I have ~20 analog signal (4-20mA or +/-10V) and about 50 digital TTL/24V DC signals I need to deliver between DAQ and PLCs and sensors and actuators (for elements such motion devices, vacuum elements, optical magnets etc.). In addition there is a safety circuit which should be mounted in every sub-system in my project.

The distance gap is ~50 meters.
What would be the best way to deliver data in my project?

Please consider baudrate and general data transfer time between the stations in the project.

For any question please make a note.

Thank you.

 

The better and safety way is using one of well-known field busses as EtherCAT for example. You must locate one or more nodes close to your sensors and choose PLC with field bus option as well.

 

Cable. Good old copper cable.
