70PR05B-ES HESG332204R0001指定每个块中的字数在模块和处理器之间传输。指定端口和命令是否为：模块启动时激活。类型主、从或带直通的从机此参数指定端口的设备类型模仿。有关详细信息，请参阅从属模式（第72页）从机通过选项。

Enron Daniels是或否使用浮点数据偏移量。协议RTU或ASCII指定端口的Modbus协议。波特率多个选项指定端口的波特率。奇偶性无、奇数，即使指定奇偶校验错误检查的类型。

所有设备打开此端口必须使用相同的奇偶校验设置。数据位7或8设置由协议通过此端口通信的所有设备必须使用相同数量的数据位。停止位1或2设置表示结束的停止位的数量数据流中的字符。对于大多数应用程序，请使用一个停止位。

对于需要更多时间的较慢设备：要重新同步，请使用两个停止位。所有设备通过此端口通信必须使用相同的停止位的数量。0到65535毫秒的RTS设置准备就绪后延迟的毫秒数发送（RTS）在数据传输之前被断言。RTS Off 0到65535毫秒设置最后一次延迟后的毫秒数在设置RTS调制解调器信号之前发送数据字节低的

70PR05B-ES HESG332204R0001 Specifies that the number of words in each block is transferred between the module and the processor. Specifies whether ports and commands are: activated when the module starts. Type Master, Slave, or Slave with Passthrough This parameter specifies the device type imitation of the port. For more information, see Slave Mode (page 72) Slave Through options.

Enron Daniels Yes or No to use floating-point data offsets. Protocol RTU or ASCII Modbus protocol for the specified port. Baud Rate Multiple options specify the baud rate of the port. Parity None, odd, even if the type of parity error check is specified.

All devices must use the same parity setting to open this port. Data bits 7 or 8 Set that all devices communicating through this port by protocol must use the same number of data bits. Stop bit 1 or 2 Sets the number of stop bits that represent the end of the character in the data stream. For most applications, use a stop bit.

For slower devices that require more time: To resynchronize, use two stop bits. All devices communicating through this port must use the same number of stop bits. The number of milliseconds of delay after RTS Settings are ready to send (RTS) is asserted before data transmission. RTS Off 0 to 65535 ms Sets the number of milliseconds after the last delay before setting the RTS modem signal to send data bytes low
