This is a series of 1:1 bitmaps downloaded directly from the AMLCD-240 touchscreen. All of the buttons on the touchscreen graphically appear to push down when touched, and their key values are entered onto the 18-character display. The touchscreen's back key and clear key also perform the expected functions. The ENTER key can link to another screen. Alphanumeric data entry has many uses - enter a name, an ID code, etc. All of this is quickly done without requiring intervention from the host PLC. Data can be read or written to PLC registers in any format that the Z-Card supports.
