Note!
Features and use of the L_IOParPDO15 FB.
·
Use the L_IOParPDO15 FB last in a sequencer consisting of several FBs for parameterisation.
By means of the L_IOParPDO15 FB, parameterisation of the I/O system is carried out.
·
For sending the NMT telegram, the controller has to be in the Operational CAN status,
therefore parameterise the controller as master. After the boot−up time has expired, the state
change from Pre−operational to Operational is automatically effected.
·
If several IO systems (stations) are parameterised with standard values via the
L_IOParPDO15 FB on the system bus, an identifier collision between the individual PDOs of
these stations can occur. Therefore check the identifiers used.
After changing to the Operational CAN status, the current process image of the I/O system is sent.

WORD Setting identifiers
Default values: input wiring = 0
RxPDO = receive identifiers from the I/O system
Identifiers can be optionally set by value selection.
If the input wiring is "0", the identifiers are composed as follows.
Note!
The basic identifiers are not settled in the pre−assigned area of the standard system
bus.
ID range: 384−831
By this, crossovers of the ID with the free CAN objects which the IO−lib is based on
are avoided.
