Message signals interface (DB 58)

ACKNOWLEDGE NC EMERGENCY
1 signal: EMERGENCY STOP acknowledged to the NC
0 signal: No effect
Note:
• ACKNOWLEDGE NC EMERGENCY STOP affects all NC channels when NC IN EMER-
GENCY STOP STATE is present.
• ACKNOWLEDGE NC EMERGENCY STOP can generally be effected with the RESET key
(must be implemented by user).
• The signal is static. If this signal is set while you are remedying the cause of error the
EMERGENCY OFF state of the control is acknowledged.
DISPLAY IN MESSAGE LINE ERROR MESSAGES
1 signal: The first error message of the buffer memory for error messages is entered in the
message line (line 2 of the screen).
0 signal: No error messages are entered in the message line (line 2 of the screen).
Note:
The bit is interpreted in PLC I only.
DISPLAY IN MESSAGE LINE OPERATIONAL MESSAGES
1 signal: The first operational message of the buffer memory for operational messages is
entered in the message line (line 2 of the screen).
0 signal: No operational messages are entered in the message line (line 2 of the screen).
Note:
• The bit is interpreted in PLC I only.
• If the display bits for error and operational messages are set, the error messages have a
higher priority. Even if the display in the message line is not selected, current error and
operational messages are still shown in the displays selected by softkeys.
