Crossbow, Thanks Mate, I just saw the black box appears when you click on the initial values rectangle and brings up all of the components. A drop down arrow or + symbol to expand would have been clearer for a novice. Thanks Again

Thanks for your replay Crossbow. In the Variable table I have Name - DataType- Initial Value Modbus_Port - _sDevice_Port - Initial Value is Blank No option to expand Modbus_Port to see included tags in the structure How do you use the initial values to set all the components in the structure, will this only work if you are online?

Probably relates to this post because if you can't expand a structure and see all components to assign values rather than having to write structured text statements than that is a rediculous limitation of the software

Crossbow just asking for some clarification For Example if you Create a "Deviceport" structure and name it Modbus_Port for example. To set the Device type you have to write in a structured text entry Modbus_Port.DeviceType:=_DeviceNX_Unit Is there a way you can expand the Modbus_Port structure in a table/array format and see all components of the structure and assign them values other than writing structured text statements. How would you assign the DeviceType paramater to _DeviceNX_Unit using ladder logic? Any help would be greatly appreciated

Is there any way to expand the inbuilt Data structure components without having to write values to them in structured text. For Example - the sDevice_Port Data Type Can you expand this to show and edit the tags/data contained in this structure - eg. - DeviceType - NxUnit - Port No etc
