如果通道2出現高報警條件，應觸發I/O中斷塊。? 配置高報警條件。? 在模塊配置中設置通道2的高報警中斷啟用標志。通道2的參考地址對應于%AQ00003（每個通道2個字），因此應為“I/O中斷”類型設置中斷程序塊調度屬性，并將“%AQ0003”設置為觸發器。故障報告和中斷這些模塊具有診斷報告和中斷的單獨啟用/禁用選項。通常，禁用配置中的診斷（如低/高報警或過高/過低范圍）意味著其診斷位從未設置。但是，如果為某個條件啟用了中斷并且發生了該中斷，則在I/O中斷塊邏輯執行期間也會設置該條件的診斷位。下一次PLC輸入掃描總是將此中斷狀態位清除回0，因為診斷報告已禁用。10.3.14模塊數據：ALG004和ALG008模塊從其配置的輸出字接收其信道數據，從其分配的信道值參考地址開始。每個信道占用兩個字（無論是否使用信道）：PACSystems*RX3i系統手冊第12節GFK-2314T 2019年9月模擬輸出模塊464信道值參考地址包含此輸入+0、1信道1+2、3信道2+4、5信道3+6、7信道4僅適用于模塊IC695ALG708：+8、9信道5+10、11信道6+12、13信道7+14、，15信道8根據其配置的信道值格式，每個啟用的信道輸出參考位置被讀取為32位浮點或16位整數值。在16位整數模式中，32位通道數據區的低位字包含16位整數通道值。32位中的高位字（高位16位）被忽略。16位整數的完整范圍是從+32767到-32768的有符號十進制值。因為通道參考位置是32位，所以應用程序可以將32位帶符號的十進制值寫入輸出參考。但是，程序邏輯必須將值的大小限制在+32767到-32768的范圍內。超過此范圍將導致符號位的錯誤解釋和輸出通道操作錯誤。10.3.14.1信道診斷數據：ALG704和ALG708除了來自現場設備的輸入數據外，模塊可配置為向CPU報告信道診斷狀態數據。CPU將該數據存儲在為該模塊配置的診斷參考地址中。此功能的使用是可選的。每個通道的診斷數據占2個字（無論是否使用該通道）：診斷參考地址包含以下診斷數據：+0，1通道1 PACSystems*RX3i系統手冊第12節GFK-2314T 2019年9月模擬輸出模塊465+2，3通道2+4，5通道3+6，7通道4僅用于模塊IC695ALG708：+8，9通道5+10，11通道6+12，13通道7+14，15通道8當診斷位等于1時，通道上出現報警或故障狀態。當位等于0時，報警或故障條件不存在，或者該通道的配置中未啟用檢測。對于每個通道，該數據的格式為：10.3.14.2模塊狀態數據：ALG704和ALG708。模塊還可以可選地配置為向CPU返回4位模塊狀態數據。CPU將此數據存儲在為該模塊配置的32位模塊狀態數據參考區域中。PACSystems*RX3i系統手冊第12節GFK-2314T 2019年9月模擬輸出模塊466 PACSystems*RX3i系統說明書第12節GFK-2314T2019年9月份模擬輸出模塊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.
