Design
(continued)
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
Its 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 spring-
loaded 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)
