hi Wormus,

you can see the information about the Status in TIA-help.

TIA-help for Modbus Master-block

16#8182

the module does not support this parity-setting

select a suitable value for "Parity" at the PARITY parameter.

the following are valid:

-None (1)

-Even (2)

-Odd (3)

-Mark (4)

-Space (5)

-Any (6)

 hope this helps,
