It delivers a 42 Mbit/s downlink and 5.76 Mbit/s uplink, enough for live SCADA data, remote firmware updates, and email alerts from the control cabinet. ## Protocols and security for remote access DNP3, IEC 60870-5, and OPC UA (via SCADA connection) are all handled on-module — no separate protocol converter needed between the S7-1200 and the control center. Encrypted data transmission and a stateful inspection firewall are built in, which matters when the module sits on a public cellular network and the plant security policy requires VPN-grade protection. It also runs an NTP client, so the PLC clock stays synchronized over the cell link — critical for sequence-of-event logging in power and water SCADA.","metaTitle":"Siemens 6GK7243-7SX30-0XE0 CP 1243-7 LTE US, LTE/GSM","metaDescription":"Siemens 6GK7243-7SX30-0XE0 CP 1243-7 LTE US communication module.
