SIMOTION  C with central and distributed I/O

The SIMOTION C motion control system is designed with modular principles in mind. 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 design 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 spring-loaded terminal as an alternative to wiring directly on the I/O module.
• This system uses a standard 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 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. 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/O 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

Distributed I/Os can be assembled with intelligent I/O system components:

• SIMATIC ET 200S
• SIMATIC ET 200SP
• SIMATIC ET 200M
• SIMATIC ET 200MP
• SIMATIC ET 200pro
• SIMATIC ET 200eco
• SIMATIC ET 200eco PN (for C240 PN)
