General customer benefits

• Integrating the whole motor feeder into the process control by means of PROFIBUS DP, PROFINET, Modbus RTU or OPC UA significantly reduces the wiring outlay between the motor feeder and PLC.
• Decentralization of the automated processes by means of configurable control and monitoring functions in the feeder saves resources in the automation system and ensures full functionality and protection of the feeder even if the I&C or bus system fails
• The acquisition and monitoring of operating, service and diagnostics data in the feeder and process control system increases plant availability as well as maintenance and service-friendliness
• The high degree of modularity allows users to perfectly implement their plant-specific requirements for each motor feeder
• The SIMOCODE pro system offers functionally graded and space-saving solutions for each customer application
• The replacement of the control circuit hardware with integrated control functions decreases the number of hardware components and wiring required and in this way limits stock keeping costs and potential wiring errors
• The use of solid-state full motor protection permits better utilization of the motors and ensures long-term stability of the tripping characteristic and reliable tripping even after years of service

Multifunctional, solid-state full motor protection for rated motor currents up to 820 A

SIMOCODE pro offers comprehensive protection of the motor feeder by means of a combination of different, multi-step and delayable protection and monitoring functions:

• Inverse-time delayed solid-state overload protection (CLASS 5E to 40E)
• Thermistor motor protection
• Phase failure / unbalance protection
• Stall protection
• Monitoring of adjustable limit values for the motor current
• Voltage and power monitoring
• Monitoring of the power factor ? (motor idling/load shedding)
• Ground-fault monitoring
• Temperature monitoring, e. g. over PT100/PT1000
• Monitoring of operating hours, downtime and number of starts etc.

Recording of measuring curves

SIMOCODE pro can record measuring curves and therefore is able, for example, to present the progression of motor current during motor start-up.

Flexible motor control implemented with integrated control functions (instead of comprehensive hardware interlocks)

Many predefined motor control functions have already been integrated into SIMOCODE pro, including all necessary logic operations and interlocks:

• Overload relays
• Direct-on-line and reversing starters
• Wye/delta starters (also with direction reversal)
• Two speeds, motors with separate windings (pole-changing switch); also with direction reversal
• Two speeds, motors with separate Dahlander windings (also with direction reversal)
• Positioner actuation
• Solenoid valve actuation
• Actuation of a circuit breaker
• Soft starter actuation (also with direction reversal)

These control functions are predefined in SIMOCODE pro and can be freely assigned to the PROFIBUS/PROFINET inputs and outputs of the device (including the process image).

These predefined control functions can also be flexibly adapted to each customized configuration of a motor feeder by means of freely configurable logic modules (truth tables, counters, timers, edge evaluation, etc.) and with the aid of standard functions (power failure monitoring, emergency start, external faults, etc.), without additional auxiliary relays being necessary in the control circuit.

SIMOCODE pro makes a lot of additional hardware and wiring in the control circuit unnecessary which results in a high level of standardization of the motor feeder in terms of its design and circuit diagrams.

Detailed operational, service and diagnostics data

SIMOCODE pro makes different operational, service and diagnostics data available and helps to detect potential faults in time and to prevent them by means of preventative measures. In the event of a malfunction, a fault can be diagnosed, localized and rectified very quickly - there are no or very short downtimes.

Operating data

• Motor switching state derived from the current flow in the main circuit
• All phase currents
• All phase and phase-to-phase voltages
• Active power, apparent power and power factor
• Phase unbalance and phase sequence
• Ground-fault current
• Time to trip
• Motor temperature
• Remaining cooling time etc.

Service data

• Motor operating hours
• Motor stop times
• Number of motor starts
• Number of overload trips
• Interval for compulsory testing of the enabling circuits
• Energy consumed
• Internal comments stored in the device etc.

Diagnostics data

• Numerous detailed early warning and fault messages
• Internal device fault logging with time stamp
• Time stamping of freely selectable status, alarm or fault messages etc.

Easy operation and diagnostics

Operator panels

The operator panel is used to control the motor feeder and can replace all conventional pushbuttons and indicator lights to save space. It makes SIMOCODE pro or the feeder directly operable in the control cabinet. It features all the status LEDs available on the basic unit and externalizes the system interface for simple parameterization or diagnosis on a PC/PG.

