CANopen process data The data objects of the XN-1RS232 modules
cannot be mapped in default PDOs (PDOs1 to 4)
as they are not treated as I/O modules, in accor-
dance with DS401 (1st Device Profile in XN-GW-
CANopen).
PDO18 and PDO19 (RPDO18/19 + TPDO18/19)
are therefore prepared for use as RS232/4xx
PDOs in order to enable PDO communication with
XN-1RS232 modules with little configuration
required.
The first XN-1RS232 module generates in the
TPDO18 a mapping entry object 5601
hex
/Si 1 and
in RPDO18 a mapping entry object 5602
hex
/Si 1.
The second XN-1RS232 module generates in
TPDO19 a mapping entry object 5601
hex
Si 2 and
in RPDO19 a mapping entry object 5602
hex
/Si 2.
The PDOs must however only be enabled by a
valid COB-Id.
Other XN-1RS232 modules can be mapped by the
user to free PDOs or addressed with SDO commu-
nication.
TXBUF FLUSH 0 -1 The TXBUF FLUSH bit is used for clearing the
transmit buffer.
If STATRES = 1:
A request with TXBUF FLUSH = 1 will be
ignored.
If STATRES = 0:
TXBUF FLUSH = 1 will clear the receive buffer.
