输出超范围：
指令输出超过24mA输出欠范围：指令输出小于0 mA。输入反馈错误：接线错误或硬件故障。注：如果为电路选择的输出反馈时间太短，可能会报告干扰诊断。如果发生这种情况，请增加反馈时间或禁用输出反馈测试。注：如果块在4-20mA范围外使用，如果命令输出值很低，可能会报告错误的输出反馈诊断。当指令输出小于1mA时，可以禁用反馈数据检查，当指令输出大于1mA时可以重新启用反馈数据检查。配置首先，必须使用手持监视器配置块：输入其设备号（串行总线地址）。输入其参考号（仅适用于IC600和IC550系列PLC）。注：如果块配置为离线，则必须正确接地，并在其串行1和串行2端子上安装75欧姆电阻器。有关说明，请参阅离散和模拟I/O块用户手册。其余功能可以使用手持监视器进行配置，也可以通过从主机向块发送写入配置数据报进行配置。功能电路/块工厂设置选择设备号块null 0到31（必须选择）参考地址块无取决于主机CPU类型波特率，Kbd块153.6 std 153.6 stt，153.6 ext，76.8，38.4报告故障电路是/否通道激活电路激活激活/非激活输入缩放电路1µA每eu+/-32767 eng单元0至+25000µA输出缩放电路1μA每eu+/-327677 eng单元1至+24000µA输入转换时间块400ms 16至400ms低报警电路0+/-32768 eng单元高报警电路+25000+/-3277 eng.单元输出反馈启用电路是/不输出反馈时间电路0ms 0至255ms保持最后状态电路否是/否输出默认电路4000+/-32767 eng.units BSM Present Block no是/否BSM Controller Block no yes/no输出默认时间块2.5秒2.5/10秒CPU冗余块无/备用配置保护块禁用启用禁用
Input Channel Usage
Block Operation These blocks have four independent inputs and two independent outputs. Input input channels use voltage to frequency converters and counters to convert analog currents to digital values. This module converts numerical values into engineering unit values and provides them to the CPU. EXC 24VDC P. S processor 16 bit counter V to F photoelectric isolation. The 100 COM GND enclosure grounded 47 IN filter has a 24 volt current loop power supply for each input, capable of supplying 25 mA. Each input is isolated from all other circuits on the block. The input accuracy is 0.1%. The input conversion time can be selected from 16 to 400ms. The resolution increases with the extension of the conversion time. The input resolution is 1mA, and the conversion time is 200ms. Two independent output circuits are electrically shared with each other and BSM output, but isolated from all other circuits on the block. The power supply of the output current loop is provided by the module. The output channel uses a dual 12 digit analog converter, which can independently control the current from 0mA to 24mA. The output resolution is 6mA. 24VDC P. S processor 16 bit counter V to F photoelectric isolation. Feedback amplifier. The current sensor current controller D/A feedback 12 bit D to A processor photoelectric data control isolation. RTN GND case grounding BSM switch 15VDC 15VDC OUT BSMBSM+two additional A to D channels are used to check the two output channels after the programmable stabilization time. If the feedback from these channels does not match the command value within 250mA, the block indicates a fault. Diagnosis_ The advanced diagnostics for the block provide the following information. The fault information can be cleared from the hand-held monitor or CPU. High alarm: input exceeds its high alarm limit Low alarm: input is lower than its low alarm limit Open circuit: input current is lower than 2mA Input out of range: signal exceeds 25mA Input out of range: current is negative or 0 mA.
Output out of range:
The instruction output exceeds the 24mA output under range: the instruction output is less than 0 mA. Input feedback error: wiring error or hardware failure. Note: If the output feedback time selected for the circuit is too short, interference diagnosis may be reported. If this happens, increase the feedback time or disable the output feedback test. Note: If the block is used outside the 4-20mA range, if the command output value is very low, incorrect output feedback diagnosis may be reported. When the command output is less than 1mA, the feedback data check can be disabled. When the command output is greater than 1mA, the feedback data check can be re enabled. To configure, you must first use the handheld monitor configuration block: enter its device number (serial bus address). Enter its reference number (for IC600 and IC550 series PLCs only). Note: If the block is configured offline, it must be properly grounded and a 75 ohm resistor must be installed on its Serial 1 and Serial 2 terminals. For instructions, refer to the Discrete and Analog I/O Block User Manual. Other functions can be configured using a handheld monitor or by sending a write configuration datagram from the host to the block.
