Wonderware Intouch system version 5.6B is linked to 24 sets of Siemens PLC-115 having CP-143 communication processor. H1 communication via Intel's PCLink2A card(also known as PCL2NIA)is connected to a PC running on windows 3.11. we have 2 identical system. In one system PCL2NIA card is failed and system is down. Intel informs that this card is no more produced. I am seeking for either equivalent card for PCL2NIA or an address to obtain this card.
