错误代码将保留，直到您发送E2 COMMREQ清除错误代码或重新配置模块。12 12-16系列90–30 PLC I/O模块规格–2000年7月GFK–0898F仅报告近的错误；如果发生另一个错误，现有的错误代码将被覆盖。错误的优先级是：1。COMMREQ函数（高优先级）2无效。无效频道。3.无效数据（斜坡或报警参数）（低优先级）。因此，如果存在多个错误条件，则在错误代码中报告具有高优先级的错误条件。第二个八个位置-（可用于%I SIZE值16、24）%I位置描述%I+8输入：通道#1报警LO-0指示值高于极限；1低于或=%I+9输入通道#1报警高-0指示值低于限值；1高于或=%I+10输入通道#2报警LO-0指示值高于限值；1低于或=%I+11输入通道#2报警高-0指示值低于限值；1高于或=%I+12输入通道3报警LO-0指示值高于限值；低于1或=%I+13输入通道3报警高-0指示值The error code will remain until you send an E2 COMMREQ to clear the error code or reconfigure the module. 12 12-16 Series 90–30 PLC I/O Module Specifications – July 2000 GFK–0898F Only the most recent error will be reported; an existing error code will be overwritten if another error occurs. The priorities for errors are: 1. Invalid COMMREQ function (highest priority) 2. Invalid channel. 3. Invalid data (ramp or alarm parameter) (lowest priority). Thus, if multiple error conditions exist, the one with the highest priority is reported in the error code.
