The Tendency to Power monitoring: Power monitoring total solution based on CAN bus power meter
The
PM-213x-CAN series power meter provides the CAN bus interface for communication. It inherits all CAN bus features so that the data collection of the real-time power consumption information becomes more reliable and faster. In order to applying the
PM-213x-CAN with the PC or PAC simply and conveniently, the master solutions of the
PM-213x-CAN are released. Through downloading the power meter management firmware into the
I-8120W or
PISO-CM100U, the power meter masters are given. Utilizing these masters brings you the efficient solutions in power control and monitor system, especially in collecting the data from a lot of remote power meters.
The
I-8120W is used with the PAC which may be XPAC, WinPAC or ViewPAC. The XPAC with the WES and Windows CE 6.0 platform gives you high performance PAC solutions. The WinPAC and ViewPAC are the economic PACs with the Windows CE 5.0 platform. The ViewPAC has some buttons and touch screen, which are suited for monitoring and controlling in the field. If you prefer to use the PC for applications, the
PISO-CM100U can satisfy you. After finishing the installation of the
I-8120W or
PISO-CM100U, it manages all the
PM-213x-CAN power meters and collects all power data automatically. Then, you can call the provided APIs of VC++, BCB or VS .NET to configure parameters or get the data from power meters. Besides, there is a free management utility. It helps you set up the power manage system and diagnose your application quickly.
PAC Utility with the I-8120W
PC Utility with the PISO-CM100U
The Master Firmware of the power meter Features:
- Follow CiA CAN 2.0B specification.
- Support both PM-2133-CAN and PM-2134-CAN series power meter.
- Support programmable baud rate 125 kbps, 250 kbps and 500 kbps.
- Manage up to 45 power meters with single I-8120W or PISO-CM100U.
- Collect power information of all power meters automatically.
- The scan time of 45 power meters is 368ms at 500 Kbps.
- Monitor the communicating status of the power meters.
- Provide VC6, BCB, and VS.Net APIs and demos.
- Provide a utility tool for configuring parameters and diagnosing applications.
General Applications
The scan time comparison with the RS-485 and CAN power meter
- Increasing the amount of the power meters increases RS-485 scan time faster than CAN bus.
- When expanding the network in the future, CAN bus is more flexible than RS-485 bus.
- In harsh environments with electrical noise, CAN bus has better anti-noise ability.
