9.3 Displaying messages, errors and screens
The PLC has a series of marks that allow messages and errors to be displayed in the CNC, as well
as displaying screens which have been defined previously by the user.
Displaying messages
The PLC has 255 marks, with their corresponding mnemonic for displaying messages in the CNC.
If one of these marks is activated (high logic level), the CNC will display the selected message
number and its associated text on the PLC message display window (upper right-hand part).
The CNC allows a text to be associated to each PLC message (PLC message editing mode).
If the PLC activates 2 or more messages, the CNC will always display the message with the highest
priority, this being understood as being the message with the lowest number. In this way, MSG1 will
have the highest priority and MSG255 the lowest priority.
In this same message display window, the CNC can show the character + (plus sign), which indicates
that there are more messages activated by the PLC, and these can be displayed if the active
message page option is accessed in the PLC operating mode.
A message can be erased by deactivating it from the PLC program (low logic level) or from the CNC
keyboard, after selecting it on the active messages page.
Nevertheless and depending on the program, the PLC may reactivate this message in the following
cycle.
Example:
DFU I10 = MSG1
I10 = MSG2
1. Input I10 changes from 0 to 1.
Messages MSG1 and MSG2 are activated.
2. The user deletes the messages using the keyboard.
3. In the next PLC cycle, since I10 is kept at “1”, MSG2 is activated again.