Operator panels with display

As an alternative to the 3UF720 standard operator panel for SIMOCODE pro V, there is also an operator panel with display: the 3UF721 is thus able in addition to indicate current measured values, operational and diagnostics data or status information of the motor feeder at the control cabinet. The pushbuttons of the operator panel can be used to control the motor. Also, when SIMOCODE pro V PROFINET is used it is possible to set parameters such as rated motor current, limit values, etc. directly via the operator panel with display.

Communications

SIMOCODE pro has either an integrated PROFIBUS DP or Modbus RTU interface (SUB-D or terminal connection) or a PROFINET interface (2 x RJ45).

Failsafe disconnection through PROFIBUS or PROFINET with the PROFIsafe profile is also possible in conjunction with a failsafe controller (F-CPU) and the DM-F PROFIsafe failsafe digital module.

SIMOCODE pro for PROFIBUS

SIMOCODE pro for PROFIBUS supports for example:

• Cyclic services (DPV0) and acyclic services (DPV1)
• Extensive diagnostics and process alarms
• Time stamp with high timing precision (SIMATIC S7) for SIMOCODE pro V
• DPV1 communication after the Y-Link

SIMOCODE pro for PROFINET

SIMOCODE pro for PROFINET supports for example:

• Line and ring bus topology thanks to an integrated switch
• Media redundancy via MRP protocol
• Operating, service and diagnostics data via standard web browser
• OPC UA server for open communication with visualization and control system

• Interval function and measured values for energy management via PROFIenergy
• Module exchange without PC/memory module through proximity detection
• Extensive diagnostics and maintenance alarms

System redundancy with SIMOCODE pro for PROFINET

The unit supports the PROFINET IO system redundancy mechanisms, enabling it to be operated directly on high-availability systems such as SIMATIC S7-400 H. This means that SIMOCODE pro can also deliver decisive added value, even at the field level, in systems where the focus is on system availability and redundancy.

SIMOCODE pro for Modbus RTU

SIMOCODE pro for Modbus RTU supports, for example:

• Communication at 1200/2400/4800/9600/19200/57600 baud
• Access to freely parameterizable process image via Modbus RTU
• Access to all operating, service and diagnostics data via Modbus RTU

Notes on safety

In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens products and solutions only represent one component of such a concept.

Autonomous operation?

An essential feature of SIMOCODE pro is the autonomous execution of all protection and control functions, even when communication to the I&C system is interrupted. This means that even in the event of bus system or automation system failure, full functionality of the feeder is ensured or a specific behavior can be parameterized in case of such a fault, e.g. targeted shutdown of the feeder or execution of particular parameterized control mechanisms (such as reversal of the direction of rotation).

Advantages through energy efficiency

Overview of the energy management process

We offer you a unique portfolio for efficient energy management in the industry – a process that is used to optimize the energy requirements. We divide operational energy management into the three phases: identification, evaluation and implementation, and support you with suitable hardware and software solutions in each phase of the process.

The innovative SIRIUS industrial controls products can also make a major contribution to the energy efficiency of a plant (http://www.siemens.com/sirius/energysaving).

The SIMOCODE pro 3UF7 motor management system makes the following contribution to the energy efficiency of the plant as a whole:

• Energy consumption:
  Clear display of the energy consumption of a motor feeder or process element by means of the acquisition and transmission of all operating and consumption date, such as current, voltage, active and reactive power, energy consumption, motor temperature etc.
• Energy management:
  Evaluation of energy measured values (e. g. limit value monitoring) with exporting of local or central actions (= forwarding to higher-level)
• PROFIenergy:
  SIMOCODE pro V PROFINET supports the PROFIenergy functions. Reduced energy consumption thanks to automatic disconnection in the intervals and forwarding of the measured values for higher-level energy management systems.

Advantages from integrated energy management

As an integrated option for the TIA Portal, the SIMATIC Energy Suite couples energy management with automation efficiently, making energy consumption at your production facility transparent.

Thanks to the simplified configuration of energy-measuring components, e.g. SIMOCODE pro V, configuration effort is also clearly reduced.

Thanks to the end-to-end connection with higher-level energy management systems or cloud-based services, you can seamlessly expand the recorded energy data to create a cross-site energy management system.

The advantages at a glance:

• Automatic generation of energy management data
• Integration into TIA Portal and into automation
• Simple configuration
