ACCON-OPC-Server UA for Siemens S7-300, S7-400, S7-1200, S7-1500, 840D sl, 840D pl, 810D pl, ONE

ACCON-OPC-Server UA is a reliable, easy to use OPC UA Server for Siemens SIMATIC® PLCs S7-300, S7-400, S7-1200, S7-1500 or compatible PLCs and SINUMERIK® 840D sl, 840D pl, 810D pl, ONE and Create MyVirtual Machine. We place particular emphasis on high performance data access and low set up time.

Safety is a top priority. It supports all UA security levels. The user can authenticate with his username and password or a certificate. If the server certificate expires, you will be automatically notified by e-mail.

The ACCON-OPC-Server UA combines highest performance with the possibilities of retrofitting. Old controller types can still be used with OPC UA. You can access the PLC via TCP/IP, or a suitable communication adapter, e.g. the ACCON-NetLink-PRO compact.
