Microgateway
In previous Flash Card versions, “Start Inhibit” and “Modifi ed Run” codes were transmitted into “Cycling” and
“Safety” shutdown slots in the Microgateway. This alarmed external devices that a Cycling or Safety shutdown
has occurred, when in reality, a Start Inhibit such as Anti-recycle or a Modifi ed Run event such as Current Limit is
in effect. This was incorrect operation. In this version, the codes are transmitted into the proper slots in the Micro-
gateway.
Security Log Screen
In previous Flash Card versions, some setpoint changes were not logged in metric mode. All setpoint changes are
now logged.
