NC2 and ACX57xx controllers with network security applied will no longer respond to a ping command after upgrading to newest firmware.
- Network Security
The ping command was used to monitor controllers offline/online status.
CX9680 and ACX57xx controllers (with network security applied) stopped responding to a ping command after respective firmware versions v2.100048 and v1.100052 were applied.
This is functioning as designed due to the hardening of the controller's firmware for security reasons when network security has been applied.
