I have checked the ENBT staus in "web page" by providing the Ip address and found that the" open format reject " in "connection manager statstic" is quite high(22182) . What it indicate? any anyone help...

Do you have the latest firmware release for your module? What version do you have and which ENBT module. Is it A or B.

Been having the same problem with an installation installed in 2007. ENBT/A would lock up, REDs would come on and an Exception Code would be displayed. Only removing and reinserting would resolve the problem. This customer is a 5 hour flight away, but I do have VPN. I sent them a 1756-ENBT/B anw will flash upgrade the /A when the /B is inserted and is used for Ethernet communications.

Take a look at what the RPIs are set for in the Ethernet devices on your IO tree. See if their are any that can be increased without adverse affect.

it is indeed ENBT A..
Is this required to be changed to ENBT B?

the version is indeed quite old 2.004..(some others are 3.009)

Mr. Mark..
I dont do the firmware update fearing that might make some compatibility issue...Frankly , the compatibility issues for rs link/logix/panel view all give me quite a sleepless nights ...

I upgraded 2 of ours to version 5.0 the other day. They had older versions 3.1 and 3.9. We had a problem where a duplicate IP address was causing a processor to lose communications. I am hoping the upgrade will help this if it ever occurs again.

That is probably the issue I am having with my customer's location using the ENBT/A. Eversince this 4 year old PLC install was put on their corporate network this past January, this problem has been randomly occuring.

duplicate ip is not the issue for sure.

GOT IT LASTLY...

Series B does not exist. There is no such thing as a series B ENBT.
Series A is the current shipping series.
