Lockouts
The YHC HART Communicator can be programmed to lockout certain standard functions that a supervisor
may wish to control. The functions included are used to set up the YHC for normal use, change online
HART device configurations, create offline HART device configurations, update the installed DOFs list
(HART device profiles), or to update the YHC’s operating firmware. For example, locking out the Configs
feature turns the YHC into a read only HART communicator while locking out DOFs and Firmware prevents
unauthorized updates. The lockout can be limited to individual Lockout Details items or all Lockout Details
items can be locked out at one time.
To enable the lockout feature, press the “3” key or move the selection cursor
to the
Lockouts
menu
option on the Configuration screen (see below left). Choose the
Lockouts
selection by pressing the
Chng
soft key. The YHC will enter the
Lockout Enable / Disable Screen
. The three choices and current status
information are provided (see below center):
