ModScan Overview The ModScan application operates as a MODBUS mastermodbus_protocol device in either RTU or ASCII transmission modes. ModScan may be used to access and modify data points contained in one or more MODBUS slave devices connected to the PC via a serial port, modem, or network. ModScan supports the standard MODBUS message types 01-06, 15 & 16, as well as providing the ability for you to exercise special features of a slave device by transmitting custom command strings and observing the response. ModScan is a useful test and diagnostic tool for verifying the proper slave response to MODBUS queries as well as being a low cost data collection tool for interfacing data into PC database and spreadsheet applications. 1.1 Document/View Architecture ModScan utilizes the standard Windows Multiple-Document-Interface, (MDI), architecture for displaying modbus data to the user. Each document represents a series, (array), of modbus data points identified by the following parameters: Slave Device Address Represents the physical device attached to the modbus network Data Type Internal data representation, (i.e. input, coil, register) Data Address Point address within the device Length Number of points to scan/display Associated with each document is also a timer, which is used to periodically scan new data from the defined slave and refresh the display. The modbus data definition is accessible from the ModScan menu or via edit controls in the top splitter window of the document display. As new data is obtained from the slave device, it is written to the bottom splitter window in one of several formats, depending upon your preference. The size of each document display window is adjustable via the splitter control. ...展开收缩
