4.9 L_IOParPDO610 − Parameterisation function

4−23

LenzeIOSystem.lib EN 1.7

Note!

Features and use of the L_IOParPDLO610 FB.

· Use the L_IOParPDO610 FB last in a sequencer consisting of several FBs for

parameterisation. By means of the L_IOParPDO610 FB, parameterisation of the I/O system is

carried out.

· Parameterise the controller as master.

After the boot−up time has expired, for the master the change from the Pre−operational to the

Operational status is effected automatically.

· For sending the NMT telegram, the controller has to be in the Operational CAN status.

· If several IO systems (stations) are parameterised with standard values via the

L_IOParPDO610 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.
