Introduction
The ERTEC 400 is intended for the implementation of PROFINET devices with RT and IRT functionality.
By virtue of its integrated ARM946 processor, integrated 4-port realtime Ethernet switch, and available options
for connecting external host processor systems to a selectable bus system (PCI or LBU), the ERTEC 400
meets all of the requirements for implementing PROFINET devices with integrated switch functionality.
