Keyswitch
The Hand-held Monitor’s keyswitch can be used to restrict access to certain features of
the HHM.
With the key present, the switch can be placed in either “configure” (cfg) or “monitor”
(mon)
position.
cfg with the switch in Configure position, all HHM functions are available. In this
mode, the Hand-held Monitor can be configured to determine which of its fea-
tures will be usable once the key is removed.
mon: with the keyswitch in Monitor position, the HHM can monitor bus and block
data. Additional HHM functions, such as clearing faults or configuring I/O
blocks, can be used in Monitor mode only if the HHM has been set up to permit
their use.
The key must be present to move the switch from Monitor to Configure mode position;
it can only be removed in MON position. Two identical keys are supplied with each
Hand-held Monitor. The key should be removed if system security is a concern.
