I have AllenBradley PLCs on Ethernet. I have RSLinx OEM installed on my server. I want all my clients to be able to access data (The clients do not have RsLinx). What are my alternatives? Can I use the RSLinx OPC server to serve the remote clients which do not have rslinx? or Do I need to write my own OPC server which is capable of serving remote clients and talks to Rslinx to get the data?
