Re: [foxboro] Telemetry

The MDI is a Foxboro product. 

You need the DI-30 hardware and software license plus the Modbus Master or
Modbus Slave software.

I am not sure of the correct part numbers, but your Foxboro Account
Representative can get them or either of you can check the I/A Store
(www.iastore.com <http://www.iastore.com> ). 

To see the software for the "Modbus Master" or "Master Slave" use the
keywords "Modbus Master" or "Modbus Slave"

        Alex, is the MDI a Foxboro product ? If so, what's the part number.
Could
        you also send me that check-off list ?

        Thanks,

        Number one on the list of things to worry about - The choice of
Modbus I/F
        from the I/A Series.


        There are two for serial links:


        *    The PSS 21H-7G4 B3 <21h7/21h7g4b3.pdf>  Integrator 30, Style B
for
        Modbus Devices which speaks pure unadulterated Modbus and
        *    The Modbus Device Integrator from Ken Gunston's group which can
        handle almost any Modbus based device.


        As an example of the differences:


        *    The Integrator 30, Style B for Modbus Devices is a Modbus
Master
        only. The MDI can be either Master or Slave.
        *    The Integrator 30, Style B for Modbus Devices doesn't handle
        floating point values (only scaled integers (counts) are supported).
The
        MDI
        can handle 32 bit floating point values.


        I'll send you a check-off list that I've used before to qualify the
choice
        of Modbus interface under separate cover. It is not perfect, but it
is
        useful.

             Hi,

with
        about 120 =
             RTU's to our IA system with a CMP30B interface. I would like to
ask
        if =
             anyone has done this with a Zetron controller and if so what
        pitfalls I =
             might look for.=20
                  =20
                  The model 1700 uses modbus RTU protocol. =20
