Function keys
:
F7
OK
The "OK" key enters the data. If the module file does
not yet exist, it is set up when you confirm the entries.
F8
SELECT
If you press this key, a selection list is displayed with
possible entries for fields which cannot be edited freely.
Select values from the list with the cursor keys and
enter them in the field with the return key.
☞
The input or output area must always begin with an even byte
number and must always end with an odd byte number.
The fields remain empty if no input or output areas are required for the GP.
If you make errors in the entries, these are rejected by the COM. After you
press the OK key, an error message appears in the message line.
If you want to reserve areas for the cyclic interface (ZI), remember the
following when you are reserving areas:
➣
The area for the "global I/Os" (i.e. the area shared by all stations
involved) can be a maximum of 2048 bytes long (GPB0 to GPB2047).
➣
Per station, a maximum of 64 bytes can be used as output GPs. These
64 output bytes must be a continuous block in the P or O extended
input and output area.
➣
Per station, a maximum of 256 bytes can be used as input GPs. These
bytes can also only be located as a continuous block in the P or O
extended input and output area.
