Result of limit monitoring (Totalizer 1 / Totalizer 2)
The result of limit monitoring is returned at the interconnectable output parameters:
● Tot1_AH_Act/Tot2_AH_Act = 1:
Limit for high alarm reached or exceeded
● Tot1_AL_Act/Tot2_AL_Act = 1:
Limit for low alarm reached or undershot
● Tot1_WH_Act/Tot2_WH_Act = 1:
Limit for high warning reached or exceeded
● Tot1_WL_Act/Tot2_WL_Act = 1:
Limit for low warning reached or undershot
You can use Feature bit 29 (signal limit overshoot/undershoot) to determine whether the
output parameter triggers limit monitoring with the value "0" or "1".
You can use Feature bit 28 (disabling operating points) to disable limit monitoring while
message suppression is active (MsgLock = 1).
Activating limit monitoring (Totalizer 1 / Totalizer 2)
Monitoring is always enabled using the input parameters:
● Tot1_AH_En/Tot2_AH_En = 1: Monitoring of the high alarm limits
● Tot1_AL_En/Tot2_AL_En = 1: Monitoring of the low alarm limits
● Tot1_WH_En/Tot2_WH_En = 1: Monitoring of the high warning limits
● Tot1_WL_En/Tot2_WL_En = 1: Monitoring of the low warning limits
Predefinition: All monitoring functions are activated.
Message suppression (Totalizer 1 / Totalizer 2)
The corresponding message is suppressed using the parameters:
● Tot1_AH_MsgEn/Tot2_AH_MsgEn = 0:
Alarm (high) messages are suppressed
● Tot1_AL_MsgEn/Tot2_AL_MsgEn = 0:
Alarm (low) messages are suppressed
● Tot1_WH_MsgEn/Tot2_WH_MsgEn = 0:
Warning (high) messages are suppressed
● Tot1_WL_MsgEn/Tot2_WL_MsgEn = 0:
Warning (low) messages are suppressed
The output of messages is not suppressed when the block is installed (all xx_MsgEn
parameters are preset to 1). Messages can only be output if limit monitoring of the additional
analog value has been enabled.
Operation in the faceplate
You can also edit the limits and the hysteresis using the faceplate.
