[RE-wrenches] No Communication to XW CC

[William Miller]

Sandra:



I have frequent communications problems with XW xanbus devices.  At one
point I was told by Schneider tech support that all Cat5 leads need to be a
minimum of 6 feet in length.  Is this true?

Hello Drake.

In the Xanbus network, you have devices with power such as inverters, and
other devices without power.

You can not connect an SCP directly to an MPPT60, because both SCP and
MPPT60 have no power, but if you have an inverter in the network, it should
give sufficient power for the devices.

There are several reasons why a device that is still fully functional but
not show up on the network. This ranges from the minor CAT5 cable problem
to maybe a damage communication card. Some may be solved with a simple
factory reset, and other cases may require a replacement.

However, without the full context of the conversation, I do not see how
connecting ComBox or SCP will make any difference. Although, the ComBox as
an AC power supply it will not power the Xanbus network, it is only to
power the ComBox.

As far as connecting ComBox directly to your laptop without a router, this
is possible, but you need to change your network setting on the laptop.

Hello Wrenches,



We have a situation on a repair job (that I didn't install), where the
charge controllers are not showing up on the SCP. There are 3 charge
controllers, two 600 V and one 150 volt units. There is a ComBox and and
SCP.



One Schneider tech recommended that I unplug the SCP and plug a laptop
directly into the ComBox..The manual shows a router being used.



Can a laptop be plugged directly in to a ComBox? Will this be helpful in
finding the missing CCs?



Even with new Ethernet cables, the CCs don't show up.



Thanks,



Drake
