The MAXIFLEX R3c I/O Scanner is designed specifically for adding remote I/O to Maxiflex Systems. R3c differs from R2c in that it has a program port and serial port.

The R3c I/O Scanner is placed in the CPU slot of the Remote I/O Base.

This I/O Scanner automatically scans all I/O on its Base, and communicates this data with the Maxiflex M1593A Remote I/O Link Controller in the Master Base, making the remote I/O data available in the Master CPU's "Data Interchange Table (DIT)".

Up to 3 Remote I/O Bases, each with its own M1249A I/O Scanner can be connected to a single Master CPU Base, making a total of 1000 I/O accessible from the Master CPU.

The R3c CPU automatically identifies the presence of I/O modules and performs I/O scanning of these modules, making this data available to the Remote I/O Link Controller in the Master Base without the need for any programming.

The data link to the Maxiflex Remote I/O Link Controller operates on the Conet data highway, providing an event-driven token-passing ruggedised industrial network capable of running up to 10km.

This allows remote I/O Bases equipped with the Maxiflex M1249A I/O Scanner to be placed in the same panel as the Master Controller, or distributed across the site up to 10km away.
