如果通道2出现高报警条件，应触发I/O中断块。▪ 配置高报警条件。▪ 在模块配置中设置通道2的高报警中断启用标志。通道2的参考地址对应于%AQ00003（每个通道2个字），因此应为“I/O中断”类型设置中断程序块调度属性，并将“%AQ0003”设置为触发器。故障报告和中断这些模块具有诊断报告和中断的单独启用/禁用选项。通常，禁用配置中的诊断（如低/高报警或过高/过低范围）意味着其诊断位从未设置。但是，如果为某个条件启用了中断并且发生了该中断，则在I/O中断块逻辑执行期间也会设置该条件的诊断位。下一次PLC输入扫描总是将此中断状态位清除回0，因为诊断报告已禁用。10.3.14模块数据：ALG004和ALG008模块从其配置的输出字接收其信道数据，从其分配的信道值参考地址开始。每个信道占用两个字（无论是否使用信道）：PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月模拟输出模块464信道值参考地址包含此输入+0、1信道1+2、3信道2+4、5信道3+6、7信道4仅适用于模块IC695ALG708：+8、9信道5+10、11信道6+12、13信道7+14、，15信道8根据其配置的信道值格式，每个启用的信道输出参考位置被读取为32位浮点或16位整数值。在16位整数模式中，32位通道数据区的低位字包含16位整数通道值。32位中的高位字（高位16位）被忽略。16位整数的完整范围是从+32767到-32768的有符号十进制值。因为通道参考位置是32位，所以应用程序可以将32位带符号的十进制值写入输出参考。但是，程序逻辑必须将值的大小限制在+32767到-32768的范围内。超过此范围将导致符号位的错误解释和输出通道操作错误。10.3.14.1信道诊断数据：ALG704和ALG708除了来自现场设备的输入数据外，模块可配置为向CPU报告信道诊断状态数据。CPU将该数据存储在为该模块配置的诊断参考地址中。此功能的使用是可选的。每个通道的诊断数据占2个字（无论是否使用该通道）：诊断参考地址包含以下诊断数据：+0，1通道1 PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月模拟输出模块465+2，3通道2+4，5通道3+6，7通道4仅用于模块IC695ALG708：+8，9通道5+10，11通道6+12，13通道7+14，15通道8当诊断位等于1时，通道上出现报警或故障状态。当位等于0时，报警或故障条件不存在，或者该通道的配置中未启用检测。对于每个通道，该数据的格式为：10.3.14.2模块状态数据：ALG704和ALG708。模块还可以可选地配置为向CPU返回4位模块状态数据。CPU将此数据存储在为该模块配置的32位模块状态数据参考区域中。PACSystems*RX3i系统手册第12节GFK-2314T 2019年9月模拟输出模块466 PACSystems*RX3i系统说明书第12节GFK-2314T2019年9月份模拟输出模块467端子
An I/O Interrupt block should be triggered if a High Alarm condition occurs on channel 2. ▪ Configure the High-Alarm condition. ▪ Set the High-Alarm Interrupt Enable flag for Channel 2 in the module configuration. The reference address of Channel 2 corresponds to %AQ00003 (2 Words per channel), so the interrupt program block Scheduling properties should be set for the "I/O Interrupt" Type and "%AQ0003" as the Trigger. Fault Reporting and Interrupts These modules have separate enable/disable options for Diagnostic Reporting and Interrupts. Normally, disabling a diagnostic (such as Low/High Alarm or Over/Under range) in the configuration means that its diagnostic bit is never set. However, if interrupts are enabled for a condition and that interrupt occurs, the diagnostic bit for that condition is also set during the I/O Interrupt block logic execution. The next PLC input scan always clears this interrupt status bit back to 0, because Diagnostic Reporting has it disabled. 10.3.14 Module Data: ALG704 and ALG708 The module receives its channel data from its configured output words, beginning at its assigned Channel Value Reference Address. Each channel occupies two words (whether the channel is used or not): PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 464 Channel Value Reference Address Contains this Input +0, 1 Channel 1 +2, 3 Channel 2 +4, 5 Channel 3 +6, 7 Channel 4 For Module IC695ALG708 Only: +8, 9 Channel 5 +10, 11 Channel 6 +12, 13 Channel 7 +14, 15 Channel 8 Depending on its configured Channel Value Format, each enabled channel output reference location is read as a 32-bit floating-point or 16-bit integer value. In the 16-bit integer mode, low word of the 32-bit channel data area contains the 16-bit integer channel value. The high word (upper 16-bits) of the 32-bits is ignored. The full range of the 16-bit integer is a signed decimal value from +32767 to –32768. Because the channel reference location is 32 bits, it is possible for the application program to write 32-bit signed decimal values to the output reference. However, the program logic must restrict the magnitude of the value to the range +32767 to –32768. Exceeding this range will result in misinterpretation of the sign bit, and incorrect output channel operation. 10.3.14.1 Channel Diagnostic Data: ALG704 and ALG708 In addition to the input data from field devices, the module can be configured to report channel diagnostics status data to the CPU. The CPU stores this data at the Diagnostic Reference Address configured for this module. Use of this feature is optional. The diagnostics data each channel occupies 2 words (whether the channel is used or not): Diagnostic Reference Address Contains Diagnostics Data for: +0, 1 Channel 1 PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 465 +2, 3 Channel 2 +4, 5 Channel 3 +6, 7 Channel 4 For Module IC695ALG708 Only: +8, 9 Channel 5 +10, 11 Channel 6 +12, 13 Channel 7 +14, 15 Channel 8 When a diagnostic bit equals 1, the alarm or fault condition is present on the channel. When a bit equals 0 the alarm or fault condition is either not present or detection is not enabled in the configuration for that channel. For each channel, the format of this data is: 10.3.14.2 Module Status Data: ALG704 and ALG708 The module can also optionally be configured to return 4 bits of module status data to the CPU. The CPU stores this data in the 32-bit Module Status Data reference area configured for this module.
