ION7330 & ION7350 TCP

[EvonneYin]

Hi All,

How many concurrent TCP connections an ION7330 and ION7350 can support?

Same question as the PM5000 series

but for ION7330 and ION7350?

Many thanks!

1x for each protocol/port. 🙂 Unfortunately, as many have found out the hard way. You cannot have multiple people reading ION on 7700 or Modbus TCP 502, or EtherGates (7801 and 7802)

Can someone please post KB 200829 - Ethernet ports and socket summary on ION meters? (it must have been updated since 2009, which is the copy I have)

Also see RESL183645, & RESL199661, & RESL194118

There should be an option to disable one or both the serial ports and "convert" them to a TCP socket connection.  Check the list of protocols on the serial port and see if there is a "disable" option.  That should allow an additional connection to be made.

Note that the additional connections are still multiplexed over the internal serial port between the ethernet card and the main meter so there may be a slight performance drop.

If how to do this post back here and I will have a quick look.  When I wrote this code years ago I seem to remember adding this feature in but it may not be the most obvious how to turn it on.

Hi Hal! Sounds like an interesting workaround. However, I have never seen "disabled" as a setting that you could choose on any of the serial ports. This is just from my memory, but I think your only options are ION, Modbus RTU, DNP 3.0, and in the case of COM EtherGate as well.

Thank you. I knew I can count on you guys.

Hmm.  You are right.  I just checked on some of the devices in the our lab and they don't have that option.  I seem to remember we did this during development though.  Maybe it is an option only in the latest ethernet card firmware. I am not sure how we ended up doing it - it was a *long* time ago that code was written.
