Information regarding the communications features of specific Vision models is available from your local Unitronics distributor, or [email protected].
Below is a general description of Vision communication features. For details, refer to the Vision Communications manual.
Com Ports
Than q for your reply deepak and i am a new to network programming can you give mo more information about this serial port communication with asp.net. Serial communications can be done via either direct to physical serial port connected to the computer or via a USB to serial converter interface. If the device do require a serial port and your computer don’t have any, you can make use of such converters easily.
Serial | All Vision controllers comprise RS232 serial communication ports. RS232/RS485 adaptors are available by separate order. Certain models, such as the Vision120, support both RS232 and RS485. For details on communications hardware settings, refer to the User Guides and documentation supplied with relevant models. |
USB | USB ports support project and OS download only, and are built into ERROR: Variable (USBprogramming) is undefined. controllers. Before you can use it, = 4 && typeof(BSPSPopupOnMouseOver) 'function') BSPSPopupOnMouseOver(event);'>you must install the USB driver to support USB function; this is available from Connection> Communication PC Settings> USB tab. Note that COM port 1 function is suspended when the USB port is physically connected to the PC. |
CANbus | Separate CANbus ports are built into specific controller models. |
Ethernet | Ethernet ports are available by separate order. |
Note ♦ | All ports can be used simultaneously, with the exception of the USB port in ERROR: Variable (USBprogramming) is undefined. . |
♦ | Standard programming cables do not provide connection points for pins 1 and 6. |
Initializing COM ports
Serial and CANbus communication ports must be initialized in your control program using the COM Init FB, located on the FB's menu.
The Ethernet port must be initialized using the Ethernet Card Init FB, located under Ethernet on the FB's menu.
Data Communications Options
Data Communications include all of the options shown below:
GPRS
Communication FBs
SMS messaging
GPRS
MODBUS (serial)
MODBUS IP (Ethernet)
Communications Protocol FB
PC-Vision communications
SD Card Remote Access
SD Card Explorer
Set Same Terminator for Read and Write Communication
Create a connection to a serial port device using serialport.
Set both the read and write terminators to 'CR/LF'.

Confirm the change.
Set Different Terminators for Read and Write Communication
Create a connection to a serial port device using serialport.
Set the read terminator to 'CR' and the write terminator to 10.
Confirm the change.
The first element in the array is the read terminator and the second is the write terminator.
Write and Read Line of ASCII Data from Serial Port Device
Create a connection to a serial port device. In this example, the serial port at COM3 is connected to a loopback device.
Check the default ASCII terminator.
Set the terminator to 'CR' and write a string of ASCII data. The writeline function automatically appends the terminator to the data.
Write another string of ASCII data with the terminator automatically appended.
Serial Port Communication In Asp.net C#
Since the port is connected to a loopback device, the data you write to the device is returned to MATLAB®. Read a string of ASCII data. The readline function returns data until it reaches a terminator.
Read a string of ASCII data again to return the second string that you wrote.
