Handshake Flow Control
If data is exchanged via the serial interface, XPS-E supports the
following modes for the handshake:
– No Handshake
– Hardware Handshake. The receive data flow can be controlled at the
respective device by setting or re-setting the RTS-/CONTROL signal
(CTS/INDICATION=0 -> no sending). A corresponding example for
cabling can be found under chapter „S [
}
29]erial Interface“.
– Software Handshake. The receive data flow can be stopped by the
respective device by sending the control character XOFF (0x13). The
sending procedure will only be re-started if a XON character (0x11) is
received or a Timeout (XOFF-Timeout) for the receipt of the XON
character.
The interruption of the sending procedure or the XOFF timeout is
shown in the status byte of XPS-E (See Chapter„Communication
Status [
}
26]“ ) by means of the bit XOFF_CTS_FLAG.

Handshake/Modbus
The XOFF/Modbus timeout is calculated by means of VALUE *
100ms. This value is entered into Octet15 of the parametrization
data. If no software handshake or no Modbus Mode is selected, this
value is insignificant.
NOTICE
If the value 0 is given, the timeout is set to 10 seconds.
