General customer benefits

• Integrating the whole motor feeder into the process control by means of PROFIBUS DP, PROFINET/OPC UA, Modbus RTU or EtherNet/IP significantly reduces the wiring between the motor feeder and the 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 electronic 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.
• Thanks to the precision of the current, voltage, power and energy measurements (especially those acquired by the 2nd-generation current/voltage measuring modules), costs can be internally allocated with a high degree of accuracy.
• By virtue of its wide frequency range (20 to 400 Hz), SIMOCODE can be used in combination with the 2nd-generation current/voltage measuring modules in a a wide range of motor applications.

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 П† (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 inputs and outputs of the device (including the PROFIBUS/PROFINET 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
• Frequency
• 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. Furthermore, it is possible to set parameters such as rated motor current, limit values, etc. directly via the operator panel with display (with SIMOCODE pro V PROFIBUS as of E15, SIMOCODE pro V Modbus RTU as of E03 and with all SIMOCODE pro V PROFINET and EtherNet/IP).

Communications

SIMOCODE pro has either an integrated PROFIBUS DP or Modbus RTU interface (SUB-D or terminal connection) or a PROFINET or EtherNet/IP 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 PROFIBUS supports, for example:

• Cyclic services (DPV0) and acyclic services (DPV1)

System redundancy with SIMOCODE pro 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 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 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
