Hi all
I tried to find answer in the previous theads but did not, my problem that my input card analog 1756-8channels for AB logix 5550 configured it to 4-20ma and connected the channels to ma source as simulator using only 4 channels differential as it was in the manual but can not get any value changing in the channels data ,and some of them already reads some data even if its not connected.
any help will be appreciated
