Support Questions / Re: Reading DINT.bit returns bit position value, not true/false (v3.97c)

' And this is my revision because
'  2^31 can not be cast as int32
'  last bit is sign bit giving a negative value for dint.31

d(i) = Convert.ToString(((Convert.ToInt32(Responses(SequenceNumber).Values(ElementNumber)) And Convert.ToInt32(1 << BitNumber)) <> 0))

I have run the following tests:

Thanks,

Looks like it should work right (but some bit might give a negative value?); I will edit this reply after I run my test suite.

Same for INT, DINT.

For example: Read(IntegerTag.1) will return 0 or 2. I would expect 0 or 1.


AdvancedHMIDrivers.EthernetIPforCLXCom connectionAdvancedHMI;
connectionAdvancedHMI = new AdvancedHMIDrivers.EthernetIPforCLXCom();
... connecting and validating other read/write operations ...
connectionAdvancedHMI.Read("IntegerTag.1");

Many thanks, resolved

At least for the exception, it was AdvancedHMIControls.dll that was needed. So I hope it will work now, but I have no PLC until after the weekend.

I saw another thread in the bug section where it was reported that the dependencies had increased in the later versions... I can understand why as the focus of the project is a HMI platform. But this would be a cleaner and more configurable platform if the graphical interfaces which I believe are in the "Control" was separated from the IO-part contained in "Drivers".

And I saw that v 1.70 also had the GetTagInfo(), so I could have settled for that to solve my original question : )

The dll's needed are
AdvancedHMIControls  (for versions > 1.7 up to and including v 1.97, which was the most recent)
AdvancedHMIDrivers
MfgControl.AdvancedHMI.Drivers

Ok, thanks again.

The error is there for all above v3.70 as you said. But I do not understand why.

I do not have any namespace issues reported by VS and everything compiles ok. Although using my old project, I wrote a new test class and the only thing I did was to create an instance of it, but modify the IP-property throws exception.

My application does not contain any UI, only read/write operations. It only uses the drivers mentioned; not the ones for control. Could there be some build issues (version/architecture) changes made in 3.80 that are hidden from VS because the direct calls to some DLL?

Thanks,

I did not have that method in my version, and have upgrade to using BetaV397c, more specifically the drivers:
AdvancedHMIDrivers.dll
MfgControl.AdvancedHMI.Drivers.dll

I built the AdvancedHMI solution on my PC and has referenced the compiled drivers.

EDIT: This version seems to have affected my whole project. I cannot connect anymore.
AdvancedHMIDrivers.EthernetIPforCLXCom connection = new AdvancedHMIDrivers.EthernetIPforCLXCom();
connection.IPAddress = "...";

NullReferenceException on Line 115 in EthernetIPforCLXCom.vb.
And a MsgBox saying: Incomplete solution.

Support Questions / Bit write with Logix ethernet / How to get data type from Read()

Hi all,

To make this work I have the following solution, that unfortunately does not work for INT.bit, only for DINT.bit. Is there a way to get the datatype from the driver read response? Then I can do it right.

The CIP message should as I understand it (1756-PM020A-EN-P, page 12) report the datatype, so it would be nice to be able to get that one too when calling AdvancedHMIDrivers.EthernetIPforCLXCom.Read().

This is my current solution, not usable for INT - only DINT.
1. Detect if the tag has a dot suffix - Tag.x
2. Read Tag as DINT and bit mask to desired value
3. Write tag as DINT
