205PLC Code for PROFINET Controller

Call FB 'IO_Device_Info'

The input 'ID' contains the IO-device number '1'. By setting M44 the alarm request is started. M45 in-

dicates that the requested data has been written to the global variable 'Device_Info_1'.

8.2 Global Variables

The exported PLC code contains several global variables for addressing the interface of the

PROFINET Controller. There are two types of variables:

1. project-independent variables with fixed names and structures related to the PROFINET manage-

ment and acyclic communication buffers in the PROFINET Controller

2. project-specific variables with editable names and structures related to the cyclic communication

data of I/O devices and their modules

The following table lists the global variables and the respective 'Data Unit Types' (DUTs), of which the

structure is independent of the IO devices in the network.
