BMS Building Management System

Buildings are subjected to changeable and at times extreme weather conditions.

Providing owners with the satisfactory data that enables them to control and monitor their building, whilst at the same time providing a suitable working environment for those within, becomes a difficult requirement to fulfill.

Building Management Systems monitor and control services such as heating, ventilation and air-conditioning, ensuring they operate at maximum levels of efficiency and economy. This is achieved by maintaining the optimum balance between conditions, energy usage and operating requirements.

The key components are

Controllers
Microcomputer controllers receive signals from field devices and according to their programmed operating parameters, take action to control plant equipment.

Supervisors
Supervisors view or amend the system data as well as providing a wide range of energy analysis and maintenance functions.

Networks
Networks allow devices to communicate across a physical distance either locally, across a wide area network, or remotely by using standard browser technology. This means information can be accessed from anywhere in the world, ensuring total building continuity.

Field Devices 
Field devices send or receive data directly to controllers for either local or remote control & monitoring. If you don’t measure or monitor an area or item you can not control it.

High speed Yokogawa PLC and DCS Technology

he design of the FA-M3 R is based on the High-speed IPRS design concept, which aims to deliver the high-speed performance that developers have come to expect. Analysis has been conducted from every angle to deliver a controller that is the fastest device possible, is stable, links with other devices, and can be used over a network. The FA-M3 R is much faster than its predecessors and this increased speed yields higher operational stability, improved system accuracy and productivity, and greater scalability.

Reduces tact time and improves quality Fast scan time of 20,000 steps/ms*1 (four times faster than the previous model)
Ladder programs make ample use of application instructions to improve productivity, make operations easier to perform, and provide network and troubleshooting functions. To make the best use of these advanced functions and maximize system performance, computation speed has to be improved. The FA-M3 R is ideally suited for this task, being able to scan 20,000 steps per millisecond with conventional programs (approximately 50% application instructions) and improving scan time 4 to 11 times with more advanced application programs.

*1: This scan time will vary depending on program content and system configuration.

Instruction Processing Speed
Instruction F3SP53,F3SP58 LD/AND/OR 17.5 to 3.5 ns Timer 175 ns MOVE 70 ns Compare 70 ns Add/Subtract 105 ns Logical Operation 105 ns

Reduced I/O Response Time

Improves productivity and quality by decreasing response time Digital filter:

Min. 0 ms

Although the FA-M3 R reduces processing time by improving scan time, it increases the ratio of input/output time. As a solution, Yokogawa focused on total response time (input program → execution (processing) → output) and allowed variable time constants to be set to "0." This improved response time (circuit delay: Min. 100 μs). In addition, use of the high-speed contact output module (F3XD16-3H) will enable data input with a response time of 10 μs.

Instantaneous Response to Interrupt:

Interrupt response time: 100 μs
Response time for interrupts from DC input modules is as fast as 100 μs. This means that the system can immediately respond to changes in inputs, enabling instantaneous high-speed control.
Dual-purpose Sensor Control Function:Requires no separate controller Constant scan time for sensor control function: 200 μs min.

To respond at intervals of a few hundred microseconds, it is normal for a small, high-speed PLC or sensor controller to be installed separately from the main PLC. The FA-M3 R eliminates this redundancy with its own sensor control function that performs multi-scan processing and enables a high-speed response. This allows constant scanning to be performed concurrently to the main scan without being influenced by the main scan’s longer scan time (which is necessitated by advanced system functions). This is suitable for applications in which a high level of machining accuracy is required, since one block (program) can be run at high-speed constant intervals (200 μs or more) apart from the main scan.

Profibus DP with Wincc

With a PROFIBUS-DP connection you can visualize inputs/outputs of your I/Os directly in WinCC. For this WinCC provides a PROFIBUS channel for the connection of your PC to the PROFIBUS devices. Proceed as follows to create a PROFIBUS-DP connection in WinCC:

1.   Configuring the PC Station 

• Create a PC station in the SIMATIC Manager. This PC station represents your WinCC server or your WinCC single-station system. 

Fig. 1: Creating a PC station

• Open the Hardware Configuration editor by double-clicking on "Configuration". 
• Add an application to the rack. 

Fig. 2: Adding an application

• Add a CP5613 (or the PROFIBUS CP used) to the rack. 

Fig. 3: Adding CP5613

• Open the Properties of the CP by double-clicking on the CP. 
• Select the "Operating Mode" tab and enable the CP as master. Please make sure that you assign the application already created to the CP.

Fig. 4: Defining the operating mode

• Close the Properties dialog. Add the PROFIBUS slaves (e.g.: ET200M, ET200S etc.). Make sure that the slaves receive the correct PROFIBUS address. You set the PROFIBUS address directly on the slaves via DIP switches.
• Save and compile the configuration. 
• Load the configuration into the PC station. Make sure that the PG/PC interface is set to "PC Internal" and that the configuration just created corresponds to the actual configuration of your PC. You can check the actual configuration by starting the Station Configuration Editor (German: "Komponenten Konfigurator") either via the desktop or via the icon in the Start taskbar.

Fig. 5: Station Configuration Editor

2.   Configuring the WinCC Project 

• Start the WinCC Explorer and create a new WinCC project.
• Select "Tag Management" in the WinCC Explorer and open the pop-up menu with a right-click. 

Fig. 6: Adding a new driver

• Select "Add New Driver...". In the dialog that then opens you select "PROFIBUS-DP" and acknowledge the selection with "Open". 
• Now add a new connection to the channel ("right-click > New Driver Connection..."). 

Fig. 7: Adding a new driver connection

• Open the Properties of the connection and enter the PROFIBUS address of a slave. You need a new connection for each other slave. 

Fig. 8: Setting the slave address

• Open the system parameters of the PROFIBUS channel  ("right-click on PROFIBUS-DP > System Parameters"). 
• In the"CP board number" field you enter a "1" for the first CP. If there are two or more CPs in the PC, increase the number accordingly (up to a maximum of 4).

Fig. 9: Defining the CP board number

• Close the dialog with "OK". 
• Now you can create tags below the connection and configure them with the appropriate I/O addresses of the PROFIBUS slave.

Fig. 10: Creating tags

• Finally you can set the access point "CP_L2_1" to CP5613_5614 (PROFIBUS) by calling the configuration via "Start > SIMATIC > SIMATIC NET > Settings > Setting PC station". 

Fig. 11: S7 access points

• Select "Access Points" and double-click on CP_L2_1. In the dialog that opens you change the setting for the access point defined.

Fig. 12: Properties of CP_L2_1

Note:
If you are using more than on PROFIBUS CP, you have to select the relevant access points (CP_L2_x) accordingly.
CP1 > CPL2_1
CP2 > CPL2_2
CP3 > CPL2_3
CP4 > CPL2_4
