Aug 27, 2010 We run PCo 2.0.1.8 with multiple agents (OPC-DA 2.05a - MII 12.1.6.Build(91)).Sometimes our MII-Server is under heavy load and is not able to process PCo messages anymore. Therefore one PCo agent stops working and logs this message:'System is too busy. Hola, no quiero hacerles perder mas tiempo de lo que me van a dar asi que sere claro: tengo un OPC que creo que es OPC DA 2.05a de MATRIKON, que nunca he usado o tratado antes. 1-Como saber el protocolo de OPC que utilizo? 2-Si es compatible con TIS (TECHNICAL INFORMATION SYSTEMS) 5256.
