			<description> ok, I'll read the requirements and write documentation for the functions like in other OpenSCADA libraries. By comments I meant feedback from people who will use the library.  OK, I have included the library to the standard OpenSCADA libraries without your documenting as is, due to your mention &quot;License: GPLv2&quot;!  And I have tested only deserialize(), which works, but you must not to include temporary internal variables &quot;str&quot; and &quot;i&quot; to the function arguments!</description>

			<description> Hello Roman, is the opcua client library supporting methods with parameters (exposed by opcua server) ?  No and there is no need of such requesting here when the module page has no mention of such function.</description>

			<description> Hello everyone. I have implemented some functions for working with json. In the attachments there is a project with json.db. There is also a set of json files and a python script for checking the functions.  ...  I am not a professional programmer, but I tried to cover all the code with tests. I will gladly accept comments.  That is are you about &quot;comments&quot; or you want to include this in the standard OpenSCADA libraries?  If you are about the first, then I have no need in json right now for throw down all other and start to develop-debug-test your code. :)  If you are about the second with documenting and following support yourself, then say that directly, go to http://oscada.org/wiki/Special:MyLanguage/Documents/How_to/Create_module and satisfy the requirements!  PS: I am going to expand shortly the document by a part of the code creation for internal libraries with User API, but most the requirements there is actual.</description>

			<description>  2) I make simple server based on server-minimal.py with two variables: readable and writable.  when I go to &quot;Server nodes browser&quot; I see &quot;0x80070000:Variant type '0' is not supported.&quot; where 0x80070000 = OpcUa_BadDecodingError. and  OpenSCADA does not expect type 0. see picture = print screen of FreeOpcUa Client. As far as I understand, the type &quot;0&quot; is equal to &quot;Null&quot;. Object with problem is not my variable.Wireshark knows Null type too.  The external server just sends wrong data type, which OpenSCADA.OPC_UA considers as an error and normal servers never sends such data type!  And that is a real problem of that server since the OPC-UA specification have nothing about type 0 in the Table 1 of the OPC UA Part 6, that is the server sets flag &quot;0x01 False if the Value is Null&quot; of the value presence in the Encoding Mask field of the Table 15 of the same part and sets the missing value type 0, what is wrong!</description>

			<description>Hello! python has freeopcua library which consist client and server. And there is &quot;FreeOpcUa Client&quot; with gui. I have done some tests.   1) FreeOpcUa Client can read and write AGLKS without problem.  2) I make simple server based on server-minimal.py with two variables: readable and writable.  when I go to &quot;Server nodes browser&quot; I see &quot;0x80070000:Variant type '0' is not supported.&quot; where 0x80070000 = OpcUa_BadDecodingError. and  OpenSCADA does not expect type 0. see picture = print screen of FreeOpcUa Client. As far as I understand, the type &quot;0&quot; is equal to &quot;Null&quot;. Object with problem is not my variable.Wireshark knows Null type too. 3) OpenSCADA can read and write my  variables from &quot;server&quot;.</description>

			<description> I am new here,  I try to use OpenSCADA on Android TV-Box with Arduino-Uno modbus RTU and others USB2Serial RTU. I can't connect to /dev/tty* , I got error &quot;Error the serial port '/dev/bus/usb/001/003' open: Permission denied.&quot;  That is not about OpenSCADA development and OpenSCADA in whole!  That is about missing such devices' drivers-modules in the Linux kernel on Android and the device path &quot;/dev/bus/usb/001/003&quot; is wrong!  So, search such Android packages.</description>

			<title>Is there a plan to support the IEC61850?</title>

			<pubDate>Thu, 09 May 2019 20:01:25 +0300</pubDate>
			<description> I have a  uncertainty that the page of &quot;To do&quot; show the modules of DAQ and transport protocol for MMS and IEC 60850 will be created instead of IEC18650. It's meaning that  IEC61850 will not be developed temporarily.  This is meant, I will finish the IEC 60850 implementation into the present module &quot;MMS&quot;, as the top layer above MMS (IEC-9506), once I will need that, or somebody other will order these functions: - add for sessions support, optionally; - implement IEC-60850 and test with &quot;libiec60850&quot;.</description>

			<description> I installed the Centos 6 packages qt3-ODBC, unixODBC, etc..  I can see the odbc driver for Postgres and Mysql by ODBCAdministrator. Does anyone know whether there is any package odbc for dbf (xbase) files? I need to create a data source for accessing odbc dbf in Centos 6.  How that related to OpenSCADA at all?</description>

			<description>Hi  I have noticed that the IO parameters for DAQ templates of logical parameters, when stored in the MySQL database, are limited to a 200 character string. I have generated a logical parameter template that handles a list of parameters that are entered as text type IO. Everything works fine until the parameter is disabled and enabled again, since in the DB the list entered is truncated. (Attached images for better explanation)  I tried to solve it by changing the length of the field in the database, however the list is truncated to 200 characters.  If the field is saved &quot;manually&quot; with the list string, before enabling the parameter, the list is fully recovered when the parameter is enabled.  I have not been able to come up with a way to solve this. Is it possible that any improvement can be considered?  I hope I have expressed myself clearly enough. I really appreciate any comments. Best regards.  </description>

			<description> So according to what you tell me, is it possible to compare all types of variables with EVAL?  Yes, it is.   Could you say that the use of EVAL_INT, EVAL_REAL, EVAL_BOOL and EVAL_STR then is not necessary and can be considered simply as EVAL ?.  Yes, you can use EVAL for the most operations, but for the compatibility and for some direct assignments the EVAL_* of the direct types are continued to be useful.   Considering this, in practice it is very close to what I was proposing.  Sure but it must be obviously for you that I do this for self then I do it optimal for mine!</description>

			<description> As I commented on the use of NULL values in the archiving of data in MySQL databases, I think it would be very convenient to have the definition of the standard &quot;null&quot; value for all types of data (variables) and that this value can be Use as &quot;EVAL&quot;.  For me that works in the way and it's all fine!   Having a single error value defined as NULL, would facilitate the tasks of analyzing this condition, since for all variables, regardless of its type, the value indefinite or error would be null.  You can do it now also by: - comparing to the generic EVAL constant; - comparing any type of variable to any specific one constants EVAL_BOOL, EVAL_INT, EVAL_REAL, EVAL_STR for any type indifferently; - call a specific function isEVal() to the variable.   Moreover, I believe that when using NULL, the particular definition of an &quot;EVAL&quot; for each type of data would no longer be necessary.  For now I am not needed NULL here at all and EVAL is OK!</description>
