ARC=xxx To many Events! (ARCL=yyy/h)
STAP TYP 00:00:00 NAME
ARC=xxx To many Events! (ARCL=yyy/h)
->DEVINI (M.ARCL)
The meaning of this message is dependent on the TYPE:
For TYPE=LS,DI,AI,MX,OZ,PLT,RGB,DO,AO,VIP,CI this message means that, since
the last hour change, a larger number of data packages than specified in $S,ARCL=yyy
have been received from the process station, namely xxx. Because there is a danger
that the VISONIK server could be overloaded, the system automatically sets OSV=YES
and also tags the point with STAP=?OA, which means: "OSV due to ARC".
When TYPE=PS,BLN,OS, the message has the same meaning as above, but the effect
is less drastic: The point is only tagged with STAP=!AC.
When TYPE=TY, the message means that, since the last hour change, a greater
number of terminal initialisations have taken place than the number specified in
$S,ARCL.
When TYPE=SY, the message means that, since the last hour change, SHST has
changed a greater number of times than that specified in $S,ARCL and indicates
problems with shadow operation.
When TYPE=RI, the message means that, since the last hour change, the RIST
parameter has changed a greater number of times than that specified in $S,ARCL. This
message indicates a ring problem, e.g., ongoing changes between "Normal" and
"Normal with noise" states.
The cause must be rectified. Additionally, OSV must be manually set to "NO" for
TYPE=LS,DI,AI,MX,OZ,PLT,RGB,DO,AO,VIP,CI.
