FOXBORO 0399085B工控卡件
LED亮起时的含义：模块内0错误（单位错误）
CS31系统总线上的1错误（总线错误）
2未使用
3断路（断线）
4溢流（超出范围）
5未使用
6未使用
7未使用诊断LED的含义标记在模块的前面板（英文）。
模块和中央单元上的错误消息再次重置，当错误消除后，否出现了新错误，错误消除已确认。错误消除后确认错误：按下测试按钮一段时间约5秒或使用PC或中央单元中的PLC程序再次按下并松开测试按钮对所有其他输入通道重复测试程序。从最后一个通道调用信息后，灯测试通过下次按下测试按钮执行。全部的模块的LED必须亮起。之后，位置地址DIL开关（CS31系统总线）显示约5秒。LED 0显示1号开关的位置（LED0到7属于开关1到8）。模拟值的显示未按下测试按钮时，8个LED显示
大致一个选定通道的模拟值。模拟输入的技术数据（适用于所有设置）每个模块的通道数8（成对配置）电气隔离与CS31系统总线接口线路频率抑制可配置为50 Hz或60 Hz或无输入信号延迟0（无RC组合）线路频率抑制（软件滤波器）20.0 ms，50 Hz线路频率16.7 ms，60 Hz线路频率输入端最大允许过压+/-30 V每个通道的刷新时间包括输入延迟和转换时间–线路频率抑制50/60 Hz（典型值）。
100毫秒–典型无线路频率抑制。
30毫秒–如果使用热电偶线路频率抑制50/60 Hz（典型值）。150毫秒如果不是全部刷新，则总刷新时间将缩短使用通道（有关配置，请参阅图5.2.5-3）。未使用的输入通道：如果未使用的Pt100/Pt1000通道将连接到跳线，则其电阻为0将假定极低温度的测量值。因此，将输出错误消息“Underflow”。为了防止出现此类错误消息，应按以下方式终止未使用的Pt100/Pt1000通道：120电阻Pt 100Pt 100 0，电阻为1200其他温度相关电阻器的连接：原则上，所有温度相关电阻器都可以连接到模块，而不是Pt100/Pt1000传感器。像配置，设置+5 V、+500 mV和+50 mV适用。如有必要必须使用PLC程序执行温度-电阻曲线。可以使用集成的电流汇。在里面这样做时，必须遵守以下规定：–所有串联电阻的电压降不得大于7 V（使用0.2 mA的电流接收器），2.5 V（使用2 mA的电流接收器）。
–集成电流汇的公差为+1.5%。此应用程序中的模块没有补偿。这与Pt100/Pt1000设置不同。
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.
