| The buzzer beeps continuously. |
|
|
| When the GP's buzzer keeps sounding, one of two issues may be occuring: |
|
|
|
1 : The buzzer output bit in the system data area
is ON. |
| Built into each GP, is a block of memory called the
system
data area. One of the bits in this area turns on the GP's buzzer.
(When connecting to a PLC, it is Bit 01
of Word +14. When using Memory Link, it is Bit 01 of Address
11). By default, this block of memory is written into your PLC. If you inadvertently turn ON this bit, your buzzer will sound. |
| |
 |
| |
If you use the bit for a
switch or turn it on with the ladder on
the PLC side, the buzzer of the GP will
start sounding. |
|
|
 Recovery Method |
Disconnect the PLC's communication cable
and turn OFF the power supply of the
GP. The values in the system data area will
be reset and the buzzer output will be OFF.
If the PLC communication cable cannot be
disconnected, use the PLC to turn OFF the buzzer
output bit in the system data area (When connecting to a PLC, it is Bit 01
of Word +14. When using Memory Link, it is Bit 01 of Address
11). |

|
|
| 2: The GP's system is damaged. |
| When the GP's system is damaged, the GP's touch doesn't function
and the buzzer won't stop beeping. In most cases,
an error, [System Error], is displayed.
|
|
| Recovery Method |
| Disconnect the PLC communication cable
and turn OFF the power supply
of the GP. If the symptom still remains, download
the project file to the GP again using a Force System Setup (in the Transfer Settings). |
