The 75 mm depth leaves clearance ahead of the backplane — plan the gland plate and bend radius for the Ethernet cable. IP20 rated for enclosed panel use. Power draw is 1.25 W. ## Telecontrol protocol stack and SCADA link The module speaks DNP3 and IEC 60870-5 out of the box, connecting to a SCADA host through Siemens Telecontrol Server Basic or Standard Telecontrol protocols. That means it talks directly to a control centre without a separate protocol gateway — one less device to fail on a hot mill line. It also runs NTP (secure NTP supported) to time-stamp events across the substation or line, and it handles encrypted data transmission between the remote site and the control centre. The 10/100 Mbit/s Ethernet interface is standard for plant-floor networks.","metaTitle":"Siemens 6GK7243-1BX30-0XE0 CP 1243-1, DNP3, NTP","metaDescription":"Siemens 6GK7243-1BX30-0XE0 CP 1243-1 telecontrol module for S7-1200.
