Вопрос: Добрый день. Очередной раз обращаюсь за помощью по чиллеру BREF2812A. Мы с заказчиком перепробовали кучу файлов но так и не нашли нормального файла.
Было решено привязать чиллер по Modbus но в том что фале, который был на сайте нет всех данных что есть в SNMP-файле. То есть и файл SNMP и Modbus в каждом из них есть то, что нам надо но соединить эти данные ни как. Поэтому прошу предоставить рабочий файл для DCE по протоколу Modbus. Данные, которые мы хотим видеть в приложенном формате PDF. Ах да напомню что данный чиллер не является сторонним продуктом, а принадлежит компании Schneider Electric. Прошу оказывать содействие в наладке данного файла. Готов ответить на все вопросы, если что нужно выслать дополнительно, говорите вышлем.

Hi amelnikov,
Please tell us the versions of all SNMP and Modbus DDF-files with which you worked, and which do not suit for you chiller BREF2812A.
Further, tell us, please, did you try these two DDF-files, which can be downloaded on request from Device Support:
If not, then try: within one working day for you will be sent links to download DDF-files.
In addition, I highly recommend reading Roman Osadchyi answer in topic . Registration on this resource requires one working day, but it is free.
On the resource you will find a lot of useful information, and in particular, the latest SNMP and Modbus DDF-files, pCOWeb webpages, SNMP MIBs and instructions for Big Chiller - BRE-C-F. So on this resource you can download the following DDF-files:
uniflair_bref_TCPIP_Modbus_chiller - v.5
uniflair_bref_TCPIP_Modbus_chiller_imperial - v.5
uniflair_bref_SNMP_chiller - v.5
uniflair_bref_SNMP_chiller_imperial - v.5
uniflair_bref_SNMP_chiller_multiple - v.5
uniflair_bref_SNMP_chiller_multiple_imperial - v.5
I hope this information will help you in solving the problem. I can not help in more detail unfortunately, since I do not know all the details of the installation of your chiller.
If you have any questions, please ask.
With respect.

Hi amelnikov,
Addition to my answer: at the specified link Device Support you can send two absolutely identical SNMP DDF-file:
uniflair_bref_SNMP_chiller - v.2
As you can see from the version of this DDF-file, it is a little outdated. But even it is also recommended to try it.
With respect.

По протоколу SNMP и Modbus очень мало значений. Нет нужных значений. В файле PDF ( https://cloud.mail.ru/public/oWJP/ebzTSwn96) есть все нам нужные значения.
Как можно с PDF транслировать все данные в Modbus?

В данной стать нет решения нашей проблемы. У нас работает связь исправно. Данная статья нам не подходит.
In addition, I highly recommend reading Roman Osadchyi answer in topic PCOWEB - DCE - Uniflair TDAV1622A. Registration on this resource requires one working day, but it is free.

Научите меня вручную собирать Modbus файлы.

http://webcard-it.schneider-electric.com - Да я зарегистрировался на данном ресурсе, скачал все что возможно. Попробовал все файлы подходящие к BREF, безрезультатно.
На фото, датчики с SNMP v2- Это самый удачный вариант файла. В версии v3 и v5, 50% датчиков могут показывать отрицательные значения. Или вообще писать не подключен.
Я и раньше сталкивался с охлаждением. У меня есть опыт работы Uniflair. Вы смотрите не в ту сторону, я говорю что необходимо сделать нормальный Modbus файл. Так как SNMP перекликается с другими устройствами охлаждения.

Hi amelnikov,
Я и раньше сталкивался с охлаждением. У меня есть опыт работы Uniflair. Вы смотрите не в ту сторону, я говорю что необходимо сделать нормальный Modbus файл. Так как SNMP перекликается с другими устройствами охлаждения.
In order to avoid such problems with SNMP with many devices, it is necessary to fulfill the requirement from file Chillers_DDF.zip\Chillers_DDF\SNMP_WITH_OTHER_CHILLERS_TYPES_OR_CRAC_SERIES\BRE\BRE_pCOWeb_guide.txt where it says:
SNMP PROTOCOL - Multi Family approach
1. Access via FTP (Username = root Password = froot) to the pCOWeb
2. Copy the file snmpoid in this link /usr/local/root/flash/etc/sysconfig
3. Reboot pCOWeb
********************************************************************OR do use the simple procedure as reported in the"Important suggestions area" ===> SNMP OID CHANGE
This is important and if you do this, it will be much easier to correctly discovering of SNMP chillers from a DCE-server.
I hope this helps you.
I was glad to answer your questions.

Hi amelnikov,
Based on your last question about the problem, I strongly recommend that you create a Device Support Request on page Device Support for your chiller type and specifically for Modbus. Therefore, give there a maximum of information that you consider important with detailed explanations.
I repeat, on the above page, this type of chiller is only supported by SNMP. If you want to discuss or get help on SNMP DDF-files for your chiller, I highly recommend send e-mails to the address specified in the screenshot from resource http://webcard-it.schneider-electric.com:
With respect.
