. To read the alarm, we must define the PKE byte 0, PKW byte 1 and the index. PKE byte 0: AK: We want to read the value -> AK = 1 SPM: not implemented -> SPM = 0 Database: the location is located in ALARM LOG Data -> Database = 5 Figuring out PKE byte 0: AK is four bits and = 1 -> 0001 SPM one bit and = 0 -> 0 Database is 3 bits and = 5 -> 101 PKE byte 0 = 00010101 bin = 16 Hex PKE byte 1: This is where you will use the information about the alarm number found just before. We did get 18 as return value and the new alarm is placed at location 18 1 -> 17. PKE byte 1 = 17 dec = 00010001 bin = 11 Hex

IND: The datastructure for ALARM LOG Data is located at page 18. We want to read the alarm type, which is the parameter called al-type. To read the alarm type you must set the index to 0. -> Index = 00 Hex Where to read the data al_type is an integer which is combined with the info of the year for the alarm, and the response will be returned in PWE 6 and PWE 7* How to extract data If you read the index 0, lets say the returned value is 0E24. The data can be split up as: First part is al type and second part is the year for the alarm event. In the example we get: Al_type = 24 hex = 36 dec Year for the alarm = 0E hex = 14 dec The alarm information is:

1. High Discharge Pressure alarm (alarm type 36) 2. Year for the Unisab II alarm event is 1992 + 14 = 2006.

To read the additional data from the alarm, repeat the PKE byte 0 and PKE byte 1 settings from the above example, but change the IND (index) to obtain the wanted parameter. To see all the available parameters, please look at page 14 How to read the other alarms If you want information from other than the newest alarm, you can follow the same practice as the above example, but change the calculation from the newest alarm to the alarm you want to read. If you want the third latest alarm, you just calculate the new PKE byte 1 value as: New alarm 3. The only change from the above example is another PKE byte 1 number, selecting the wanted alarm. How to discover when a new alarm arrives If you want to discover when new alarms arrive, you can make a read cycle of the next_alarm_log number (reading of the next_alarm_log parameter, is the first part of the above example). When a new alarm occurs, this number will increase and you know a new alarm has arrived.

4.4 Example 4: Write Capacity Setpoint Wanted parameter is the Capacity Setp1 (communication from Master to Unisab II). First step is to figure out the data/value which has to be written to the Unisab II. A legal value will be a number between Capacity setp1min and Capacity setp1max. Range of legal values will depend on the actual Unisab II configuration. To make sure a legal value is selected, the Capacity setp1min and Capacity setp1max values can be read. In this example a value of 1011100110 bin = 2E6D HEX (742 decimal) is chosen. When doing this in real, please make sure this value is inside the legal value range for your system, by reading setp1min and setp1max values. The value written to Unisab II must be put at PWE 6 and PWE 7 as: PWE 6 = 00000010 PWE 7 = 11100110

If the data cant be written, an error code is returned in PWE 6 and PWE 7. Please refer to page 11 for more details To examine the data has been written to the Unisab II, try to read the Capacity Setp1 value and compare the result with the written value (hopefully they are equal to each other).



4.5 Example 4: Writing timer for prelub. Wanted parameter is the timer for the prelubriation pump Prelub (communication from Master to Unisab II). * Please note that prelubriation functionality isnt present at all compressor installations. First step is to figure out the data/value which has to be written to the Unisab II. A legal value will be a number between Prelub setMIN and Prelub setMAX. Range of legal values will depend on the actual Unisab II configuration. To make sure a legal value is selected, the Prelub setMIN and Prelub setMAX values can be read. In this example a value of 11001100111101 bin = 333D HEX (819 decimal) is chosen. For practical test purposes, please make sure this is inside the legal value range for your system by reading setMIN and setMAX values. The value written to Unisab II must be put at PWE 6 and PWE 7 as: PWE 6 = 00110011 PWE 7 = 00111101
