1756-EN2TXT模块,1756-EN2TXT使用区域
NTDI01终端单元只能终止具有IMHSS02功能的HSS模块。要安装NTDI01终端装置：参考TDI终端装置产品说明书或附录E选择所需的双工分流设置。
2.按照TDI产品说明中的步骤安装现场终端面板的终端装置。
3.将伺服阀、线性可变差动变压器、数字I/O、24 VDC和I/O的接线连接至公用电路终端装置。
4.按照TDI产品说明中的步骤进行连接将NKHS03电缆的J1连接到HSS模块的MMU插槽。
将J2连接到终端装置上的P1。绑好J3腿使其固定在一边。
1756-EN2TXT模块初始IMHSS03双列直插式开关设置IMHSS03模块有五个双列直插式开关和31个跳线必须对其进行配置。双列直插式开关设置适用依靠的本节中的信息涵盖了开关初始安装所需的设置。完成中的步骤本部分为模块的安装准备程序用于自动校准和调谐。
双列直插式开关S1-输入/输出扩展器总线地址双列直插式开关S1是一个八极双列直插式开关。极点三通其中八个DIP开关设置输入/输出扩展器总线地址。极一个调用模块诊断。有关diagnos双列直插式开关设置，请参阅第6节。将HSS模块输入/输出扩展器总线地址设置为任何未使用的地址二进制地址从零到63。双列直插式开关极1和2必须处于关闭位置才能正常运行。使用电极3到8设置地址。表3-1列出了示例输入/输出扩展器总线地址双列直插式开关设置。
The NTDI01 termination unit can terminate only an HSS mod
ule having IMHSS02 functionality. To install the NTDI01 termi
nation unit:
1. Refer to the TDI termination unit product instruction or
Appendix E to select the required dipshunt settings.
2. Follow the steps in the TDI product instruction to mount
the termination unit to the field termination panel.
3. Connect the wiring from the servo valve, linear variable dif
ferential transformer, digital I/O, 24 VDC and I/O common to
the termination unit.
4. Follow the steps in the TDI product instruction to connect
J1 of the NKHS03 cable to the MMU slot for the HSS module.
Connect J2 to P1 on the termination unit. Tie wrap the J3 leg
of the NKHS03 cable so that it is secured out of the way.
INITIAL IMHSS03 DIPSWITCH SETTINGS
The IMHSS03 module has five dipswitches and 31 jumpers
that must be configured. Dipswitch settings are application
dependent. The information in this section covers the switch
settings needed for initial installation. Complete the steps in
this part of the installation procedure to prepare the module
for automatic calibration and tuning.
Dipswitch S1 - I/O Expander Bus Address
Dipswitch S1 is an eight-pole dipswitch. Poles three through
eight of this dipswitch set the I/O expander bus address. Pole
one invokes module diagnostics. Refer to Section 6 for diagnos
tic dipswitch settings.
Set the HSS module I/O expander bus address to any unused
binary address from zero to 63. Dipswitch poles one and two
must be in the closed position for normal operation. Use poles
three through eight to set the address. Table 3-1 lists examples
of I/O expander bus address dipswitch settings. See Figure 3-1
