1. IntroductionThis paper describes Profibus DPV0 Protocol for Unisab III in an extended version. The Exten-ded Protocol uses GSD file 095D. A Tiny Profibus Protocol using GSD file 08AA is also availablefor Unisab III. Refer to separate manual Unisab III Profibus specification_Tiny for descrip-tion of the Tiny Protocol.This Extended version provides all analog values, control mode, compressor state, multisabstate, control-on-value, capacity set point, active timer number and value, digital inputs anddigital outputs as well as cause of shutdown and up to 2 alarms. All this is updated continu-ously. Writing start/stop command, changing control-on-value, mode, setup for sequencingand capacity set point is also featured using continuous updating.All values, limits and settings in the databases of the Unisab III holding measurements data,timer data config data and shutdown loggings are available using a command answer meth-od. Some of these limits and settings can be written to, also using the command answermethod. Unisab III will prevent writing values beyond certain limits for safety reasons.GSD files, program examples and installation guides can be downloaded from www.sab-roe.comIf you need further information, please contact the Technical Support Controls office statedbelow.Johnson Controls Denmark ApSTechnical Support ControlsChristian X's Vej 201DK-8270 HjbjergDenmark

Introduction


2. Protocol in detail2.1. What is PPOParameter-Prozessdaten-Objekt (Parameter-Process data-Object) is comprised of thePKW (please see chapter 3) plus PD (Prozessdaten). PD holds the data that are changedconstantly and which should be transferred cyclically. This means that this data is transferredin 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 telegramUsing 8 bytes it is possible to transfer data to and from Unisab III in acyclic mode. This meth-od 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 (ParameterNumber).

Responsesignature will be returned in the AK field.To secure the Unisab III response match the request, check the header content isidentical for the answer and the request.

3.3. Error codesIf Unisab III cannot return the data wanted or cannot write the settings wanted an error codeis returned in the PWE field byte no 6 and 7 as one integer.

0 Undefined PNU1 Parameter cannot be written into2 Value outside low or high limit3 Index error

3.4. PKW points in Unisab IIIPKW (PARAMETER-KENNUNG-WERT)Data in Unisab III is stored in simple databases using structures. This makes tables and ad-dressing simpler than having one long numbered array of data. Furthermore it makes laterextensions of these databases and their structures possible without compromising compatibili-ty towards newer or older versions. If master indexes too far in an old slave the slave will re-spond with an error message telling that this point is not defined. (Error code 0). This de-mands that the numbering of existing points and indexes must never be altered in Unisab IIIversions to come.

HOW TO:

There are several databases, each with data points of different structure. The database is ad-dressed with bit 8, 9 and 10 of the PKE. The 8 LSB of the PKE is the actual data point numberin the database in question. With IND (Index) of the PKW the structure is indexed into.Please note that index 0 in MEASUREMENTS DATA is all transferred in the PZD (Prozessdaten)field of the PPO (Parameter-Prozessdaten-Objekt) using cyclic transfer. This might be usefulfor testing.Please note that all data is transferred as integers. Data structures which are not composed ofintegers must nevertheless be accessed as arrays of integers.

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 allvalue (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 anywayyou 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 notconsidered relevant now as this information is of no use outside Unisab III except for debug-ging software internally to Unisab III.

Data structure for CONFIG DATA and for EXTENDED CONFIG DATA:Actual value 0Min value 1Max value 2

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 onlyone data point i.e. number zero.

unsigned char sec; /* Seconds */ 0unsigned char min; /* Minutes */ 0unsigned char hour; /* Hour */ 1unsigned char mday; /* Day of month */ 1unsigned char month; /* Month */ 2unsigned char year; /* Year */ 2unsigned long compr_ser_no; 3 and 4unsigned int next_shutdown_log; 5unsigned int total_number_of_shutdowns; 6

0 2 is Time for Commissioning

Next_shutdown_log is the data point that will be written into with data of the next shutdownto occur. So the most recent shutdown log is next_shutdown_log minus one.

