Designed for a single RJ45 port (AUI alternative), it handles up to 64 active connections in multi-protocol mode and requires NCM S7 for Industrial Ethernet for configuration (bundled with STEP 7 V5.x). ## Time synchronization and diagnostics NTP client capability is present, enabling the CP to synchronise the S7-400 clock with a plant-wide time source—critical for audit-trail timestamps in regulated environments. Web-based diagnostics provide a browser-accessible fault summary without dedicated software, supporting remote troubleshooting. Note that LLDP is not supported, so neighbouring device discovery must rely on other protocols. ## Physical integration and power The module occupies a single slot in the S7-400 rack, measuring 25 mm wide, 290 mm high, and 210 mm deep (–). IP20 protection suits cabinet installation with no conformal coating. Power is drawn from the backplane at 5 V DC (–); no separate supply wiring required. Ambient operating range is 0 to 60 °C.","metaTitle":"Siemens 6GK7443-1GX11-0XE0 CP, NTP, Web Diagnostics","metaDescription":"Siemens 6GK7443-1GX11-0XE0 CP for S7-400, single-width, 10/100 Mbit/s, NTP client, web-based diagnostics, 64 connections, current production.

They are important components in a holistic industrial security concept. With this in mind, Siemens’ products and solutions undergo continuous development. Siemens recommends strongly that you regularly check for product updates. For the secure operation of Siemens products and solutions, it is necessary to take suitable preventive action(e.g. cell protection concept) and integrate each component into a holistic, state-of-the-art industrial security concept. Third-party products that may be in use should also be considered. For more information about industrial security, visit http://www.siemens.com/industrialsecurity. To stay informed about product updates as they occur, sign up for a product-specific newsletter. For more information, visit http://support.automation.siemens.com.
