Dear All members
I have problem about CPU CompactLogix 1769-L31 as follows;
Step 1. I connect this CPU 1769-L31 with 1769-PA2 and 1769-ECR.
Step 2. Later, I power ON to 1769-PA2
But The green LED near the lamp symbol (LED Power)
on 1769-PA2 will turn OFF immediately !
1769-PA2 Not working !!
Step 3. Later, I change the another CPU to connect with this 1769-PA2
The 1769-PA2 still working properly.
I suppose that there is the problem in 1769-L31, but I don't know
what is a problem ? and solution ?
anyone please tell me how to fix this problem.
Thank all
