SBS VIPC616输入特性模件,VIPC616英文使用说明
Horner APG RTU接口模块。HE693RTU900是一款Modbus从接口，允许与RS232或RS485进行Modbus通信。这个HE693RTU940相当于HE693RTU900，增加了14.4k bps调制解调器。RTU模块允许Modbus主机访问PLC参考数据，就像它是Modbus I/O一样。
可以使用标准Modbus命令访问该数据，例如读取/强制线圈和读取/预设寄存器。要使用有限的Modbus命令集访问大多数PLC数据类型，
SBS VIPC616输入特性模件这些命令中提供的参考被细分为允许访问特定数据表。可访问的数据类型为：%M、%I、%Q、%T、%R、%AI、%AQ。始终允许读取和写入数据。读写数据包，最多2000个离散或125个支持模拟值。信息接收LED和Modbus诊断和异常还支持命令以提供轻松的设置和故障排除。HE693RTU940具有按异常报告功能。该功能使模块能够发出命令和监控通话状态。
端口类型和相关帧协议参数的配置可以通过以下方式轻松完成：
手持编程器或提供外部输入/输出模块定义的包含信息PLC配置软件。HE693RTU900和HE693RTU940都支持高达的波特率115.2K，用于ASCII或RTU模式下的RS232或RS485。HE693RTU940支持波特率上升调制解调器端口为14.4k。请注意，停止位和奇偶校验的数量有限制选择。
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
