Sending Alarm Messages (S5F1)

Series
MELSEC-Q series
MELSEC iQ-R series
When an alarm message (S5F1) is sent from the Programmable Controller CPU, the SECS/GEM communication software
notifies the host of the alarm message automatically simply by Alert Status and a handshake operation of Alert Set/Reset
Notification, without defining multiple alarm messages as transactions.
Usage method
■Alarm information definitions
Alarms to be disclosed by the equipment are defined by the setting tool in advance.
Each alarm is managed by a unique identifier and alarm number appended to each alarm. The SECS/GEM communication
software and Programmable Controller CPU transfer the alarm state by setting the "Alarm No." as a key.
The alarm information is configured as shown below.
• Non-GEM version: configured at the "Alarm Settings" screen. ( Page 119 Alarm settings)
• GEM version and advanced GEM version: configured at the "Alarm Definition" screen. ( Page 194 Alarm Definition)
■Alarm notification settings
Configure the handshake to report the alarm.
