GW EIP/ASCII...
28
PHOENIX CONTACT 3785_en_B
– Byte 1: Specifies the character that represents the first ETX byte. The GW EIP/ASCII...
looks for this character in the first ETX byte, if the length is one byte or two bytes.
Specify a value between 0 and FF in hexadecimal format.
– Byte 2: Specifies the character that represents the second ETX byte. The
GW EIP/ASCII... looks for this character in the second ETX byte, only if the length is two
bytes. Specify a value between 0 and FF in decimal format.
Strip RX STX/ETX Chars: When enabled, the STX and ETX characters are removed from
the received serial packets. Packets sent from the PLC by way of Ethernet to the serial ports
of the GW EIP/ASCII... are not checked for STX/ETX characters.
The GW EIP/ASCII... modules can also be configured to append characters to the
beginning or end of a serial packet.
Similar information is then entered under “Append Delimiters from PLC” in the same group:
Start transmission (STX): When enabled, GW EIP/ASCII... adds an STX (start of
transmission) byte sequence which is configured as one byte or two bytes when it
transmits a serial packet. If none is selected, the feature is disabled. If one byte is
selected, the GW EIP/ASCII... adds one byte the beginning of the packet. If two bytes is
selected, the GW EIP/ASCII... appends two bytes.
– Byte 1: Specifies the character that represents the first STX byte. The GW EIP/ASCII...
appends this byte if the length is one byte or two bytes. Specify a value between 0 and
FF in hexadecimal format.
– Byte 2: Specifies the character that represents the second STX byte. The
GW EIP/ASCII... adds this byte only if the length is two bytes. Specify a value between
0 and FF in decimal format.
End transmission (ETX): When enabled, the GW EIP/ASCII... adds an ETX (end of
transmission) byte sequence that is configured as one byte or two bytes marking the end
of the serial packet. The length indicates the number of ETX bytes; if none is selected, this
function is disabled. If one byte is selected, one ETX byte is appended to identify the end
of a serial packet. If two bytes is selected, two ETX bytes are appended to identify the end
of a serial packet.
– Byte 1: Specifies the character that represents the first ETX byte. The GW EIP/ASCII...
appends this byte if the length is one byte or two bytes. Specify a value between 0 and
FF in hexadecimal format.
– Byte 2: Specifies the character that represents the second ETX byte. The
GW EIP/ASCII... adds this byte only if the length is two bytes. Specify a value between
0 and FF in decimal format.
