T100MD2424 plus one EXP1616R would means that MD-HMI I/Os starts from 41 to 56. This is not included in the sample files.
The changes to be made are very simple. You can start off from the supplied file "HMI25to40.PC5". Shift the I/O table to move the keys to 41 to 56 (right click and select shift down). Then the only changes you need to make is in function 255
DM[3900] = INPUT[3] ' Get data from input #33-48
DM[3901] = INPUT[4] ' Get data from input #49-64
The rest of the programs are the same! Give it a try. That will show you how you can modify the program if you have other combinations of PLC + EXPs.
Below is the full text of the function 255 if it helps. If you still have a problem, email to support@tri-plc.com and we can email you the file we modified.
' This function handles the keypad scanning and make sure that a key must be
' pressed and released before the next key can accepted. It reserves the use
' of the Z$ string variable so you should avoid modifying Z$ in other part of
' the program.
