S217 (FH Modems) Protocol Type

For most applications, the default value of 0 - resulting in transparent operation - will be maintained in this register. Setting this register to a value of 1 specifies MODBUS operation, in which the modem will frame the output data and comply with MODBUS specifications. S217=2 configures the modem for DF1 filtering. In this mode, the PLC’s address must match the Unit Address of the modem. Data not intended for a specific PLC/Modem pairing will be blocked from passing through the modem to the attached PLC.

对于大多数应用程序,默认值0 –即按照透明协议操作——在这个寄存器将保持。设置这个寄存器值为1表示MODBUS协议操作,在调制解调器将帧输出数据和遵守MODBUS规范。S217 = 2配置调制解调器DF1过滤。在这种模式下,PLC的地址必须匹配调制解调器单元地址。不是用于一个特定的PLC /调制解调器配对的数据会阻止通过调制解调器传输到连接PLC。

This register displays the maximum recorded ‘signal strength received’ since the unit was last placed into Data mode. (Online).这个寄存器显示以来的最高记录的信号强度收到单位最后一次放入数据模式。(在线)

S238 Hopping Mode

Hopping mode register (S238) is preset by manufacturer. It is a read-only register for the end user. S238 controls the modem either hopping on pattern or on frequency table.跳跃模式寄存器(S238)由制造商预设。这是一个只读寄存器为最终用户。S238控制调制解调器上跳跃模式或频率表。

1 - Hopping on frequency table 频率表跳变 2 - Hopping on channel 频道跳变 3 - Hopping on frequency频率跳变

S244 (FH Modems) Channel Request Mode

Channel Request Mode ?on‘ (default), allows a Remote modem which has data to send to request from the Master permission to do so. When granted, the Remote will be allowed to transmit all of its data (no other Remotes may transmit during this period), upon completion of which it will release the channel. This feature eliminates collisions which would otherwise occur if a number of Remotes were all trying to transmit at the same time.

TDMA mode is discussed in detail in previous sections. It relates to Channel Requests in that, in TDMA mode, the Master does not allow such requests from Remotes; the Master sequences through a list of Remotes, giving each one in turn an opportunity to transmit.

通道请求模式―上‖(默认),允许远程调制解调器从主数据发送给请求的权限。授予时,将允许远程传输的数据(没有其他遥控器可能传播在此期间),完成后,它将释放通道。这个特性可以消除碰撞会发生如果数量的遥控器都试图同时传输。

TDMA模式是在前一节中详细讨论。相关信道请求,在TDMA模式下,主不允许这样的请求从遥控器;主序列通

过遥控器的列表,给每个人依次传播的机会。

S248 (FH Modems) Sync Timeout

This register defines how many hop intervals where the slave does not receive a synchronization packet from the master, before it will become unsynchronized and begins to search for a master. 这个寄存器定义多少跳间隔,奴隶没有收到主同步数据包,之前它将成为同步并开始寻找主人。

S251 (FH Modems) Master Hop Allocation Timeout

In TDMA mode (see S244) this register determines how long, in hop intervals, the Master will wait for a Remote to either (a) begin to send data or (b) indicate that it has completed sending all of its data, prior to the Master sequencing to the next Remote to be given permission to transmit.

在TDMA模式(见S244)这个寄存器决定，主站将等待多长时间远程(a)开始发送数据或(b)表明它已经完成发送它的所有数据,掌握测序前下一个远程传输得到许可。

Displaying Frequency Table

ATP0?Displays the current frequency table all at once. There are 50 channels in the frequency table. 显示频率表

ATP0?显示当前频率表。有50个频道的频率表。

5.1.5.2 ATP0 and ATP1 Commands

The command ATP0 is used to create/modify the primary frequency table, ATP1 is for the secondary frequency table. Since these two commands have the same syntax, the following will use ATP0 as an example. Both tables (ATP0 & ATP1) must be populated before the modem will go online.

Editing Frequency Table

ATP0= command allows a user to edit the frequency table channel by channel. The user can press ESC to exit from editing mode. Any valid frequencies typed will be saved into the table automatically. A valid input format is as follows, ####.######

The value given here is in MHz.

The BACKSPACE key can be used to correct mistakes when typing a frequency. Once ENTER is pressed, the value will be accepted if it has the right format. An accepted value can NOT be modified with the BACKSPACE key. If changing is desired, the table has to be entered. 5.1.5.2 ATP0和ATP1命令

命令ATP0用于创建/修改主频率表,ATP1是次要的频率表。因为这两个命令具有相同的语法,以下将使用ATP0为例。两个表(ATP0 & ATP1)在调制解调器上线之前必须填充。 编辑频率表

ATP0 =命令允许用户编辑的频率表通道的通道。用户可以按ESC退出编辑模式。任何有效的频率输入将被自动保存到表。

一个有效的输入格式如下, # # # # # # # # # # 此处给出的值是在兆赫。

退格键可以用来纠正错误时输入频率。一旦进入,值将被接受,如果有正确的格式。一个公认的退格键值不能修改。如果需要改变,表必须输入。
