Re: [foxboro] Connecting Limitorque & Integrator 30


Scott,

How do you fire the MCOUT block from the GDEV block and how do you set the
required value to be sent  to the device into the MCOUT block . The MCOUT
block would have to output a 0900 when the COUT_1 parameter of the GDEV
block representing the first pump in a SRB unit is set to true(starting the
pump), a 0A00 when COUT_2 is true(stopping the pump),a 0B00 for starting
the second pump, a 0C00 for stopping the second pump an so on.

Regards,
Douglas

We use gdev block also but we set the output to fire a mcout. That way =
you
and have all you register in one block. The inputs we use mcin the same =
way.
With no problems

Subject: [foxboro] Connecting Limitorque & Integrator 30




Does anybody have any experience connecting Limitorque's two wire valve
system (with UEC
and Six Relay Board units) via an I/A Series Integrator 30 for modbus ?

We are trying to configure an Integrator 30 to be connected to the DCS =
port
of a  DC100 master
station for Limitorque's two wire system. We are using the MOVLV and =
the
GDEV blocks to configure
valves and pumps respectively, but we have encountered a problem with
sending commands
to the SRB units whose 6 relays(K1 throuhg K6)  are commanded by the =
modbus
06 command
(Preset single register) instead of the 05 command (Force single coil)
which is used for UEC units.
As far as I can see the output of the MOVLV and GDEV blocks are boolen
values suited for the
05 command and not an integer value which would be required for the 06
command.

I would appreciate hearing from anyone who has tackled this situation
before.

Regards,
Douglas
