The table below lists functions and subroutines frequently used for controlling I/O devices. For more detailed information about each function, please refer to the Functions for Communication section in Appendix 1. Please note that functions return a value, while subroutines do not.
Function | OpenPort(PortNo., BaudRate, Parity, Data Bit, Stop Bit) | Opens the serial port. |
Function | ClosePort(PortNo.) | Closes the serial port. |
Function | SendByte(PortNo., Data) | Sends byte data with the selected port. |
Function | SendString(PortNo., Data) | Sends string data with the selected port. |
Function | ReceiveByte(PortNo., Data) | Receives data with the selected port. |
Function | GetCommStatus(“DeviceName”, “StationName”) | Checks the selected station’s communication status. |
Subroutine | EnableDriver(“DeviceName”, “StationName”, Enable/Disable) | Controls the selected station’s communication. |
To share Xpanel tags with CIMON-SCADA, or to configure Xpanel as a Modbus Slave, see the Data Server chapter. Note that the 'Xpanel Data Server' feature must be configured for SCADA to be able to communicate with the Xpanel device.
To configure Xpanel as a data bridge between devices, see the Data Bridge chapter.
To send and receive contiguous blocks of data to/from I/O devices, see the Recipe chapter.
