PLC System (S7-200)

We are one of the most prominent Manufacturers and Suppliers of a wide range of PLC System (S7-200). As system bus with up to 126 participants, Programming devices, SIMATIC HMI products and CPUs can be networked without a problem.
In the freely programmable mode up to 115.2 kbaud, with user-specific protocols such as ASCII (this supports interconnections with a modem, printer, barcode reader, PC, third party PLC and any other device). Up to 32 frequency converters can be controlled without additional hardware by using USS protocol instructions.
The integrated RS485 interfaces can be operated at data transmission rates from 1.2 to 187.5 kbaud. Our PLC System (S7-200) is highly praised for its high efficiency and durability. Our company also provides customization facility option to our clients.
Design and function
The built-in RS 485 interfaces can operate at data transmission rates up to 187.5 kbit/s. It has a system bus with a maximum of 126 stations. In this capacity, it is possible to network programming devices, HMI products and CPUs without a problem. The integrated PPI protocol is used for pure S7-200 networks supporting multiple masters from a single port. In a network consisting of other Siemens components (SIMATIC S7-300/400 and SIMATIC HMI, etc.), the S7-200 CPUs are integrated as MPI slaves.
Speedy Profibus Connection
All CPUs from 222 upwards can be run via the EM 277 communications module as a norm slave on a PROFIBUS DP network with a transmission rate of up to 12 Mbit/s. This open feature of the S7-200 to higher-level Profibus DP control levels ensures you can integrate individual machines into your production line. With the EM 277 expansion module, you can implement Profibus capability of individual machines equipped with PLC System (S7-200).
Powerful AS-Interface Connection
The CP 243-2 turns all CPUs from 222 upwards into powerful masters on the AS-Interface network. According to the new AS-Interface specification V 2.1, you can connect up to 62 stations, making even analog sensors easy to integrate. With AS-Interface, you can connect up to 248 DIs + 186 DOs in the maximum configuration. The maximum number of 62 stations can include up to 31 analog modules. The configuration of the slaves and reading/writing of data is supported by the handy AS-Interface Wizard.
Benefits

• Teleservice : The modem communication option is useful for avoiding expensive service calls. Two modems are all you need for remote use of the complete range of functions such as program transfer, status or control. The communications tools are integrated as a standard feature. External modems canbe used as local modems.
• Modem communications : The S7-200 CPUs can be accessed nearly anywhere in the world by modem via wired network or radio.
• Telecontrol : Messages and measured values can be easily called via modem as well as define new set points or commands. In this case, one base station S7-200 can control a nearly unlimited number of remote stations. The protocols for data transmission are freely selectable, e.g. for text messages directly to a cell phone, error messages to a fax machine or Modbus RTU.
