SBS VIPC616輸入特性模件,VIPC616英文使用說明
Horner APG RTU接口模塊。HE693RTU900是一款Modbus從接口，允許與RS232或RS485進行Modbus通信。這個HE693RTU940相當于HE693RTU900，增加了14.4k bps調制解調器。RTU模塊允許Modbus主機訪問PLC參考數據，就像它是Modbus I/O一樣。
可以使用標準Modbus命令訪問該數據，例如讀取/強制線圈和讀取/預設寄存器。要使用有限的Modbus命令集訪問大多數PLC數據類型，
SBS VIPC616輸入特性模件這些命令中提供的參考被細分為允許訪問特定數據表。可訪問的數據類型為：%M、%I、%Q、%T、%R、%AI、%AQ。始終允許讀取和寫入數據。讀寫數據包，最多2000個離散或125個支持模擬值。信息接收LED和Modbus診斷和異常還支持命令以提供輕松的設置和故障排除。HE693RTU940具有按異常報告功能。該功能使模塊能夠發出命令和監控通話狀態。
端口類型和相關幀協議參數的配置可以通過以下方式輕松完成：
手持編程器或提供外部輸入/輸出模塊定義的包含信息PLC配置軟件。HE693RTU900和HE693RTU940都支持高達的波特率115.2K，用于ASCII或RTU模式下的RS232或RS485。HE693RTU940支持波特率上升調制解調器端口為14.4k。請注意，停止位和奇偶校驗的數量有限制選擇。
Modbus slave interface which allows modbus communications with either RS232 or RS485. The
HE693RTU940 is equivalent to the HE693RTU900 with the addition of a 14.4k bps modem.
The RTU Module allows a Modbus master to access PLC reference data as though it were Modbus I/O.
This data may be accessed using standard Modbus commands such as Read / Force Coils and Read /
Preset Registers. To access most of the PLC data types with the limited set of Modbus commands,
references provided in these commands are subdivided into regions which allow access to a particular
data table. Accessible data types are: %M, %I, %Q, %T, %R, %AI, %AQ.
Reading and writing data is always allowed. Read and Write packets of up to 2000 discrete or 125
analog values are supported. Message reception LED’s and Modbus Diagnostic and Exception
commands are also supported to provide easy setup and troubleshooting. The HE693RTU940 has the
Report-By-Exception feature. This feature gives the module the ability to originate commands and
monitor call status.
Configuration of the port type and associated frame protocol parameters is easily accomplished through
the Hand Held Programmer or providing the included information of a foreign I/O module definition with
PLC configuration software. Both the HE693RTU900 and HE693RTU940 support baud rates of up to
115.2K for RS232 or RS485 in either ASCII or RTU modes. The HE693RTU940 supports a baud rate up
to 14.4k for the modem port. Please note that there are limitations in the number of stop bits and parity
