I'm trying to determine which Codesys Control license I need, the Control Standard S has all the features I think I'll need, but the code size is limited to 3mb, I created a simple program with only 1 line of ladder logic and a simple visualization with a button and an indicator. When I generate code I get some messages, one indicates that the total allocated memory size for code and data is 2.1mb. Is this metric the correct size of the code? I question the size because it exceeds the allowable code...
you can configure the button actions in the hotkey tab in the visualization.
You get fewer tools when you create a new POU and choose ladder diagram instead of ladder logic diagram. Create a new POU and select ladder logic diagram and you should find the additional tools you are looking for in the toolbox.

The green icon with an ! next to the device is concerning. Is the data type correct for the input, you are using a byte input but the description says string. Is there anything useful in the status tab?
Does the device have a green icon next to it when the PLC is running? If not you have some kind of communication problem, wireshark may be picking up some data but the scanner may not be configured correctly to receive the data. Check the T>O and O>T bytes and make sure they match on both the scanner and adapter. I've had very little success loading a .eds file and having the configuration work without some manual configuration. If you have a green icon, have you enabled the device to always update...
Does the device have a green icon next to it when the PLC is running? If not you have some kind of communication problem, wireshark may be picking up some handshaking but the scanner isn't establishing a connection with the adapter. If you have a green icon, have you enabled the device to always update variables?
