This article offers those who master the classic InTouch R14, a step-by-step instruction on setting up communication with devices using the Modbus TCP protocol. I’ll try to explain those features of the settings that can put a novice developer in a difficult situation.
1. Licensing
The company Klinkmann supports developers of their products, issuing full, but temporary licenses, each of which operates a little less than a month. After the expiration of this period both the development system and runtime stop working. It is required to repeatedly request and update license files.
Usually three files are issued. All of these must be installed in the ArchestrA License Manager. It looks like this:
The absence of a license or an incorrectly installed license may be the cause of the lack of communication. After installing the license, it is desirable to reboot.
2. Download and install the integration package Server DA (DASMBTCP)
Detailed configuration instructions in the video:
3. As an emulator of the MODBUS TCP operation, I usually use the product from Modbus Tools (Modbus Pool & Modbus Slave)
Immediately configure the data exchange to make sure that everything we have is working with the Modbus TCP protocol and data is being exchanged.
Attention!!!
ID is set to 255. Otherwise it will not work. Where to change this value in driver properties – yet did not find. If your Slave device has a different ID, then the working connection will not be achieved.
We disable the Modbus Pool, we do not need the port to be busy at the beginning of the connection.
4. Configure the Server DA driver (DASMBTCP)
Pay attention to the port number (for example, indicated 503)!
Here we form a common list of tags that will exchange data with the PLC
- The preferred application for installing license(s) is ArchestrA License Manager. The application can be accessed via Start - All Programs - Wonderware - Common. If Archestra License Manager is not installed you can go to Start - All Programs - Control Panel - Programs and Features and right-click on InTouch and choose Uninstall/Change.
- Configure Wonderware MBTCP OI Server 1. Start - All Programs - Wonderware - ArchestrA License Server - ArchestrA License Manager 2. Click “No” in the Remote License Management Configuration popup 3. File - Install License File - browse to the ArchestrA.lic file (provided by Wonderware NorCal) 4. Close the License Manager 5.
- Select the “Embedded License” tab from the “Remote Management” dialog and copy the “Hardware Identifier” Visit our site to activate the license. You need your Wonderware credentials to log in to the site. You may also be asked the “License Serial Number” for the purchased license.
Help describes the signs that we can specify for correct data retrieval
5. Indication of parameters on video frame
We go in WindowMaker
Sentinel Agent and Manager Sentinel is a new feature included in System Platform 2017 Update 3. Sentinel constantly monitors the License Server to ensure that it is accessible. In the event that the connection to the License Server is lost, Sentinel can be configured to send a warning message so you can quickly fix any issues and ensure.
Create an Access Name that will be associated with our topic and server
Next, create the required number of tags associated with the Access Name
Next on the video frame create a dynamic text
Linking (linking) it with the tag we need
Archestra License Manager Missing
6. Run the system Online (Runtime)
If there is no error anywhere, values similar to those in the Modbus Slave
I experimented a bit with disabling the drivers manually. I found out that when communication is lost, the values remain on the screen without changing, without giving out any indication of an error. This is certainly not suitable for the work of the industry. I will look for how to implement otherwise, for example, the replacement of values by the signs of the lattice. I will supplement this article later, when I find a solution
