Application:
The SIMATIC S7-200 is the micro PLC for open-loop control and closed-loop control tasks in machine and plant construction. It combines the greatest possible automation effect with the lowest costs.
SIMATIC S7-200 applications range from replacing relays and contactors to handling complex automation tasks in standalone mode, in networks and within distributed configurations.
To save costs, the S7-200 is increasingly being employed in areas that previously required special electronics.
Applications include:
Baling presses
Plaster and cement mixers
Ventilation plants
Centralized/flange lubricating systems
Woodworking machinery
Gate controls
Hydraulic lifts
Conveyor systems
Food and beverage industry
Laboratories
Modem applications (remote monitoring and maintenance)
Electrical installations
Design
The SIMATIC S7-200 family consists of the following modules:
5 basic devices with graded performances in different versions.
15 different digital and analog expansion modules.
2 communications processors for connection to PROFIBUS and AS Interface.
Mechanical features
Rugged, compact plastic housing.
Easily accessible connection and control elements, protected by front flaps.
CPU 224 and higher: Removable connection terminals, also for digital expansion modules.
Equipment features
International standards:
SIMATIC S7-200 complies with the standards according to VDE, UL, CSA and FM (Class I, Category 2; Danger zone groups A, B, C and D, T4A). The quality management system used during production is certified according to ISO 9001.
Communication
The SIMATIC S7-200 provides various possibilities for communication:
Communication interface:
Can be operated in PPI slave, MPI slave and in the freely-programmable interface mode.
Connection to AS-Interface:
As master via CP 242-2 communications processor.
Connection to PROFIBUS DP as slave:
Via PROFIBUS-EM 277.
PPI network
PPI is the communication system integrated in every S7-200 CPU. Connections for programming, operation or monitoring can be established over a common two-wire cable. The CPUs can communicate simultaneously with several CPUs, TDs or OPs. Data transmission rates 9.6, 19.2 and 187.5 Kbit/s.
The following can be connected:
Programming devices: Field PG, Power PG.
PCs (AT-compatible), via PC/PPI cable.
TD 200 Text Display, TP070 Touch Panel; SIMATIC Operator Panels.
SIMATIC S7-200:
Max. 31 S7-200 PLCs on a common data line to a PG, PC, TD 200 or OP. Direct data exchange between S7-200 PLCs (in each case as master) and NETR and NETW
