Connection 4.3 Connection examples Connection examples An external supply voltage is required to operate the device. Please consult the Technical data (Page 73) or the rating plate for the permissible supply voltage type and level. NOTICE Connection to the wrong supply voltage can cause irreparable damage to the device. Failure to heed this warning can result in damage to the device and the system.
Page 23
Connection 4.3 Connection examples Further connection example The SPP2000 is used as a gateway for a PAC2200/3200T. Using a switch, up to 8 of the PAC devices mentioned can be integrated in TIA. Further connection example The SPP2000 is integrated into the center of a PROFINET network with Conformance Class C. Up to the PAC devices mentioned, it uses PROFINET and Modbus TCP in parallel.
