在项目用的是PCS7系统,系统有417H和414FH二个站组成。417H的CPU状态灯我参考西门子的技术文档已经做好,但414FH的CPU状态灯做法和417H一样吗?我是第一次用F系统对它还不太了解,请高手指点。谢谢!
问题补充:
我用的是SFC51块,而你给的技术资料是FB523 (H_STATUS),二者有啥区别?
最佳答案
1、FH系统CPU的状态灯读取和普通CPU一样吗?
一样。如果CPU S7-414H or S7-417H采用了故障安全软件包( S7-F Systems software package),即为CPU S7-414FH or S7-417FH.
A failsafe, redundant SIMATIC system is based upon a standard CPU S7-414H or S7-417H. For use as failsafe controller, the user can expand the standard CPU to include safety-relevant functions with the S7-F Systems software package. This makes it possible to implement safetyrelevant and redundant tasks inexpensively using the same components.
