Re: [foxboro] OPC & SSC

Hello Pat,

there is a special OPC-Server called "I/A-Connect" from Invensys Germany =
that  supports SSC. It=C2=B4s for installation on AW70 only (NT4/XP/Serve=
r 2003) and runs with I/A Versions 6.1-8.2. It=C2=B4s directly based on O=

    Betreff: [foxboro] OPC & SSC
   =20
    Hi all,
    =20
   =20
    Anybody out there who has used Supervisory Setpoint Control by means =
of OPC?
   =20
    =20
   =20
    We use the DMCbridge which works great with SSC but now need to imple=
ment an
    other application which needs to talk to I/A through OPC. I was hopin=
g we
    could used the standard SSC methods.
   =20
    Is there any documentation available (apart from the SSC B0193RY manu=
al)
    which specifically addresses the OPC/SSC combination?
   =20
    =20
   =20
    I am completely new to OPC so I don't know what it can/cannot do?
   =20
    =20
   =20
    For SSC you need to be able to set/read the status bits (.LHI, .LHO, =
=2EINITC,
    .ACK etc) in/from parameters like .BLKSTA, .SUPBCO, .SUP_IN.
   =20
    Also 'single shot write' to the .SE parameter should be possible.
   =20
    =20
   =20
    Can you do all of these things with OPC ?
   =20
    =20
   =20
    Another related question:
   =20
    The SSC 'control group' 'span' is limited to the CP it is configured =
in,
    right?
   =20
    You would need to 'cascade' the control group by linking if you would=
 want
    the control group to 'span' multiple CP's, right?
   =20
    Example: I could have 2 individual applications both using control gr=
oup 1
    as long as all control blocks for applic. 1 are in CP1 and all contro=
l
    blocks for applic. 2 are in CP2?
   =20
    We've used up all 8 control groups already but this new application w=
ill be
    dealing with completely new CP's.=20
   =20

    Thanks in advance for your, highly appreciated,  feedback.
