148 GX Configurator-PN

Default Device Addresses

For a new project GX Configurator-PN assigns default device addresses to the refresh buffers accor-

ding to the following schema

Buffer

Default Device Address

PROFINET Management (Outputs)

Y100

PROFINET Management (Inputs)

X100

Acyclic Buffer (Outputs)

Acyclic Buffer (Inputs)

D2100

Cyclic Output

D4542

Cyclic Input

D4542 + <cyclic output size>

The default device address of the cyclic input area is the first D-device behind the area occupied by

the cyclic outputs. It depends therefore on the cyclic output size of the network configuration.

Note: the default device address is only assigned in a new project and is not adjusted, when the cy-

lic output size changes due to changes in the network configuration.

Validation of IO Identifiers

Both functions 'IO Documentation' and 'Export PLC Code' validate the identifiers used in the IO confi-

guration. These identifiers include the names of DUT elements listed in the 'Items' tables as well as

the global variable names of the instances of these DUTs. The identifiers must conform to specificati-

on IEC 61131. Some of the restrictions checked are:

- global variable names must be unique within the PLC project

- identifiers must not exceed 32 characters in length

- identifiers must not contain 'hyphen' characters

- identifiers must not contain multiple consecutive underscores and must not end with one

If any of these restrictions are violated, GX Configurator-PN attempts to modify the identifiers in

question and displays warnings on the problems encountered in a separate dialog.
