SIMOTION  C with central and distributed I/O

The SIMOTION C Motion Control System is modular in design. It consists of a comprehensive and individually combinable hardware spectrum that uses components of the SIMATIC S7-300 series and Siemens drive technology.

Components and interfaces of the SIMOTION C Motion Controller:

• Analog drive interfaces (for C240)
  • For setpoint outputs to servo/vector drives
  • For setpoint outputs to the actuating valves of hydraulic drives
  • As analog outputs for optional use
• Pulse outputs for controlling stepper drives (for C240)
• Interfaces for incremental/absolute encoders for cyclic acquisition of an actual position value or as freely assignable up/down counter (for C240)
• Onboard I/O for high-speed I/O signals
• SIMOTION Micro Memory Card (MMC) for storing:
  • SIMOTION Kernel
  • User programs
  • User variables
• Integrated communications interfaces for linking:
  • Distributed I/Os
  • HMI systems
  • PG/PC
  • Other Motion Control and automation systems
  • Drives with digital setpoint interface
• Various status/error displays and mode selectors

The following components make up a SIMOTION C system:

• Motion Controller and Micro Memory Card (MMC)
• Other system components (depending on requirements) such as:
  • Load power supplies (PS) for connecting SIMOTION C to a power supply of 120 V/230 V AC
  • Central (not onboard) and distributed I/O components
  • Servo/vector drives with analog or digital setpoint interface or stepper drives

Mounting and connection technology

The simple design makes SIMOTION C flexible and easy to maintain:

• Rail mounting
  Simply attach the module to the standard mounting rail, swing it in and screw it tight.
• Integrated backplane bus
  The backplane bus is integrated in the Motion Controller. The Motion Controller is connected to the I/O modules via bus connectors which are plugged into the rear of the housing.
• The front connector coding prevents front connectors from being plugged into the wrong module type.
• Screw-type terminals or spring-loaded terminals for I/O modules
• TOP connect
  This connection method provides pre-assembled wiring with 1 to 3-wire connection systems with screw-type or springloaded terminals as an alternative to wiring directly on the I/O module.
• This system uses a defined mounting depth since all connections and connectors are recessed in the module and are protected and covered by doors on the front.
• No slot rules.

Expansion with central I/O modules

Up to 8 slots can be used to the right of the Motion Controller in the SIMOTION device for SIMATIC S7-300 I/O modules.

The IM 365 can be used to connect an expansion rack (two-tier design) to increase the number of slots available for I/O modules from 8 to 16 (including a maximum total of 4 analog modules). Multi-tier configuration with IM 360/IM 361 is not supported by SIMOTION C.

SIMOTION C can be mounted horizontally or vertically.

If additional I/O modules are required, the distributed SIMATIC ET 200 I/Os can be connected to a SIMOTION C via PROFIBUS DP or PROFINET IO (for C240 PN).

The number of pluggable I/O modules is also limited by the power required from the backplane bus. The power consumption of all modules which are connected to the same backplane bus must not exceed 1.2 A.

Expansion using distributed I/Os

The following can be used as distributed I/O components:

• PROFIBUS DP
  • All certified standard PROFIBUS slaves
    (DP-V0, DP-V1, DP-V2)
  • SIMATIC ET 200S/SP/M/MP/eco/pro/AL distributed I/O systems
  • SINAMICS S120 servo converters over PROFIBUS DP interface with PROFIdrive
  • Stepper drives over PROFIBUS DP interface with PROFIdrive
• PROFINET IO (C240 PN)
  • SIMATIC ET 200S/SP/M/MP/pro/eco PN/AL distributed I/O systems
  • SINAMICS S120 servo converters over PROFINET IO with IRT (PROFIdrive)

Interfaces

Operation, display and diagnostics

• 1 ? mode selector
• 1 ? LED strip for fault and status indicators

Onboard I/O

• 18 digital inputs
  (C240: of which 2 for local measuring inputs and 4 for global measuring inputs/zero marks,
  C240 PN: of which 4 for global measuring inputs)
• 8 digital outputs

Drive interfaces (C240)

• 1 ? setpoint output interface for up to 4 axes (optionally for analog, stepper or hydraulic drives; also usable as freely assignable analog outputs)
• 4 ? encoder inputs for incremental or absolute encoders (can also be used as freely assignable up/down counters)

Communication

• 1 ? interface for Industrial Ethernet
• 2 ? interfaces for PROFIBUS DP
  (of which one interface is for MPI)
• 1 ? interface (3 ports) for PROFINET IO (C240 PN)

Data backup

• 1 ? slot for SIMOTION Micro Memory Card (MMC)

Additional interfaces

• Power supply terminals

Data storage/data backup

The SIMOTION C Motion Controller has an integrated nonvolatile data memory for storing process variables.

The data is backed up on a SIMOTION Micro Memory Card (MMC).
