Re: [foxboro] Modbus gateway question

Can't speak to trauma, but:

a) You want to be at V6.5 (51b/c), V6.5.1 (51d/e) or 7.1 (f/g). 
b) Getting there requires a Day 0 and CP reboots to cross the V6.3/6.4
   barrier.
c) Displays don't change - either FV or DM
d) CP40a can still be booted, monitored, and configured using the tools you
   have today
e) You do not need to change historians.

Sounds like your biggest issue will be 51b support. 

Does this help?

how big is the "trauma" to uograde versions, let's say from 4.3 to 7 (or one
to allow Cp60 and fbm200 for comm) ??
displays ? cp40a configs? historian ? etc
we have a medium size net with ver 4.3, cp40a and 51B boxes... and we are
looking for improve use of communications toward new 200 series (modbus,
profibus, whatever..no more int30...)

Asunto: Re: [foxboro] Modbus gateway question



This coming holiday we will be installing a new AW51F (host) to our system
running ver 7.0,
we will also be adding a CP60 and several of the 200 series FBM's. The rest
of our system will
remain at version 6.3 (3 "B" boxes).
Is the FBM224 a viable option for us?

thanks,

Ken Moore

Ken,

Re: "peer-to-peer" Modbus
I'm not aware of a 'peer-to-peer' version of Modbus. Can you tell me more
about what you are using and the configuration? This sounds odd to me.


Re: General use of Modbus Gateway (MDGW) and Modbus Device Integrator (MGI)
The MDGW and MDI are both Modbus RTU masters and control the link.

In general, one puts multiple slave devices on the link and let the one
port
serve them all.

There are extra ports (4 on the CmP15/DI15 HW and 2 on the CmP30/DI30 HW),
but they have an impact on each other. The overall performance of the
device
does not improve (in fact it declines) if they are used separately.

I'm pretty sure that this is covered in the manual, but it's been a while.
Do you need a copy?

I don't suppose you have a CP60 at V6.5.x? If so, you could use the FBM224.

Subject: [foxboro] Modbus gateway question


I currently have a modbus gateway that is connected to a Texas Instruments
PLC, via peer to peer.
Is it possible to add an additional peer to peer connection on the second
port?
If I upgrade to an Integrator 30 , would two peer to peer connections be
possible?


thanks,
