3 Project planning concept

The user is provided with suitable function blocks by the "LenzeIo1000Drvlib" library to

enable support of the decentralised I/O system through Lenze PLC products These function

blocks are implemented in an IEC 61131 program and serve both for parameterising the I/

O system and for process data processing. They provide digital and analog input and

output information of the I/O system. Configurations of the user via user codes are not

required.

3.1 Parameterisation and process data blocks

The "LenzeIo1000Drvlib" library contains two types of function blocks:

1. Parameterisation blocks

2. Process data blocks

Parameterisation blocks

Parameterisation blocks allow the modification of index information in the decentralised

I/O system and the transmission of specified data. These data are transmitted only once to

the I/O system during the initialisation phase..

 The parameterisation blocks for modules and monitoring functions are required for

individual parameter setting of analog modules, communication monitoring, etc.

 The parameterisation blocks communication settings (L_io1000ParPDO15

and

L_io1000ParPDO610

) are mandatory for data exchange between PLC and I/O system.

Process data blocks

Process data blocks are required for transmitting and receiving I/O data between PLC and

I/O system. The process data blocks L_io1000Data15

and L_io1000Data610 serve to

evaluate and process the current process data information of the inputs of the I/O system

in the PLC program. Information and data of the PLC control can be transmitted to the

process via the output modules of the I/O system.

 Note!

In case of parameterisation blocks with the same bus node address at the

byNodeAdr input, the bExecute inputs must not be set to TRUE at the same time.

The parameter setting of the modules and the communication settings of a bus

coupler have to be started successively.
