VisSim/Serial – Add-On

VisSim/Serial lets you read and write standard RS232 serial bytes from the VisSim block diagram via Serial read/write blocks. VisSim/Serial lets you configure serial port settings including baud rate, parity and stop bits. You can also choose whether you want to read single characters or complete strings. You can use Serial blocks for remote sensing, data exchange or remote control. You can easily log data, plot, strip-chart or run a virtual plant or controller for model based development. To read or write serial data from VisSim, you must have an RS-232 connection, which is quite common on PCs and laptops. Then just insert and wire Serial Read and/or Serial Write blocks into a diagram and then click the Go button. You may transmit and receive from any number of different IP addresses in a single diagram. The serial Read and serial Write blocks let you read data from and write data to serial ports.
