When is this flexible amount decided? Is this during runtime of the machine or during export/compile time of the project? For the latter there are maybe some more options with export template. For the first case, at runtime, I think the grid that you are using is probably the best way. That is, if your 8 parameters fit comfortably into 8 columns. You can link a variable to the Smart Control property VisibleRows (or something like that) to determine how many of your items will be visible. The grid itself can have scroll bars that become available automatically if the number of rows is too big. Another approach that I’ve seen and implemented myself is to have a single view with all the information about one item at a time. Then you supply next/previous buttons to navigate through all the items or maybe even a grid with just a single column from which the operator can select the item they want to look at. This method is most useful if your items contain either too much data to fit into columns on a grid control or if the data can’t be displayed in a gridcell, for example charts. ... View more

In BMG we implemented Modbus with a base object that provides IModbus as a channel. You can get such a channel by either using ModbusRtu which takes IOpconSerial and converts it into IModbus or you can use ModbusTcp which needs an IP address+port and creates IModbus from these parameters. Objects can then use IModbus as a channel parameter. If there is no existing objects then we have ModbusUniversalTemplate which makes programming a unit with Modbus interface quite easy. If you are a Bosch employee then you can contact me through Outlook/Teams (Marvin Werner) to get access to these objects and an introduction depending on your use case. If you are an external user that is working on a project for Bosch then you can try asking your Bosch contact person to contact me, if you think it's worth it. Alternatively use the solutions provided by Thorsten_Brach. That's how I was doing Modbus, too, before I created those objects. ... View more

Hello, I have been using Windows 11 for a few weeks now and haven't encountered any problems that stopped me from working. I am mostly using OES 4.11 and TwinCAT 4022 though and only sometimes CPS (5.5) and TwinCAT 4024. Yesterday I used my Win11 laptop as a TwinCAT runtime to test something locally. After the upgrade I had to run Win8SetTicks again but beyond that everything worked as before. I wouldn't refer to my experience as an in-depth test though. Just doing some station tryout and object development. ... View more

We have several convenience event handling methods, for example SetEventOnce which checks if an event was set before to make it very simple to avoid setting events multiple times, even without event handle variables. Or ClearEventByNumber which works similar to the old clear event function in Opcon. These functions should be available in Units, ExecUnits, ExecHandlers (and its derivatives), AddonEvHdls and AddonExecs. But I don't want to implement these methods 5 or more times in derived FBs, so I put them into a separate FB (called Plugin) that handles all of that. Now my derived FBs just instantiate the Plugin, register themselves with it and then they can use the Plugin to call these convenience methods. Since the plugin is a separate FB and not derived from OpconUnit or OpconEvHdl, it can only access their public methods. ... View more
