MACROS
Single or multiple command sequences can be grouped together in macros and stored in the data flash
memory. You can then start them by using the Run macro commands. There are different types of
macro (compiler directive marked in
Normal macro
These are started by means of an ‘ESC MN xx’ command via the serial interface or from another
macro. A series of macros occurring one after the other can be called cyclically (movie, hourglass,
multi-page help text). These automatic macros continue to be processed until either a command is
received via the interface or a touch macro with a corresponding return code is activated.
Touch macro
Started when you touch/release a touch field (only in versions with a touch panel - TP) or issue an
‘ESC MT xx’ command.
Bit macro
will be started by a single line IN 1..8 (bit) will change or by command 'ESC MB xx'. Bit- Macro 1..8 are
good for falling edge and Bit Macro 9..16 are good for rising edge at input 1..8. It is possible to change
the assignment between Bitmacro and intput with command ‘ESC YD n1 n2 n3’ (see page 17).
Port macro
These are started when voltage (binary) is applied to IN 1..8 or by command 'ESC MP xx'.
Matrix macro
Matrix Macro 1..64: start when keypressed or by command 'ESC MX xx'. Matrix Macro 0: start after
release of key or by command. It is possible to change the assignment between keynumber and
Matrixmacro with command ‘ESC YX n1 n2 n3’ (see page 17).
Analogue macro
will start whenever voltage changes or limit exceeds or by command
'ESC MV xx'. See table at the right: It is possible to change the
assignment
Analoguemacronumber with command ‘ESC VM n1 n2’ (see page
15).
Process Makro
automatic start at fixed periode (0.1s up to 25s) or by command 'ESC
MC xx'. Up to 4 individual process may be defined by command 'ESC
MD ..'. These Process Makro will never be stopped by other
commands or activities.
Power-on-macro
Started after power-on. You can switch off the cursor and define an opening screen, for example.
Reset-macro
Started after an external reset (low level at pin 5).
Watchdog-macro
Started after a fault/error (e.g. failure).
Brown-out-macro
Started after a voltage drop under 3.0V (typ.).

Important: If a continuous loop is
programmed in a power-on, reset, watchdog
or brown-out macro, the display can no longer
be addressed. In this case, the execution of
the power-on macro must be suppressed.
You do this by wiring DPOM:
- PowerOff - connect pin 13 (DPOM) to GND
- PowerOn - open pin 13 (DPOM) again.
