PROFIBUS-DPV1

FOUNDATION Fieldbus HSE

MODBUS (Master/slave, RTU or ASCII)

IEC 60870-5-101, IEC 60870-5-104

CAN bus for Freelance rack-mounted I/O


The fieldbus and device connection can be configured and parameterized entirely through the Freelance engineer station software. No additional external software tools are required for the configuration process.