3.6.6 Data points in SHUTDOWN LOG DATA:

Simply an array of data structures 0..29.Please note note that the shutdowns are being logged into a ring buffer system consisting ofthese 30 logs. The oldest one may any time be overwritten while You are fetching its data if anew shutdown occurs. Date and time of the log being read may be used for checking that ithas not been updated while reading the rest of that log. Please use the date and time of eachlog for sorting the logs chronologically. Or use the total_number_of_shutdowns andnext_shutdown_log from the EEPROM DATA.

* How to unpack unsigned char:If you read the number 0E2B HEX, the value must be splitted up in 2 part say 0E2B -> 0E and2B is the wanted values. Imagine the above value was the shutdown type, the values repre-sented is: 0E Hex is the year calculated from 1992 > year = 2006 2B Hex is the shutdowntype = 43

4.1. Example 1: Reading a process out setp1.Wanted parameter is Process out setp1 (communication from Unisab III to master).First step is to find the Process out parameter in this documentation. Its located at page 13and is placed under MEASUREMENTS DATA.Using the figure as the basis for building the PKW (data address), we start from the top withthe AK in PKE byte 0 and the walking down the bytes.PKE byte 0:AK: We want to read the value -> AK = 1SPM: not implemented -> SPM = 0Database: Process out temp is located in the Measurement Data -> Database = 0

Figuring out PKE byte 0:AK is four bits and = 1 -> 0001SPM one bit and = 0 -> 0

Examples


Database is 3 bits and = 0 -> 000

Sending this to the Unisab III Profibus, provide us with the wanted information regardingProcess out setp1Where to read the dataProcess out setp 1 is an integer, and the response will be returned in PWE 6 and PWE 7*

Examples


* If the data cant be returned, an error code is returned in PWE 6 and PWE 7. Please refer topage 11 for more details

4.2. Example 2: Reading Running hoursWanted parameter is Running hours (communication from Unisab III to master).

First step is to find the Running hours parameter in this documentation. It is located on page25 and is placed under RANDOM DATA.

Using the figure as the basis for building the PKW (data address), we start from the top withthe AK in PKE byte 0 and the walking down the bytes.

PKE byte 0: AK: We want to read the value -> AK = 1SPM: not implemented -> SPM = 0Database: Running hours is located in RANDOM Data -> Database = 6

Figuring out PKE byte 0:AK is four bits and = 1 -> 0001SPM one bit and = 0 -> 0Database is 3 bits and = 6 -> 110

Where to read the dataFrom the random data information table at page 26, you can be informed that the Runninghours data type is Longint, which is a 32 bit data type. Be aware that for running hour valuesbeyond 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 shutdownsIn this example we will read the newest shutdown, and after this fetch an old shutdown.

Say we want to read the newest shutdown which is a High Discharge Pressure shutdown.But of course we dont know the type of shutdown before we have read the shutdown type, solet us find out how we do read shutdowns.

Finding the newest shutdown

As explained on page 21, the shutdowns will be put into a ring buffer (maximum 30 shut-downs), where the oldest shutdown will be deleted when a new shutdown arrive.To get the newest shutdown location in the shutdown buffer, read the parameter next_shut-down_log. This parameter tells where the next upcoming shutdown will be placed. The loca-tion for the newest shutdown is then next_shutdown_log minus 1.To read the location we must define the PKE byte 0, PKW byte 1 and the index.

Examples


PKE byte 0:AK: We want to read the value -> AK = 1SPM: not implemented -> SPM = 0Database: the location is located in EEPROM Data -> Database = 4

Figuring out PKE byte 0:AK is four bits and = 1 -> 0001SPM one bit and = 0 -> 0Database is 3 bits and = 4 -> 100

Where to read the dataNext_shutdown_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 shutdown is placed at location 17 in the ringbuffer. Please do remember this number, because you have to use it as PKE byte 1, when youpick up the shutdown information.

* If the data cant be returned, an error code is returned in PWE 6 and PWE 7. Please refer topage 11 for more details

Reading the newest shutdownNow we know where to fetch the data, and are able to get the data. The first information wewant from the shutdown, is the shutdown type. To read the shutdown, we must define thePKE byte 0, PKW byte 1 and the index.

