4.8 L_IOParPDO15 − Parameterisation function

4−19

LenzeIOSystem.lib EN 1.7

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.

ð Inputs (Variable type: VAR_INPUT)

FALSE ä TRUE Write request is executed

byNodeAdr Byte Device address: 1 − 63

bInitIOSystem BOOL

Initialise I/O system after parameterisation

TRUE · Value acceptance by reset node

· I/O system is re−initialised, state change to Operational

FALSE · No value acceptance

· I/O system is not initialised

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.
