Area of the "Virtual keyboard" HMI → PLC static

Area of the virtual keyboard whose meaning/function can be freely defined.

If the ETC−MMI (PC user interface) is used, this is where the states of the

freely configurable PLC keys (soft keys) are stored bit by bit (see chapter "ETC−

MMI").

5.1.3 Data block 2

The communication between MMI and PLC takes place via this data block. An

image of the data block is provided in the Dual−Port−RAM.

Data word 0 ... 127 contains signals from the PLC to the MMI. Data word 128

... 191 contains signals from HMI to the PLC.

From data word 224, also all data of the machine constant MK_DW224_255,

which may be used application−specifically, is stored. This is the data for con-

figuring the machine.

The distribution of the data is left to the user and must be specifically de-

fined. The NC only provides for the data exchange.

The machine constants are copied into the data block when the system soft-

ware is loaded and if there is a permissible change of the machine constants.

The data is taken from the general machine constants for the configuration

of the machine. There is a reserved area for the configuration of the PLC (see

chapter "Machine constants").
