#USB IRDA ADAPTER SERIAL#
The Flow Tool app is a free download, so maybe installing it and checking to see whether the serial port can be assigned might be prudent. Sometimes Windows apps assume a given communications port and do not allow the user to change the port or the port settings. A PDM Modbus driver is available for download from the Siemens site.īut, it is not clear to me whether the Flow Tool app can be configured or "pointed at" a serial port other than the USB port in order to communicate long distances with the meter over copper wire using RS-232/485. I know PDM is capable of using Modbus on a serial port for communications with some Siemens level devices, so PDM can act as a Modbus master. RS 485 serial interface with MODBUS RTU (+/-/GND), multidrop with up to 32 devices withīut the mere presence of a comm port doesn't define what the comm port is used for.RS 232 serial interface with MODBUS RTU (Rx/Tx/GND), point to point with max.IrDA: Standard integrated infrared communication interface with MODBUS RTU protocol.The spec sheet says that there are two optional serial COM ports, RS-232 or RS-485: I assume PDM can be pointed to a virtual COM port where an IrDA USB adapter resides, but I've never done it. It appears to be a USB adapter on the PC side. The IrDA adapter is shown in the back of the Mag 8000 manual. The description of 'commissioning' in the Mag 8000 manual shows an open meter converter with the IrDA adapter attached to the meter cover with a rubber band (seriously. "Some information is accessible via the display whereas all information is accessible via the IrDA communication interface with the PDM software." It appears from a look at the Mag 8000 spec sheet and manual that the Mag 8000 is designed to communicate with the Flow Tool application program and PDM through an IrDA interface.
