The Siemens 6GK7443-5DX02-0XE0 is a SIMATIC NET CP 443-5 Extended communications processor that connects a SIMATIC S7-400 to PROFIBUS DP networks. It mounts as a compact single-width module in the S7-400 rack, with dimensions of 210 mm depth, 25 mm width, and 290 mm height.
Integration notes
The module draws power from the S7-400 backplane at 5 V DC. The only PROFIBUS interface is a 9-pin Sub-D socket (RS485); there is no Industrial Ethernet port on this unit. Configuration requires STEP 7 V5.1 or higher with the NCM S7 for PROFIBUS option package. Operating temperature range is 0 to 60 °C; storage and transport tolerate -40 to +70 °C. The enclosure is rated IP20.
