■Status device
Set the device for storage of the status of the SSCNET/H head module with a bit device or word device.
• Refer to device list for the range of bit devices and word devices that can be set. (Page 75 Device List)
• The device uses 16 points (1 point if a word device) from the specified device number. The details stored in the status
device are shown below.

Operation cycle
Can be used to judge whether there is an error or not by the signal turning ON when
a stop error is detected in the SSCNET/H head module.
The applicable error code is stored in the error code signal of the monitor device set
in Monitor device. (Page 201 Monitor device) If error is reset by turning ON the
error reset command, or turning ON the SSCNET/H head module power supply
again, the signal turns OFF.
Operation cycle
Can be used to judge whether there is an error or not by the signal turning ON when
a continue error is detected in the SSCNET/H head module.
The applicable error code is stored in the error code signal of the monitor device set
in Monitor device. (Page 201 Monitor device) If error is reset by turning ON the
error reset command, or turning ON the SSCNET/H head module power supply
again, the signal turns OFF.

Operation cycle
Stores the operating status of SSCNET/H head module.
0: No communication
1: STOP status
2: RUN status
3: ERROR status
Stores the error code when an error is detected in the SSCNET/H head module.
(Continue error and stop error)
If error is reset by turning ON the error reset command, or the SSCNET/H head
module power supply is turned ON again, this device is also cleared.
At a communication retry
Holds the accumulative count for communication retry with the SSCNET/H head
module.
Counts each time a communication retry with the SSCNET/H head module occurs.
When communication is successful, the count is "0".
