XPOW3720: Power Measurement 3720 ACM Protocol Driver v10.0


XPOW3720: Power Measurement 3720 ACM Protocol Driver

General Information:


XPOW3720 driver allows you to connect with POWER MEASUREMENT 3720 ACM Power Meter Series.

The link is established using the PML 3720 serial communications protocol over a RS-232 or RS-485 phisical layer; however, you should consider that the RS-485 specification allows for multiple devices (up to 32) on a single loop, whereas the RS-232C allows for only a single device.

This driver includes one global command that can be used to read the most relevant variables from the PML 3720 ACM. If you need to read other parameters or write any information to the device, consider using the XMODBUSB driver (modbus binary protocol) which is also supported by this Power Measurement family.

Typical communication settings:
8 Data bits, no parity and 1 stop bit. Baudrate is configurable.

If you cannot communicate or if you are using RS-485 to connect to the device, you should set the RTS signal during the communication. This can be done by setting the RTSEnable argument when calling the read and write methods. If you still cannot communicate, check that your RS-485 cables are not inverted.

Licenses

The licenses of all our drivers are unlimited in terms of the number of machines where they can be used, the number of I/O that can read or written, and the number of components that can be included in each application.

After purchasing a license, the owner can use the driver and all its components to assemble and distribute as many applications to as many users as needed.

The license owner retains full control of his applications by deciding himself what target machines can they be run at. For this, each driver is provided with two runtime license management tools: GetPCId.exe and MakeLic.exe.
