It provides a 10/100 Mbit/s PROFINET interface on the first port and supports NTP for time synchronization across the network — critical when coordinating sequence-of-events logs or time-stamped alarms in a distributed control scheme. ## Configuration and protocol stack Configuration requires STEP 7 V5.4 SP1 or higher; for PROFINET CBA setups, SIMATIC iMap V3.0 SP1 or higher is needed. The module supports SNMP v1 for basic network management and includes an IP-based ACL to restrict access to the PROFINET interface — useful when the CP sits on a plant network shared with non-Siemens devices. It can act as an FTP client (up to 20 simultaneous connections) and as an email client (one session). The on-board flash file system provides 30 Mibyte of storage for firmware updates or data logs. ## Physical and environmental fit The module measures 25 mm wide, 290 mm high, and 210 mm deep, matching the standard S7-400 single-width form factor. Rated IP20, so it belongs in a ventilated enclosure — not a washdown or outdoor panel without additional protection. Power draw is 7.25 W from the 5 V backplane supply. The module does not include LLDP or ring redundancy, so if your network relies on Media Redundancy Protocol or topology discovery via LLDP, this CP won't support it.","metaTitle":"Siemens 6GK7443-1EX41-0XE0 CP 443-1 Advanced, NTP","metaDescription":"Siemens 6GK7443-1EX41-0XE0 CP 443-1 Advanced communication module for S7-400.
