Description

This is the PRO-NET I/O controller. This board interfaces I/O boards to the PRO-NET network. An I/O controller can have up to 8 I/O boards connected to it. The I/O controller makes sure that the active measuring channels of the I/O boards that are connected to it are sampled and that the measured values are available for the measuring program. The PRO-NET master communicates with the I/O controllers through the PRO-NET network. If the master needs to read an input channel, it sends a request to the I/O controller. The I/O controller then supplies the measured value.

A maximum of 30 I/O controller boards can be connected to the PRO-NET network. Each I/O controller has up to 8 I/O boards connected to it. The I/O boards are connected to the I/O controller by means of a flat cable. The I/O controller itself has 4 measuring inputs, three of which can be used for smart temperature sensors, and all of them can be used to count pulses.
