"Frame" parameter group

In this parameter group, you can configure all parameters specific to the "Freeport". This
parameter group is only displayed when you have selected the "Freeport" value in the "MOBY
Mode" parameter.

Default value Description
Hard errors With this parameter, you set whether hardware
diagnostic messages will be reported.
•
•
RS232 / RS422 Selection of the interface type that the connect-
ed hardware (reader / optical readers) uses.
The default value depends on the interface
used.
Note: This parameter is only shown when
"MOBY Mode = Freeport" was selected.
Default value Description
8 Selection of the number of bits on which a
character is mapped.
None Parity selection
A sequence of data bits can be expanded by a
parity bit. With its value "0" or "1", the parity bit
is added to the sum of all bits (data bits and
parity bits) to form a defined status. This in-
creases data reliability.
•
•
•
1 Selection of the number of stop bits that indi-
cate the end of a character.
The stop bits are appended to every transferred
character during transmission.
None:
Apart from standard diagnostics, no other
alarms are generated.
Hard errors:
Critical hardware errors/faults are reported
by the S7 diagnostics.
None:
Data is sent without a parity bit.
Odd:
The parity bit is set so that the sum of the
data bits (including the parity bit) is odd
when the signal state is "1".
Even:
The parity bit is set so that the sum of the
data bits (including the parity bit) is even
when the signal state is "1".
