Cause

Lon Values going into and out of default

Resolution

• Compare the IC-LON’s Receive heartbeat set in the “gateway.txt” file in the IC-LON controller, to the send heartbeat set in the controller.
  The recommendation is for the receive heartbeat be set to 2-5 times the send heartbeat of the field controller.
  Starting at 2 times, then increasing if the problem persists.
• If the controller doesn’t have a heartbeat and the LON value rarely changes, disable the receiver heartbeat in the IC-LON’s gateway.txt file by setting the heartbeat to 0.

Example:

1     2     3        4      5   6  7

2,   2,  112,  1293,  0,  0, 0

The Sigma system is now out of its support period, consideration should be given to transitioning or upgrading to
