LEFT, RIGHT string can be substituted by use of OpconStrDelete. You can delete all characters from specified character to right and then content on the left remains and vice versa. But it is not much comfortable. 😡

In the meantime I found biggest disadvantage of option 2, which is you are not able to use it until you pack it in to the library and add it to references. This is not much comfortable during the development, because I need to continuously work with source code of object, base and peripheral in my project. I do not want to create library everytime I change something.

I am developing an object containing Object, Base and Peripheral as usual. In my Base there are some constants defined for usage in Object and also in Peripheral e.g.: MyBaseConstants {attribute 'qualified_only'} VAR_GLOBAL CONSTANT MY_DEVICE_PAR_COUNT : DINT := 5; END_VAR In some examples I found different approaches how to access this constant from object or peripheral: Use directly MyBaseConstants.MY_DEVICE_PAR_COUNT. Use namesapace OC_MyBase.MY_DEVICE_PAR_COUNT. Probably without attribute 'qualified only'. Use namesapace + global variable list OC_MyBase.MyBaseConstants.MY_DEVICE_PAR_COUNT. Too long for coding. What is the right way how to handle it?

My colleagues from the MES team and I are having a heated discussion 😀 about plcChangoverStarted content. They tell me that the type number that is being sent within plcChangoverStarted is the current one. What I've seen in other projects including Digital machine something is different and it works like this: Select type from File dialog and copy to Station.State.Data.New[1].TypeNo Send plcChangoverStarted event with this content. The type number I'm trying to change to is sent. Process changover. At the end send plcChangover with Station.State.Data.Cur[1].TypeNo. So my simple question is: Should the plcChangoverStarted contain the number of the current type (TypeNoCur), or the type I'm trying to change to (TypeNoNew)?

Thanks @Thorsten_Brach . I did not know about this possibility. What is your best practice? Put library and OSD file into separate folder in Std\Objects folder?
