一、2.1 Error numbers (ACCU 3 high byte, DB 1 DW 160)
General The error number FEHLCODE gives a detailed coding of the cause of error.
The error numbers are hexadecimal and therefore correspond to the representation
in the function:
AUSGABE ADR:AG,F0000
with which FEHLCODE and the additional error information can be read.
The error numbers and the additional information are also stored in the diagnostics
DB (DB 1) DW 160–164.
If the PLC goes into the stop state with an error number identified by a W, a warm
restart will be effected after the next RESET (unless cold restart or installation has
been selected.
All other error numbers cause a cold restart.
If no error has occurred the error number is 00.
这段话里：FEHLCODE；If the PLC goes into the stop state with an error number identified by a W, a warm
restart will be effected after the next RESET (unless cold restart or installation has
been selected.代表什么意思
二、报警号W7C是什么意思；并且007C 0100 0000 0000 0000这个报警号是什么东东
最佳答案
General The error number FEHLCODE gives a detailed coding of the cause of error.
一般错误号fehlcode给出了一个详细的编码错误原因
If the PLC goes into the stop state with an error number identified by a W, a warm
restart will be effected after the next RESET (unless cold restart or installation has
been selected.
如果PLC进入停止状态，确定由W，一个热启动引起的错误
重新启动后生效的下一个RESET（除非冷启动或安装
被选中）
不知道翻译的对不对。
