Introduction
The tET/tPET and PETL-7060 series of devices are IP-based Ethernet I/O monitoring and control
modules that provide networking ability and a variety of digital I/O functions. The modules can be
remotely controlled through a 10/100 M Ethernet network using the Modbus TCP/UDP protocol.
Modbus has become a de facto standard communications, and is now the most commonly available
means of connecting industrial electronic devices. This makes the tET/tPET and PETL-7060series
perfect for integration with HMI, SCADA, PLC and other software systems.
