9. Key locking by the PLC
In order to prevent the operator from performing certain functions depending on the control system status, the PLC is able to lock out the terminal. There are 3 reserved words in the dialog table that allow various keys to be locked. These keys are:
- static function keys,
- system keys,
- numeric keys.
Word bit at 1 = key locked
The word concerning the system keys also contains a bit allowing the total lock of the keyboard or of the tactile pad. This total lock also affects the keys of a terminal with tactile keys.
See chapter C, § 2. Dialog table content, Page 9
, for the word coding procedure.
WARNING
UNINTENTIONAL EQUIPMENT OPERATION
Pressing the MENU key allows the inexperienced and untrained operator to accidentally display the wrong page, modify the terminal configuration, or lose the messages and alarms on the screen. This can lead to confusion, panicking, and, as a consequence, loss of control over the machine. It is strongly recommended that the PLC be programmed to lock the MENU key as well as the other currently unused keys in order to prevent this from happening.
Failure to follow this instruction can result in death, serious injury,
or equipment damage.
