Storage and transport can handle -40 to +70 °C. ## What you need to know before fitting it NTP? No — this module doesn't handle network time protocol. Time sync comes from the SCADA master via DNP3 or from the PLC's CPU. Firmware update possible remotely. Programming requires STEP 7 Basic or Professional. One RJ45 port at 10/100 Mbit/s. Backplane current budget: max 3 modules per CPU. Power supply draw is zero — powered entirely from the backplane.","metaTitle":"Siemens 6GK7243-1JX30-0XE0 CP 1243-1 DNP3","metaDescription":"DNP3 SCADA module for S7-1200.
