Slots For Expansion Modules - Siemens SENTRON PAC4200 Manual

MDI-X auto crossover describes the ability of the interface to autonomously detect the send
and receive lines of the connected device and adjust to them. This prevents malfunctions
resulting from mismatching send and receive wires. Both crossed and uncrossed cables can
be used.

expansion modules.
Please consult the current catalogs to find out which modules are available for
SENTRON PAC4200.
One expansion module can be operated alone on the device or two expansion modules
simultaneously.
Two communication modules cannot be simultaneously operated, e.g. SENTRON
PAC PROFIBUS DP and SENTRON PAC RS485.

Avoid contamination of the contact areas below the labels "MOD1" and "MOD2", since
otherwise the expansion modules cannot be connected or can even be damaged. Insertion
of metal pins or wires into the contact openings can result in device failure.
