FOXBORO 0399085B工控卡件
LED亮起時的含義：模塊內0錯誤（單位錯誤）
CS31系統(tǒng)總線上的1錯誤（總線錯誤）
2未使用
3斷路（斷線）
4溢流（超出范圍）
5未使用
6未使用
7未使用診斷LED的含義標記在模塊的前面板（英文）。
模塊和中央單元上的錯誤消息再次重置，當錯誤消除后，否出現(xiàn)了新錯誤，錯誤消除已確認。錯誤消除后確認錯誤：按下測試按鈕一段時間約5秒或使用PC或中央單元中的PLC程序再次按下并松開測試按鈕對所有其他輸入通道重復測試程序。從最后一個通道調用信息后，燈測試通過下次按下測試按鈕執(zhí)行。全部的模塊的LED必須亮起。之后，位置地址DIL開關（CS31系統(tǒng)總線）顯示約5秒。LED 0顯示1號開關的位置（LED0到7屬于開關1到8）。模擬值的顯示未按下測試按鈕時，8個LED顯示

100毫秒–典型無線路頻率抑制。
30毫秒–如果使用熱電偶線路頻率抑制50/60 Hz（典型值）。150毫秒如果不是全部刷新，則總刷新時間將縮短使用通道（有關配置，請參閱圖5.2.5-3）。未使用的輸入通道：如果未使用的Pt100/Pt1000通道將連接到跳線，則其電阻為0將假定極低溫度的測量值。因此，將輸出錯誤消息“Underflow”。為了防止出現(xiàn)此類錯誤消息，應按以下方式終止未使用的Pt100/Pt1000通道：120電阻Pt 100Pt 100 0，電阻為1200其他溫度相關電阻器的連接：原則上，所有溫度相關電阻器都可以連接到模塊，而不是Pt100/Pt1000傳感器。像配置，設置+5 V、+500 mV和+50 mV適用。如有必要必須使用PLC程序執(zhí)行溫度-電阻曲線?？梢允褂眉傻碾娏鲄R。在里面這樣做時，必須遵守以下規(guī)定：–所有串聯(lián)電阻的電壓降不得大于7 V（使用0.2 mA的電流接收器），2.5 V（使用2 mA的電流接收器）。
–集成電流匯的公差為+1.5%。此應用程序中的模塊沒有補償。這與Pt100/Pt1000設置不同。
Meaning of the LEDs if lighting up:
0 Error inside the module (Unit error)
1 Error on the CS31 system bus (Bus error)
2 not used
3 Open circuit (Cut wire)
4 Overflow (Out of range)
5 not used
6 not used
7 not used
The meaning of the diagnosis LEDs is labelled on the
front panel of the module in English.
The error messages on the module and in the central unit
are reset again, when the errors have been eliminated, no
new errors have occurred and the error elimination has
been acknowledged.
Acknowledging an error after error elimination:
by pressing the test button for a period of
ca. 5 seconds or with the PC or with the PLC program in the central unit
Pressing and releasing the test button further times, the
test procedure repeats for all of the other input channels.
After calling information from the last channel, a lamp test
is carried out by pressing the test button the next time. All
LEDs of the module must light up. After that, the positions
of the address DIL switches (module address on the
CS31 system bus) is displayed for a period of ca. 5
seconds. LED 0 shows the position of switch No. 1 (LEDs
0 to 7 belong to the switches 1 to 8).
Display of an analog value
When the test button is not pressed, 8 LEDs display the
analog value of one selected channel roughly. Technical data of the analog inputs (applies for all settings)
Number of channels per module 8 (configurable in pairs)
Electrical isolation versus the CS31 system bus interface
Line frequency suppression configurable for 50 Hz or 60 Hz or none
Input signal delay 0 (no RC combination)
Line frequency suppression (software filter) 20.0 ms with 50 Hz line frequency
16.7 ms with 60 Hz line frequency
Permissible overvoltage at the inputs max. +/– 30 V
Refresh time per channelincl. input delay and conversion time
– line frequency suppression 50/60 Hz typ. 100 ms
– no line frequency suppression typ. 30 ms
– if thermocouples are used
with line frequency suppression 50/60 Hz typ. 150 ms
The total refresh time will be shorter if not all of
the channels are used (for configuration see
Fig. 5.2.5–3).Unused input channels:
If unused Pt100/Pt1000 channels would be connected to a wire jumper, its resistance of 0 would pretend the
measuring value of a very low temperature. As a result, the error message ”Underflow” would be output. In order to
prevent such error messages, unused Pt100/Pt1000 channels should be terminated as follows:
Pt 100 by a resistor of 120
Pt 100 0 by a resistor of 1200
Connection of other temperature–dependent resistors:
In principle, all temperature–dependent resistors can be connected to the module instead of Pt100/Pt1000 sensors. As
configurations, the settings + 5 V, + 500 mV and + 50 mV are suitable. If necessary, the linearization of the
temperature–resistance curve must be performed with the PLC program. The integrated current sinks can be used. In
doing so, the following has to be observed:
– The voltage drop over all resistors circuited in series may not be greater than
7 V (using the current sink of 0.2 mA),
2.5 V (using the current sink of 2 mA).
– The tolerance of the integrated current sinks is + 1,5 %. There is no compensation by the module in this application.
This is a difference compared with the Pt100/Pt1000 settings.
