An Ethernet/IP communication module is available for 8400 StateLine, HighLine and TopLine control cabinet devices, in addition to the Lenze 8400 motec and protec decentralized frequency inverters. This fieldbus interface features dual-port technology and an external 24V back-up supply. The Ethernet/IP module interfaces with the Lenze sequence control to expand device range and positioning procedures. Included in the 8400 TopLine drive, the sequencer allows up to 100 actions for automatic execution of positioning, which can be parameterized directly in the inverter. The 8400 TopLine can perform the same type of flexible positioning control that typically requires programming into a program logic controller. This includes waiting times, counters or branches, which can be influenced using external sensor technology or the inverter's internal signals. An integrated oscilloscope function helps commissioning, maintenance and troubleshooting. Signal scanning and recording within the drive can be performed in 1ms. The oscilloscope presents recorded signals with an adjustable time base from 5ms to 1s simultaneously for up to eight channels.
