8 Position of the I/O modules in the terminal compartment
The terminal compartment contains up to four I/O modules, depending on the order code.
• Modules with four terminals can be in any of these slots.
• Modules with eight terminals can be in slot B or C.
The exact assignment of the modules to the slots is dependent on the device version. For a
detailed description refer to the Operating Instructions of the device in question.
The following restrictions apply when selecting the modules:
• The device may contain a maximum of four I/O modules.
• A maximum of two I/O modules with 8 terminals is possible.
