Citect SCADA 2016 Tag Addressing

[KorhanGencer]

Greetings,

How should I refer the variables that come from Unity Pro as tags in Citect SCADA 2016?

For instance, I want to import some tags whose addresses are in a shape like %I0.2.0. I saw somewhere that %I and %IW can be represented as %M when MODBUS protocol as MODNET30 is being used as communication protocol. Additionally, I presume %M10001 would refer to %I0.0.0.

But how should I refer some variable addresses like %I0.2.X or %Q0.5.X?

Finally, I couldn't find any helpful topics in "Help" section found in Citect SCADA 2016. Any such luck for finding a helpful documentation where I can read the syntaxes of various industrial automation communication protocols for different software?

Thank you in advance,

Korhan

Usually ...


In the Modbus Data Model, Inputs (%I...?)are separate from Holding Registers (typically memory e.g. %M...). To read Inputs, use Modbus Function Code 4 (0x04) Read Input Registers; to read Holding Registers, use Modbus Function Code 3 (0x03) Read Holding Registers.

Usually.

Of course, how Unity Pro and Citect SCADA implement the Modbus Data Model could be a whole 'nother thing. See this link.


[Edit: I found this. I think that suggests you need to map (copy? move?) %I values to %M and/or %MW locations and then Modbus(30?) can access those mapped values.]


[Edit II: this link.]

Thank you so much for the information and documentation links. I'll be looking up to them and find a way to solve my problem.

Problem is that is there is no such thing as Citect SCADA 2016

You can found the installation guide for Citect SCADA 2016, here on Schneider Electric's website. So, there is a Citect SCADA 2016 version. Besides, my customer even has a particular license for it.

Do you have any suggestions for my problem?
