■Monitor device
Set the devices for monitoring the status of sensing module with a word device.
• Refer to device list for the range of word devices that can be set. (Page 75 Device List)
• The device uses 10 points (word) from the specified device number. The details stored in the status device are shown
below.

■Command device
Set the device for issuing commands to the sensing 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 command

Refresh cycle Details
*1
Operation cycle Stores the operating status of sensing module.
0: No communication
1: STOP status
2: RUN status
3: ERROR status
Stores the error code when an alarm/warning is detected in the sensing module.
If error is reset by turning ON the alarm reset command, this device is also cleared.
At a communication retry Holds the accumulative count for communication retry with the sensing module.
Counts each time a communication retry with the sensing module occurs. When
communication is successful, the count is "0".

Refresh cycle Details
 
Main cycle Clears the error code storage device and resets the alarm/warning detection signal of
the sensing module. At an alarm reset command, turn this signal OFF after
confirming the alarm/warning detection signal of the sensing module is turned OFF.
However, depending on the alarm of the sensing module, an alarm reset may not be
executed, or conditions may apply to the alarm reset. In this case, the error code
storage device is not cleared and the alarm detection signal is not reset, even if an
alarm reset is executed. Refer to the following for details.
