Parameter Description Setting range Default Menu path
Physical Settings Digit 1: Number of bits. Digit 2: E=even parity, O=odd
parity, N=no parity. Digit 3: Number of stop bits. More
information on the parity: It is possible that the last data
bit is followed by a parity bit which is used for recognition
of communication errors. The parity bit ensures that with
even parity ("EVEN") always an even number of bits with
valence "1" or with odd parity ("ODD") an odd number of
"1" valence bits are transmitted. But it is also possible to
transmit no parity bits (here the setting is "Parity =
None"). More information on the stop-bits: The end of a
data byte is terminated by the stop-bits.

AllowGap If this parameter is active (True), the User can request a
set of modbus register without getting an exception,
because of invalid address in the requested array. The
invalid addresses have a special value 0xFAFA, but the
User is responsible for ignoring invalid addresses.
Attention: This special value can be valid, if address is
valid. Inactive,
