I write a user-written model, specifically a CCT type user-written model. dyr data is like：

6 'USRBRN' 9 '2 ' 'MESBRN' 301 2 0 0 0 20 /

And the Fortran code is like：

subroutine mesbrn(km, islot)
......
    return
end subroutine

When I load the dll and run the simulation, there is always a message saying:

 CCT TYPE USER DEFINED MODEL "
 TO BUS      9 [BUS__6__    230.00] CKT 2  NOT ACCESSIBLE

CAN SOMEONE HELP ME TO SOLVE THE PROBLEM. THANKS.
