35.3 Inserting I/O devices in the hardware configurator
► Select the Profinet device in the hardware catalogue and move it to the Profinet
network using drag & drop�
The devices all have modules with the same structure in slot zero� This is where
the communication submodules are located�
35.4 IO-Link devices
The IO-Link devices have a module in slot 1 in which nine slots are configured�
Subslot 1 contains the status/control module which has 4 bytes of input data and
4 bytes of output data� These are shown in the IOLM_Status table (input) and
IOLM_Control table (output)�
