Did you mean: 

micrologix 1400 was blocked !

Hello,

 

In our project we use the micrologix 1400, some times the micrologix blocked to acquire the value of Dpressure in our process!!

By reboot of PLC the problem resolved.

 

What's the problem!!

 

thanks for advice.

Hi,

 

It's not clear what you mean by being blocked.

Do you have any specific steps to reproduce the error? And how did you use NI EIP toolkit in the communication?

 

You may check if you have any network problem on yoru side. If you are using router, you may try if changing it to a switch can cure the problem, etc.

Hello,

 

we have a small application commanded with micrologix 1400, the application is; the differential transmitter of pressure transducing the instantaneous value of pressure on piping to the PLC(logic input), and when the pressure exceed 150 mbar the PLC execute one cycle to clean filter.., the problem is, some times the PLC blocked to read the value of pressure(we are sure that the input is blocked on PLC).

 

for exemple the value on the terminal of PLC blocked on 80 mbar, and not fixed on the panel view of transmitter.

 

thanks!

Do you have any EIP VI running in this setup?

How do I reproduce it?

Hi Ali,

 

I meant the NI Industrial Communication EtherNet/IP toolkit.

hello,

no NI Industrial Communication EtherNet/IP toolkit running
no relation between this problem & memory(RAM) of PLC!
