Flags are one-bit operands. This means they can either have the value TRUE or
FALSE.

This chapter describes how to program the control elements of the JVM-104-
O15.
The HMI JVM-104-O15 has the following 8 input keys: [F1], [F2], [F3], [F4],
[POWER], [SCROLL], [ESC]and [HOME]. These input keys are user-program-
mable.
In register 361000 of the JVM-104-O15 a bit-coded map of the input keys is avail-
able. You can use this map for programming.
The following registers are available for programming the input keys:
Register Description
361000 Bit-coded map of the input keys
361000.0 [F1] key
Bit 0 = 1: [F1] key is pressed.
361000.1 [F2] key
Bit 1 = 1: [F2] key is pressed.
361000.2 [F3] key
Bit 2 = 1: [F3] key is pressed.
361000.3 [F4] key
Bit 3 = 1: [F4] key is pressed.
361000.4 [POWER] key
Bit 4 = 1: [POWER] key is pressed.
