ABB TotalFlow Interface Reference EPDOC-X340-en-501A
Property
Description Fastest Scan Period Define the fastest possible scan period (in seconds) that dynamic scanning will scan point parameters on this controller. The default is 15 seconds. The dynamic scanning period does not affect the static scanning rate for a parameter. For example, if the scanning rate for a parameter is 10 seconds, and the dynamic scanning rate for the controller is 15 seconds, the parameter will still be scanned at a period of 10 seconds. Station ID ID of the controller, specified when the controller was configured. Value must be between 1 and 10 characters. Device Type The type of device connected to the controller. The only supported device type is FCU . TotalFlow Protocol The ABB Totalflow protocol that will be used to communicate with this controller. The only valid protocol is DB2 . Data Block size The acceptable size of a data packet. The value must be between 64 and 4096 bytes, with the default value being 1024 bytes. Baud Rate The data transfer rate for the device. The value must be 300, 1200, 2400, 9600, 19200, 38400, or 57600 , with the default value being baud rate being 9600 . The Baud Rate must be defined, even for TCP connections, as it is used to calculate timeouts within the protocol handling. Packet Size The total size of the data exchange. This value must be greater or equivalent to the Data Block size . The valid range is 1KB to 32KB, and the default packet size is 8KB . Link Time The number of seconds for the power-save mode of the device. Also referred to as the device listen interval or cycle, it indicates how often the device checks for data at its serial communications ports. If no data is present, the device returns to power-save mode. Devices do not use this value if listening on their Ethernet port, but the host uses this value to determine the number of addressing frames to send since the host cannot assume that the device is listening on an Ethernet port. The value must be 0, 1, 2, or 4 , with the default value being 0 . Retries The number of retries to be performed for DB2 and DB2_EX requests. The value must be between 0 and 9 , with the default value being 0 . 20 Chapter 2 - ABB Totalflow channel and controller reference |
