We have AB Make PLC System for our Boiler Compact Logix CPU. It has a AENT1734 Module. After one Yr. of Installation of this system we are facing Problem in above mentioned Module. It's last red Indication Starts Blinking CPU remain in healthy condition. But due to no communication Between I/O cards & CPU, Operator Station gets Hanged Up. i.e. Operator can not perform any operations. We Reset the Power supply of the system, wait for few mins & then restart the system. Boiler gets shutdown for this period (Production Loss). Initially we found that Its temperature was rising high. We provided External cooling Fan for It. the frequency of this fault reduces from 10 Hrs to 1 month, but still this card some time goes in Fault mode & trips the plant.
Pl. help us in understanding & solving this problem. As mentioned temperature rise was one of the problem & we avoided the same. Temperature Now is Normal & is @ 25 °C.
