Landis & Staefa Division Function STAT 2-303
2.30 STAT Statistic Register
The Statistic Register is a reserved area in disk memory for depositing any messages
from the VISONIK system. This Register's capacity is variable and is sufficient to store
specified events, either from the external plant equipment or from VISONIK itself, for a
relatively long period.
The system is advised in advance which events are to be kept for statistics. From this
moment on, access to statistics data can be made at any time and the dialogue
terminated with Ctrl/E as required.
A condition for the optimum utilization of Register capacity is a suitable choice of
terminal device masks. The Statistic Register is handled in a similar way to an output
terminal. Message types, which can be directed to specified output terminals and
similarly to the Statistics Register, are defined using the parameters shown below.
For each message type which should be deposited in the Statistic Register the
associated parameter in system point $SY should be extended with option "+=STAT":
DEVINI for initial $SY message after system BOOT or for error messages
DEVPCH for messages on manual (keyboard) parameter changes using
Function PNT or PNX.
DEVLOG for acceptance messages.
DMMx (DEVPX..DMM3) for point messages including their message priorities
MSGP=0..3.
MMxx (MM00..MM15) for Reaction messages
