It provides a 10/100/1000 Mbit/s RJ45 port and supports OPC UA server and client communication via a programmable user block per PLCopen, allowing a controller to serve or consume OPC UA data without an external gateway. ## Network and diagnostic features This module handles NTP (including secure NTP), SNMP v1 and v3, and OPC UA-compliant security mechanisms for encrypted data transmission. It includes web-based diagnostics with password protection, a log file for unauthorized access, and the ability to disable non-required services. The maximum number of monitored variables is 64000 items, with a queue size of 2 per variable and storage for 45000 bytes. ## Power and environmental ratings The module draws 1.3 A typical from the 5 V DC backplane bus, dissipating 6.5 W. It is rated IP20, operates at 0 to 60 °C, and survives storage and transport from -40 to +70 °C. Required engineering software: STEP 7 V5.5 SP4 HF10 or higher, or STEP 7 Professional V14 (TIA Portal) or higher.","metaTitle":"Siemens 6GK7443-1UX00-0XE0 CP 443-1 OPC UA, Active","metaDescription":"Active Siemens CP 443-1 OPC UA communications processor for S7-400, 1 RJ45 port, OPC UA client/server, NTP, SNMP, web diagnostics.
