Notes

In general, MPC4Mk2 + IOC4Mk2 modules support one processing block per input channel.

A maximum of 6 processing blocks can be configured per MPC4Mk2 module. A maximum of 3 multi-channel 

processing blocks can be configured per MPC4Mk2 module (two for dynamic input channels and one for 

auxiliary input channels). There are 2 to 10 processed outputs (data extractions) per processing function, 

depending on the function.

Alarm processing

Alarms : Alarm with configurable limits (severity levels), hysteresis and time 

delay per processed output (data extraction)

Time delay : Up to 60 s in steps of 100 ms

Hysteresis : Up to 20% of the alarm level (physical quantity)

Severity levels

• Machinery protection applications : Out of range+, Danger+, Alert+,

Normal,

Alert−, Danger−, Out of range−

• Basic condition monitoring 

applications

: Out of range+, Danger+, Alert+, Information+,

Normal,

Information−, Alert−, Danger−, Out of range−

Adaptive monitoring : Adaptive monitoring uses a control parameter provided by an 

auxiliary channel (typically speed) to multiply the configured alarm 

limits by multiple coefficients configured for different ranges of the 

control parameter.

Trip multiplier uses the DSI TM control signal to multiply the 

configured alarm limits by a single configurable coefficient.

optional inversion of individual inputs
