Management of several keyboards.
9.11.2 Operation of the jog panels.
When enabling a keyboard (PANELOFF mark) and every time there is a keyboard change
(press a key, change a switch, etc.), the channel assumes the status of the keys and the
position of the switches of the new keyboard with the active values. If necessary the PLC
program must include the proper restrictions to avoid sudden feedrate changes due to
different positions of the feedrate override switch on the different keyboards. It is also
recommended to manage the user keys using up and down flanks to avoid the possible
activation of devices when changing keyboards.
Every time the active keyboard is changed, the new keyboard updates at the PLC the
information on all the marks and registers associated with the keyboard itself (KEYBD1_n,
KEYBD2_n, KEYDIS1_n a KEYDIS3_n, KEYLED1_n, KEYLED2_n) and the generic ones
associated with all the keyboards (KEYBD1, KEYBD2, KEYDIS1 to KEYDIS3, KEYLED1,
KEYLED2).
Behavior of the keys and the switches.
The keys from the jog panel.
The keys of each jog panel are only effective for each channel with which the keyboard is
associated; whether it is the active channel or not. The following keys have a different
behavior.
• The [RESET] key affects the channel associated with the keyboard where the key has
been pressed and the channels that belong to its group.
• The keys to select the work mode (automatic, jog, etc.) only affect the active channel.
Feedrate override selector.
If the keyboard is associated with a particular channel, an override change only affects that
channel, even if it belongs to a group. If the keyboard is associated with the active channel,
an override change affects all the channels of the system at the same time, whether they
belong to a group or not.
