ABB Condition monitoring with AC500 PLC

Controller integrated or stand-alone condition

monitoring

The AC500 condition monitoring module FM502

is a natural part of the AC500 platform and

Automation Builder engineering suite, and can be

used in different condition monitoring concepts,

stand-alone or control integrated.

Due to the easy programming in PLC languages,

it is usable for a variety of use cases and is espe

cially suitable for plant, line and machine builders

as easy extension of their offering.

If controller integrated

• it enables at very reasonable cost

• the best prediction horizon as it can measure

online, when best measurement quality is given

without scheduling production interruptions

• while continuously protecting the application in

real time e.g. with the same or other sensor(s).

• Further inputs can be used as fast data logger

e.g. precisely documenting process quality.

Therefore it is not only able to continually check

the mechanical components but also gives fast

protection for spontaneous and large failures

even while measuring. The condition monitoring

mode creates a database internally or externally

for predictive maintenance. Automatic and user

assisted responses can be enabled to prevent

costly consequences including total failures.

As many as 16 vibration sensors + 2 encoder

counters can be connected.

The recorded condition monitoring data can be

stored in the CPU flash disk before communica

tion or directly analyzed. Higher level indicators

can be calculated and communicated to a local or

remote HMI or database system.

Predictive performance for your process or machines

• Easy and cost saving integration of condition

monitoring into the AC500 platform.

• Early detection of mechanical damages.

• Fast protection from spontaneous failures.

• Even complex C-code analytics can be used

locally for meaningful own performance

indicators.

• Leads to optimized planning of maintenance

instead of fixed, scheduled service and

spontaneous repair.

• No additional system or fixed software for

diagnostics and visualization needed.

• Easy storage of the data, locally (4GB) or in

remote servers and databases.

• Ideally suited also for retrofit of older equip

ment, as it can make use of mechanical reserves

of still valuable equipment.
