如何解决:由I/O引起的STOP模式
图片说明: 1,故障图片
***佳答案
1、如何解决:由I/O引起的STOP模式?
这个问题要认真检查与I/O相关的所有之处,例如模板的安装、电源、接线及现场干扰等。如果故障原因不排斥,只通过添加OB121和OB122使之不停机,这种带故障运行方法是不安全的。必须要仔细进行论证、评估带这种故障继续运行会有什么后果。如确认是安全的才能添加OB121和OB122使之不停机。
2、Stop caused by i/o error:
上述诊断信息表明为I/O错误 user (z1): 941a
no relevance for user (z2): 000f (z3):44ab
上述诊断信息表明为I/O错误。
2、可能的原因:
转帖:
、S7-300:
A module was removed or inserted illegally.模板被拆除或安装有问题。
、 S7-400:
Failure of the module inserted/removed monitoring or error in interrupt servicing due to a defective module or due to removing or inserting a module illegally.
To correct or ***oid errors:
Based on the system status lists, check the current I/O configuration detected by the CPU. Compare this with the existing configuration to see whether there are any defective modules.
· Bus error in the local or distributed I/O
To correct or ***oid error:
To remove the error, you must switch the device off and then on again. If the error still occurs, check the bus connection and interface modules in the distributed I/O. Make a note of the HEX code marked as "Not user-relevant" in the detailed information for the diagnostic buffer entry and contact your manufacturer.
· This error can occur when an expansion device is switched off, for example, if an IM module is defective.
To Correct or ***oid Error:
Replace the defective module.
.STEP.7.Professional.v12中如何调用FC105 106以及其他功能块???
***佳答案
在基本指令-转换操作:SCALE和UNSCALE,作用与FC105,FC106一样
set A I 0.1
s***e s***e
beu beu
首先请问这两者有什么不同?然后 beu不是无条件结束吗? 为什么这里 前面还有A I 0.1呢,这是条件吧,是不是这要 I0.1只要就这个块就结束?那么如果这个块被调用的话 后面的EN0就有输出吗?
***佳答案
1、
A I 0.1
s***e //将RLO的结果存入BR中。
beu //无条件结束
2、如果上述A I 0.1指令的II 0.1为1,即RLO的结果为1,则如下述指令功能相同;如果上述A I 0.1指令的II 0.1为0,则如下述指令功能不同:
set // 将RLO置为1
s***e //将RLO的结果存入BR中,即RLO=1。
beu////无条件结束
3、后面的EN0就有输出吗?
如2、中的程序后面的EN0就有输出。如在1、中当A I 0.1指令的II 0.1为1时后面的EN0就有输出。
