How get this worked? SpaceLink+SmartlinkTCP+SmartlinkRTUx2+PowertTagx18

[pillbox]

Hello,

I have SmartLinkTCP with connected 2xSmartlinkRTU over modbus and 18xPowertags (see screenshot)
SmartLink configured with RCA iC60 channels
I get statuses from Powertags
I have no any status updates from Smartlink devices. Only first time after mapping.
Write to Smartlink channels is working fine
Sometimes i get error "method called on invalid context" in modbus error window
I tried pesistent connection and no persistent
How to get this working? And how to get it fast (i have to get quick status response)? 
Thank You
