Report Control Blocks problem
Hi,<br><br>I am sending some variables with a device via IEC 61850 MMS communication. When the data is sent from the IED's data model and without the use of RCBs, zenon client driver can receive the variables and read them. However, when I send the same data by RCBs with the same type of communication, zenon client driver does not receive anything and the query window just freezes.<br><img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAbsAAABvCAYAAAB 1sW6TAAALq0lEQVR4Ae3dT27qvB6HcUZ3J3cF7KabYR3MOkdHu gtgwga6hEqdnGF1dpArB5w4CYRA+VN++bwSCoTEib9+6sd20/MuKv9JQAISkIAEgiewCF4/1ZOABCQgAQlUZAcCCUhAAhIInwDZhW9iFZSABCQgAbLDgAQkIA EJhE+A7MI3sQpKQAISkADZYUACEpCABMInQHbhm1gFJSABCUiA 7DAgAQlIQALhEyC78E2sghKQgAQkMFl23x+bar1et6/t5+PT+/6oNutN9fH9+EsfveIT76duj14b1Ps2H9Ugnife59HcbrXzpvX6 rLYHtj6362rzayC7VVjKkcC8E5gku73otlWpt9QhrHud7byjfG DtUyc/kFrqrNfVerC/f19tp97/Zt6fy1y+q4/NLxpUzbth1F4CN0ngvOzq0XNXdPsr6xBu0gJXFJIGH/2ZR9q3/Tgmwf4Fyk69/92cP/dy+dwazM0ZB3UPl8B52Y380LfLPb2Ooup9roWZl0CzOPfHbLdp eXRTbTbrqjNRTNcdzFLKcpNsc5m9c+tmKstP1yzPTQeUnw/vP7bNMm0rkwnf1euGY8dVVVVksPn4aJbMLifqyCAjlZ3CS9tBZ mVd0z22mTUz8+Le1utu+3x8pqXj/Tn7S7TL2W1Gl7ZFN4/2muleT5Q1do/f+3NO8nP03O49DNrkZJaXt5gzJCCB5ydwVnb1EmanF2lvup1hH Dr65pdF5efyfXLM9jAr2Xe8TYfZk2oS6fCyRVm949u7yu965Xf klo4pyqrfF8uyqexOpz/2XV7u2l+vEciRMnJ96kyv/t1juk4WUqpHIb+THXS/rvme+zkM26cZcNT1KX6XVdYvvc+Vy/F3tvtsmrbuZF9ecy+t9rhcSHn/5fHF/t49tPwUx9TV7fKXb3vYJum8Mud8L7YSkMArJnBWdklOpzqySbL rjKoPs4q6h+l1QnUHmDuXz2o7OkNpR+XDjjE3w7HyT3XyY8dO/W7kuIGE+sfme56yTefmnNJkrljSHFwnl1der3zf5jh8+Kh3XF9 Q5edDG09ui1NM1PvbuuW7L2fFzX0OGCpzKfgZu1aHsX59i0FEc yPeSEACr5rAedmd6oDKGUXZ8dVJFB3HyfOLYw7p5Y47b4ehHj8 ndYB5hN6e0z927PMtvhspI2Uw2rG2d33+XbpOFkJ6XyxL5veda 6USy3sr32fZ5fLKq/eO65TRL3N/Xmq3SW1xiolL9/fuKXOTt/VdjZXZyelYfY/lUmbkvQQk8CoJnJddvWrUf8pvv9zUzvj2nxvh1EtceRaVOpFi+ atJpt+5HDrezbbannwS7sg59WnF7OZk+efuMd9vKqC8Tvl+7Lt zx7VC3kshX68879T7plKptqefFBxINZ83Vm76bkr7lGX0c8jX6 c00m93Hzj12zX0bDWeIE++xrn/ip5TU2Lmn2iSzeOTPOJo6eSMBCbxSApNklyqUR+3NMlL/d0614PIy5bb7AEY9ui5mIIMlqDay8T9pKDrN8nrNTKctpyusw/7ynG15j0W59aHl5/J9+rL8fOp9/7h6xFA8/FI+oHKqjHL/4f4Pm87MpfxqkuzSr01zOx3+mGRS+/Tvp/hc5jq1LY5eM+fWstIMoI4eX9xDncNelu0grAmsecim5jcXWtz3 4AGV9F0+rszYewlI4CUTmCy7Qe2azifPUAZHXLWjfbDgqtNf46 Q6u3L2ceFtp/M7S3AXnu/wMwmMzJ7PnOlrCUjgdyZwvezuUZ+ZdOL1zOqHsqpn2mYe96BwP/OV7V2yVagEnpXAL5HdYfmpvzT6rFRuft1cv7w894NZ3c3vTYES kIAE4ifwS2QXP2g1lIAEJCCB5yVAds/L3pUlIAEJSOBBCZDdg4J2GQlIQAISeF4CZPe87F1ZAhKQgAQel ADZPShol5GABCQggeclQHbPy96VJSABCUjgQQmQ3YOCdhkJSEA CEnheAmT3vOxdWQISkIAEHpTA4t+/f5WXDDCAAQxgIDIDZEf2BjsYwAAGwjNAdiAPD3nk0aq6mY1hYB oDZEd2ZIcBDGAgPANkB/LwkBv5Thv5yklOkRkgO7IjOwxgAAPhGSA7kIeHPPJoVd3MxjAw jQGyIzuywwAGMBCeAbIDeXjIjXynjXzlJKfIDJAd2ZEdBjCAgf AMkB3Iw0MeebSqbmZjGJjGANmRHdlhAAMYCM8A2YE8PORGvtNG vnKSU2QGLpbddrutvGSAAQxgAAPPZuASOV8su//877/VT19///6tvGSAAQxgAAPXMpBES3ZkajCBAQxgIDQDZAfw0IBfOwp0nhkE BmIxQHZkR3YYwAAGwjNAdiAPD7kReqwRuvbUntcwQHZkR3YYwA AGwjNAdiAPD/k1o0DnmD1gIBYDZEd2ZIcBDGAgPANkB/LwkBuhxxqha0/teQ0DZEd2ZIcBDGAgPANkB/LwkF8zCnSO2QMGYjFAdmRHdhjAAAbCM0B2IA8PuRF6rBG69tSe 1zBAdmRHdhjAAAbCM0B2IA8P+TWjQOeYPWAgFgNkR3ZkhwEMYC A8A2QH8vCQG6HHGqFrT+15DQNkR3ZkhwEMYCA8A3eXXbqAlwww gAEMYODZDNz1/1R+SeGO/XfR/zZeXvLCAAYwcB8GFoK9T7BylSsGMICB38MA2f37PY3hB0NbYAA DGLgPA2RHdpZaMYABDIRngOxAHh5yI+X7jJTlKtdXYoDsyI7sM IABDIRngOxAHh7yVxp9ulezJQzchwGyIzuywwAGMBCeAbIDeXj IjZTvM1KWq1xfiQGyIzuywwAGMBCeAbIDeXjIX2n06V7NljBwH wbIjuzIDgMYwEB4BsgO5OEhN1K+z0hZrnJ9JQbIjuzIDgMYwEB 4BsgO5OEhz6PPP3/+VF7TM8i52ZrBRWCA7MhuVrL7+vqqvM5nkAYFETo4dSDqzADZk d1sOrXUgRPdedGljMiOJLIkomzJjuzIzmxvMAggO7KLIrlcD7I jO7IjO7LTD4TvB8gO5OEhzyM7y5jTljAtY5rV5Z+ZSFuyIzuyM 7Mzs9MPhO8HyA7k4SHPo9N7zex2q7dquVhUi/RaLqu3991AHjd/MGa3qpbLVbW7k6j9zs7sLv/cRNmSHdmR3Q+EsVstq8VyVb3vDkuEu/fqbbGsVvnzD8oeFSTZzYbbKLJ5dj3Ijuxm02ncfma3q1bLB4jt mDDJbjbcPlsSUa5PdmQ3m07j5rI7J5z3YnlzkZY3v6qv+py3av W23C975v1JaGlWuDwsh9b7D8uhu1W7f/m2nzWeu/YxQV6wzzKmZcwoksv1IDuyI7sLJNBZWrxEOPnYtC1FloRY/+4tzRIX1dsqCy4vh/Zmj2U5fmc3G3Zzh217/SCE7MhuNh3Gw2d29Ywsz+DSwyurapdllQWbP+dt3p+3aX9++KX ZLqvVuwdUdPzXd/xzzI7syI7sslgu3vZmXZ3zDzOz/GRmllne5mPz57zN+/M27V+8Ve/5c96eOj5//8OtZUwiiSZEsiM7svuBGE4/jZlkd/j92tdXlf48YXRm9zW2jFkubx5mdGQ3G26jSedZ9SE7sptNp3Hz ZcyDJDt/Z1f8Pq7cv1zu/0Th5DJmKuvkAyrFgyseUJkNr8+SQtTrkh3ZzabzuJfsOg+t/GCW+JvKsYxpGTOa9MiO7MguiKBuKUuyIzuyI4fZyCEa7GZ2/iHoaEyrz/RBiZkdec9G3mRHduQwXQ7RsiI7siM7y5iDf7jaMuZ8pRBNcrk+ ZEd2ZEd2ZKcfCN8PkB3Iw0OeR3aWMS1jZhZs5zdzJTuym5Xskv C8pmVACPMTQuQ2Jzuym43sIv8gqxsxYWCcAbIjO7LDAAYwEJ4B sgN5eMiNeMdHvPKRzxwYIDuyIzsMYAAD4RkgO5CHh3wOo1Z1ND vDwDgDZEd2ZIcBDGAgPANkB/LwkBvxjo945SOfOTBAdmRHdhjAAAbCM0B2IA8P+RxGrepodoaB cQbIjuzIDgMYwEB4Bv4P3gGFWqE7N0QAAAAASUVORK5CYII=" alt=""><br><br>Any ideas on why it freezes like this and how I can resolve this situation?

Re: Report Control Blocks problem
The screenshot looks like in zenon Editor query running during the driver online imports variable definitions; or maybe during the browsing the description of available RCBs in the driver configuration dialog. <br><br>I suppose the issue is: when IED is configured with a SCL file where there is no Report Control Blocks then this IED supports the MMS association and the data model browsing correctly. When the IED is configured with a SCL file where there are some RCBs defined, then the IED behaves no more standard compliant and stops to communicate after 4th request; IED hangs or responds with malformed MMS frames, but keeps the TCP socket open.<br><br>I would contact the manufacturer of the IED. Maybe the changes in SCL file are not correct (syntax, quantities etc.). Or the enhanced SCL not suitable according the IED's capacities. But a correct IED shall refuse the update with an invalid SCL file or containing not supported capabilities. <br><br> If you can record a sniff with Wireshark then you can contact your local COPA-DATA Support officially and ask for the favor to diagnose the IED basing on this Wireshark sniff and SCL file. Maybe we will be able to advise you how to workaround this issue in IED. The zenon 7.20 is already old version, and in the newest zenon version the iec850 driver has (internally) some additional features improving handling against IEDs which are not fully IEC 61850 standard compliant; try out.<br><br>zenon versions Support Cycle: <a href="https://www.copadata.com/en/support-services/release-support-cycles/" data-cke-saved-href="https://www.copadata.com/en/support-services/release-support-cycles/">https://www.copadata.com/en/support-services/release-support-cycles/</a><br><br><br><br><br><br>
