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.
