HIMA B5233-2模块模拟量输入模块
块检测模块自动检查是否存在端子块。TB LED指示该模块接线板的状态。当接线板存在时，它是绿色的，如果没有，它是红色的。当从系统中配置的模块插入或移除接线板时，故障会自动记录在CPU I/O故障表中。故障类型为Field fault（现场故障），故障描述表明故障是“接线板丢失”还是“接线板增加”。如果在存储配置时不存在接线板，则会记录“接线板丢失”故障。模块状态参考的第2位指示接线板的状态。要启用模块状态报告，必须配置模块状态参考。运行期间，PLC必须处于I/O启用模式，以便在参考存储器中扫描和更新当前模块状态。10.3.15现场接线：ALG704和ALG708下表列出了非隔离模拟输出模块的接线连接。没有屏蔽端子。对于屏蔽，请沿背板底部将电缆屏蔽连接到接地棒。此电流通道2电压输出通道2电流输出公共通道4电压输出通道4电流输出公共输出通道1电压输出通道1电流输出公共信道3电压输出通道3电流输出模块8通道电流/电压隔离：IC695ALG808 PACSystems*RX3i系统手册第12节GFK-2314T 9月。2019模拟输出模块470模块正常现场状态TB IC695ALG808 Q1 Q2 Q4 Q5 Q6 Q7 Q8图308:IC695ALG008模拟电流/电压输出隔离模块IC695AL808提供八个可配置的电压或电流输出通道。可为以下输出范围配置模拟通道：▪ 电流：0至20mA，4至20mA▪ 电压：±10 Vdc，0至10 Vdc模块必须位于RX3i通用背板中。这些模块可与盒型（IC694TBB032）、扩展盒型（IC 694TBB132）、弹簧型（IC6914TBS032）或扩展弹簧型（IC 6914TBS132）接线板一起使用。扩展接线板提供屏蔽布线所需的额外护罩深度。端子板订购GFK-2314T 2019年9月模拟输出模块471 10.4.3 LED：IC695ALG808模块OK LED指示模块状态。现场状态LED指示外部+24V直流电源是否存在且高于最低水平，以及是否存在故障。所有LED均由背板电源总线供电。LED指示模块正常开启绿色：模块正常且已配置。快速闪烁绿色：模块正在执行通电顺序。绿色或琥珀色缓慢闪烁：模块正常，但未配置。关闭：模块故障或无背板电源现场状态为绿色，任何已启用通道上无故障，存在接线板，且现场电源存在。ON琥珀色和TB绿色：接线板已安装，至少一个通道出现故障，或现场电源不存在。ON琥珀色和TB红色：接线板未完全移除，检测到现场电源。OFF和TB红色：接线板不存在，未检测到现场电源。TB ON红色：接线板不存在或未完全就位。
Block Detection The module automatically checks for the presence of a Terminal Block. The TB LED indicates the state of the terminal block of this module. It is green when the Terminal Block is present or red if it is not. Faults are automatically logged in the CPU I/O Fault table when the terminal block is inserted or removed from a configured module in the system. The fault type is Field Fault and the fault description indicates whether the fault is a "Loss of terminal block" or an "Addition of terminal block". If a Terminal Block is not present while a configuration is being stored, a "Loss of terminal block" fault is logged. Bit 2 of the Module Status Reference indicates the status of the terminal block. To enable Module Status reporting, the Module Status Reference must be configured. During operation, the PLC must be in an I/O Enabled mode for the current Module Status to be scanned and updated in reference memory. 10.3.15 Field Wiring: ALG704 and ALG708 The following table lists wiring connections for the Non-Isolated Analog Output Modules. There are no shield terminals. For shielding, tie cable shields to the ground bar along the bottom of the backplane.

Analog channels can be configured for the following output ranges: ▪ Current: 0 to 20mA, 4 to 20mA ▪ Voltage: ±10 Vdc, 0 to 10 Vdc The module must be located in an RX3i Universal Backplane. These modules can be used with a Box-style (IC694TBB032), Extended Box-style (IC694TBB132), Spring-style (IC694TBS032), or Extended Spring-style (IC694TBS132) Terminal Block. Extended terminal blocks provide the extra shroud depth needed for shielded wiring. Terminal Blocks are ordered GFK-2314T Sept. 2019 Analog Output Modules 471 10.4.3 LEDs: IC695ALG808 The Module OK LED indicates module status. The Field Status LED indicates whether the external +24Vdc power supply is present and is above the minimum level and whether or not faults are present. All LEDs are powered from the backplane power bus. LED Indicates Module OK ON Green: Module OK and configured. Quick Flashing Green: Module performing power-up sequence. Slow Flashing Green or Amber: Module OK but not configured. OFF: Module is defective or no backplane power present Field Status ON Green No faults on any enabled channel, Terminal Block is present, and field power is present. ON Amber and TB Green: Terminal Block is installed, fault on at least one channel, or field power is not present. ON Amber and TB Red: Terminal Block not fully removed, field power detected. OFF and TB Red: Terminal block not present and no field power is detected. TB ON Red: Terminal block not present or not fully seated.
