[RE-wrenches] No Communication to XW CC

[Sandra Herrera]

William,

I will need system specific information to make any comments on your reported communications issues.

As far as the recommendations for 6 foot CAT5, that was done 5 to 7 years ago for a specific application, and it is still valid when working with large systems, where you are pushing the Xanbus network maximum.

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
