Overview of the PLC&PC Boiler Control Unit
The boiler control unit is composed of the PLC&PC control,it can be used for various boilers control system. The plc brand is Siemens and programmable, such as SIMATIC S7-200Smart, SIMATIC S7-300, SIMATIC S7-1200, SIMATIC S7-1500, SIMATIC S7-400. The PC brand is the DELL industrial computer or Advantech industrial computer. A programmable logic controller (PLC) is a digital computer used for the automation with ability to re-programmed the logic as per the requirements of users in industries. Relying on the experience of many technicians in the control of industrial boilers, the boiler plc control system is designed according to industrial standards for the special use environment of boilers, with high anti-interference performance. According to the special needs of customers, we can research and develop boiler plc control systems that meet industrial standards and meet customer requirements, so as to realize the intelligence of the control system.
The smart choice for automation: SIMATIC PLC controllers
Based on PLC or PC, SIMATIC controllers are powerful, compact, and modular, and can be installed in the control cabinet or directly on the machine. No matter what the application, there is always a suitable controller to choose from. According to the specific requirements of users, We equip Siemens SIMATIC control with the right solution for the boiler PLC control system. They enable consistent, powerful, and efficient automation engineering in a way typical of SIMATIC controllers in boiler PLC control systems.
We have many kinds of PLC control cabinets, such as wall-mounted cabinets, podium cabinets, MCC vertical cabinets, GGD vertical cabinets, and piano consoles. We generally configure different forms of control cabinets according to the number of boiler system detection points and the capacity of the boiler. Generally, we configure integrated PLC control cabinets including water pump control, and fan control below 6 ton/h steam boiler, and configure more than three control cabinets above 6 ton/h boilers, such as control cabinet fan, pump control cabinet, PLC control cabinet, sometimes, the power control cabinet also be optional.
PLC&PC Boiler Control Unit Working Priciple
PLC programming is widely used, powerful and easy to use, and has become one of the main devices of contemporary industrial automation. PLC and the host computer communicate with each other, the command issued by the host computer will be first given to the PLC, and then the PLC will be interpreted as the corresponding timing signal, directly control the corresponding PLC equipment. Sometimes, the PLC reads the status data of the device and converts it into a digital signal to feed back to the upper computer. The PLC+PC control system adopts a distributed control system. The PLC independently controls the field controlled equipment, and the upper computer manages and monitors each PLC. At the same time, it forms an independent operating system with the PLC, which will not affect the operation of each other.
PLC&PC Boiler Control Unit Technical Features
★ Industrial PC features
The chassis adopts steel structure, which has high anti-magnetic, dust-proof and impact-proof capabilities.
There is a dedicated backplane inside the chassis, and there are PCI and ISA slots on the backplane.
There is a special power supply in the chassis, and the power supply has strong anti-interference ability.
Ability to work continuously for a long time is required.
★ communication module
Support PROFIBUS master-slave communication, RS485 and RS232 communication modules provide connection and I/O for point-to-point serial communication connect to the master
★ Simple remote control application
The communication processor CP 1242-7 can be connected via a simple HUB (hub) or mobile phone, Network or Internet (Internet) to simultaneously monitor and control distributed.
★ Integrated PROFINET interface
The integrated PROFINET interface is used for programming, HMI communication and communication between PLCs.
★ Integrated process
high speed input
The controller has multiple high-speed counters, the main body supports a maximum of 100 kHz, and the signal board supports a maximum of 200 kHz for counting and measurement.
high speed output
The controller integrates high-speed pulse outputs for speed and position control of stepper motors or servo drives.
★ Memory
Provides up to 150 KB of shared working memory for user instructions and data. Also provides up to 4 MB of integrated load memory and 14 KB of retentive memory.
The SIMATIC memory card is optional and can be used as a programming card, transfer card and firmware update card through different settings. It allows easy transfer of programs to several CPUs. The card can also be used to store various files or update the firmware of the controller system.
★ Intelligent Device
Through simple configuration, the PLC controller can be configured as a Profnet IO intelligent device, and realize the distributed IO application of the master-slave architecture with the IO controller.
★ Expandable and flexible signal board design
One signal board can be connected to all CPUs, allowing you to tailor the CPU by adding digital or analog input/output channels to the controller without changing its size.
The Relationship Between PLC and PC in Boiler Control Unit
Different sensors and field devices are used to measure critical parameters such as water flow, steam flow rate, and water level. PC visuals are used to monitor the parameters, and PLC is used to control the operation. If the feed water flow rate, water level, and steam flow exceed the predefined value, then the entire setup will shut down and automatic check valves are opened to release the steam and pressure.
