MR Series controllers

Melody controllers are designed for maximum

computing power and modular scalability.

Each controller can handle up to 2.000 analog

and/or digital I/O points from the local I/O, and

additionally 6.000 analog and/or digital I/O

points connected via PROFIBUS DP. In addition

to the standard tasks such as signal processing,

loop and logic control, the MR Series controller

also performs complex computations such as

sequential, batch and advanced controls.

Diagnostic routines periodically check the

hardware and firmware integrity. 

Each node on the control network operates

autonomously. Acting as its own communication

manager, the system requires no traffic directors.

The controller’s associated I/O modules are

connected using the high-speed redundant serial

field network or PROFIBUS DP (DPV1 as well as DPV2).
