I am looking forward also to your project to study them by myself.
I am thankful and hope you can help me very soon.
I try to explain my problem. First of all I am quiet new in this automation and communication area, but I try my best because I like the topic so far.
I already started my automation project with the OSS OpenPLC from Thiago Rodrigues Alves and because he recommends and praises and refers to ScadaBR so much I want to try it too!
But I have no Idea where to start.
I need detailed information.
Why I do what?
What are the first steps to do?
What do I want to do:
In the end I want to have a Scada System which is able to communicate with ModbusTCP/IP with the PLC I already have and that I can set alarms (for specific (1) number/ or (2) duration of pushing a button during a specific time) and I also want a nice view (i.e.: (2) a picture where the user can see how long a button is pushed and if it is more then 10 seconds a red lamp will shine/alarm starts)
How I started already:
If I read it correctly I should start with creating a data source, right?
I already tryed this with help of Thiago Rodrigues Alves post:
https://openplc.discussion.community/post/big-update-with-new-cool-features-8173271?pid=1292945147 --> but there was also no explanation why I do all this.
First I choosed the DataSource: Modbus IP (I guess because I want my devices to talk ModbusTCP/IP this makes totally sence)
And now all my questions starts first:
Name: How important is this name, what is a smart way to call it
Export ID: For what do I need this? Why there is already a name written in it?
Update periode: okay I guess it is kind of the loop time
Timeout: Timeout for what?
Retries: What does the entry "2" means? What is the difference of Retries and Update periode?
Contingous batches only: When I need this?
Create slave monitor points: And when I need this?
Event alarm levels: When I should change something of this
Data source exeption:
Data read exeption:
Point write exeptions:
Modbus read data:
Slave ID: Should I use the slave ID from my ESP8266 Devices?
Register range: ?
Offset (0-based): ?
Number of regisers: ?
Here are my entries and the error messages:
