OPCServer1. OPCGroups. DefaultGroupUpdateRate:=500; Internet is just like that, but here I compile pass, is read-only property , strange that is wrong, but looked through online shopping, no one said no!

DefaultGroupUpdateRate, update cycle, the default initial value is 1000 milliseconds, it have to be set before the OPCGroups activate the connection,

thank you for your reply, I wrote, so the problem is compiled through, however, prompt the read-only,
OPCServer1. Connect1 (' S7200. OPCServer ', 'MyComputer');
OPCServer1. OPCGroups. DefaultGroupUpdateRate:=500;//this compilation pass, prompt read-only,
Group:=OPCServer1. OPCGroups. Add (' MyGroup);
