Status Code
The action point for Alarm 5 with the set alarm value exceeded the process variable
212
minimum value or maximum value.
The action point for Alarm 6 with the set alarm value exceeded the process variable
213
minimum value or maximum value.
214 to 219
The action point for Alarm 3 with the set hysteresis exceeded the process variable
220
minimum value or maximum value.
The action point for Alarm 4 with the set hysteresis exceeded the process variable
221
minimum value or maximum value.
The action point for Alarm 5 with the set hysteresis exceeded the process variable
222
minimum value or maximum value.
The action point for Alarm 6 with the set hysteresis exceeded the process variable
223
minimum value or maximum value.
224 to 229
230 The Alarm 3 delay time was set to a value of 10,001 or higher.
231 The Alarm 4 delay time was set to a value of 10,001 or higher.
232 The Alarm 5 delay time was set to a value of 10,001 or higher.
233 The Alarm 6 delay time was set to a value of 10,001 or higher.
234 to 239
When the Alarm 3 alarm type was set to the upper/lower limit alarm or the upper/
240 lower limit alarm with standby, the Alarm 3 hysteresis was set to a value that does not
satisfy hysteresis < alarm value.
When the Alarm 4 alarm type was set to the upper/lower limit alarm or the upper/
241 lower limit alarm with standby, the Alarm 4 hysteresis was set to a value that does not
satisfy hysteresis < alarm value.
When the Alarm 5 alarm type was set to the upper/lower limit alarm or the upper/
242 lower limit alarm with standby, the Alarm 5 hysteresis was set to a value that does not
satisfy hysteresis < alarm value.
When the Alarm 6 alarm type was set to the upper/lower limit alarm or the upper/
243 lower limit alarm with standby, the Alarm 6 hysteresis was set to a value that does not
satisfy hysteresis < alarm value.

Alarm 3 value (S1+23)
Set the value that will be the trigger condition for the alarm. The value to set differs by the alarm type.
The content for the alarm value is as follows.
Alarm Type
Upper Limit Alarm
Lower Limit Alarm
Upper/Lower Limit Alarm
Upper/Lower Limit Range Alarm
Process High Alarm
Process Low Alarm
Upper Limit Alarm with Standby
Lower Limit Alarm with Standby
Upper/Lower Limit Alarm with Standby
*1 No alarm action when the alarm value is 0.
S2: Initialization Input
When the initialize input is on, the control registers (data registers) are overwritten with the values configured on the WindLDR
input tab, control tab, and output tab. If you want the initialization to be performed just one time, please use a SOTU (shot up)
or a SOTD (shot down) instruction.
