  Third-party software? (ABB Procontrol) 
 The Question is:
 
Hello, How are you ?
 
We have many servers of digital such as VAX 4000/60, 90, 90A  with Open VMS
(6.1) and many Alpha  Stations 2004/100 with digital Unix 4.1.  I have faced
certain typical problems and I would like to get clarify from your expert
advisor.
 
We use these servers for the process control as MMI with POS 30 of ABB
Procontrol system.  We connect  servers to Procontrol system via TS50
module. Which communicates with the server by CPS.
 
Q1. When I started the server (VAX 4000/90) it started and established
communication with TS50 (status code is 6, which defines  TS50 is OK) and
loaded with complete configuration and mimic files and ready for operation
(status code of TS50 is 9, which de
fines that server is ready for operator interaction).  It worked for some
time initially, (say 15 minutes) all of sudden it looses communication with
TS50 (i.e the status on TS50 is 6).  And some times it is observed that TS50
got initiated from  '0' to '
6'.  Changed Transceiver (DECXMA) also, once 'STAPBS' is also initiated.
Now it is observed that it changed its status from '9' to '6' after 2 hours.
(i.e after starting the server again)  PBS30.log shows that it has no  SYK
file in PBS30_DBDATA.DAT, but
 when opened that specific directory, the same file exists.  What can be the
reason ? How to solve the problem ?
 
Q2.  During the lose of communication with the server, the mimic will freeze
and no chance of restarting the server, because remote login (through
'telnet') is not allowing to get into the server ( operating system is not
started to login).  Is there any
procedure to start the server other than switching off and on power supply
to the server.
 
Q3. How to start PIA process if  'STAPIA' command does not work?  ' STAICO'
starts another icon..  Why 'STAPIA' does not work ?
 
Q4.  If the screen freezes will CTRL + F2 work, if not so any other commands
to release the screen, or no way to restart the computer from 'session
manager' ?
 
 
 
 The Answer is:
 
  You will need to contact the software vendor (ABB?) for assistance,
  these questions do not involve software that the OpenVMS Wizard is
  familiar with.
