mkc Posted November 21, 2016 Report Share Posted November 21, 2016 Hello Is it possible to read one PLC (V130 in my case) with more than one UniOPC server software which are running in different computers? I have an application where V130 is read from one PC by UniOPC server and I need read same PLC with other UniOPC server located in other PC. All tags are identical. I installed UniOPC program to both PC and they both can read the PLC but not simultaneously. I can connect both UniOPC with PLC, but only firstly connected OPC can read tag values. Secondly connected OPC tags quality is //Uncertain, non-specific// and tag values are zeros. Both UniOPC sever have identical configuration. Is it in principle not possible to read one PLC with two UniOPC or I have problems with settings? Regards, Meelis Quote Link to comment Share on other sites More sharing options...