PKE byte 0:AK: We want to read the value -> AK = 1SPM: not implemented -> SPM = 0Database: the location is located in SHUTDOWN LOG Data -> Database = 5

Figuring out PKE byte 0:AK is four bits and = 1 -> 0001SPM one bit and = 0 -> 0Database is 3 bits and = 5 -> 101PKE byte 0 = 00010101 bin = 16 Hex

IND:The datastructure for SHUTDOWN LOG Data is located at page 21. We want to read the shut-down type, which is the parameter called al-type. To read the shutdown type you must setthe index to 0.-> Index = 00 Hex

Bit 1Bit 2

0000000

Where to read the dataal_type is an integer which is combined with the info of the year for the shutdown, and theresponse will be returned in PWE 6 and PWE 7*

How to extract dataIf 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 shut-down event. In the example we get:

Al_type = 24 hex = 36 decYear for the shutdown = 0E hex = 14 dec

The shutdown information is:1. High Discharge Pressure shutdown (shutdown type 36)2. Year for the Unisab III shutdown event is 1992 + 14 = 2006.

To read the additional data from the shutdown, repeat the PKE byte 0 and PKE byte 1 settingsfrom the above example, but change the IND (index) to obtain the wanted parameter. To seeall the available parameters, please look at page 21.

Examples


005261 en 2013.12

How to read the other shutdownsIf you want information from other than the newest shutdown, you can follow the same prac-tice as the above example, but change the calculation from the newest shutdown to the shut-down you want to read. If you want the third latest shutdown, you just calculate the new PKEbyte 1 value as: New shutdown 3. The only change from the above example is anotherPKE byte 1 number, selecting the wanted shutdown.

How to discover when a new shutdown arrivesIf you want to discover when new shutdowns arrive, you can make a read cycle of thenext_shutdown_log number (reading of the next_shutdown_log parameter, is the first part ofthe above example). When a new shutdown occurs, this number will increase and you know anew shutdown has arrived.

4.4. Example 4: Write Capacity SetpointWanted parameter is the Capacity Setp1 (communication from Master to Unisab III).

First step is to figure out the data/value which has to be written to the Unisab III. A legalvalue will be a number between Capacity setp1min and Capacity setp1max. Range of legalvalues will depend on the actual Unisab III configuration. To make sure a legal value is selec-ted, 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 doingthis in real, please make sure this value is inside the legal value range for your system, byreading setp1min and setp1max values.

The value written to Unisab III must be put at PWE 6 and PWE 7 as:

PWE 6 = 00000010PWE 7 = 11100110

To examine the data has been written to the Unisab III, try to read the Capacity Setp1 valueand compare the result with the written value (hopefully they are equal to each other).

4.5. Example 5: Writing timer for prelub.Wanted parameter is the timer for the prelubriation pump Prelub (communication from Mas-ter to Unisab III).* 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 III. A legalvalue will be a number between Prelub setMIN and Prelub setMAX. Range of legal values willdepend on the actual Unisab III configuration. To make sure a legal value is selected, the Pre-lub setMIN and Prelub setMAX values can be read.

Examples


In this example a value of 11001100111101 bin = 333D HEX (819 decimal) is chosen. Forpractical test purposes, please make sure this is inside the legal value range for your systemby reading setMIN and setMAX values.

The value written to Unisab III must be put at PWE 6 and PWE 7 as:

PWE 6 = 00110011PWE 7 = 00111101

5.4. Shutdowns and alarms with identification numbers for screw com-pressors

5.4.1 Shutdown and alarm textsIn the event of a shutdown or an alarm, Unisab will send a shutdown/alarm ID. The followinglists for screw and reciprocating compressors show the shutdown/alarm texts for all shut-down/alarm IDs. If no shutdown or alarm is active, Unisab will send the value 0. (Please notethat Unisab II sends the value 255, if no alarms are active.)On Unisab, several alarms can be active at the same time. In that case, the first two alarmswill be shown in alarm 1 and alarm 2.
