I am currently setting up a Magelis touchscreen and Twido PLC.
I have previously done this one an Idec PLC and screen but just used the PLC ladder logic and data registers with comparison functions so thias is a bit new to me.
I have written a script on the HMI to password protect a function, however I am currently using an internal variable in the panel and if the power is lost to the panel the user and password information is lost.
I know you can use memory words(%MW) to store ASCII values but from the Twidosuite help document you can only store two characters for every 16 bit word, which I am guessing would involve scripting to breakdown the user name and password.
Has anyone done this before?
