FM 350-1 Counter module
Manual, 05/2011, A5E03648639-01
This bit indicates that a data error was entered in the checkback interface.
The bit will be set if diagnostics data record DS1 was updated to signal a diagnostics event. The
bit will be reset when data record DS1 has been read. If no diagnostics interrupt is enabled, this
bit may be used as init bit for the FC DIAG_INF you embedded in OB1.
FM 350-1 sets this bit when it performs a restart, or detects a system startup, regardless of
whether the system starts up automatically or manually. The FM_NEUST bit will be reset at the
next positive edge at bit NEUSTQ. FM 350-1 will then accept control commands, and allow the
input and output of values.
FM 350-1 deletes this bit when it performs a restart, or detects a system startup, regardless of
whether the system starts up automatically or manually. It will be set after you reset the
FM_NEUST bit.
This bit will be set after an operator error was logged at the checkback interface. It will be reset
after bit OT_ERR_A is reset. As long as bit OT_ERR is set, the function does not report any
further operator errors.
This bit will be set when the module parameters are free of errors. The parameter data record on
the module does not contain any errors. This bit will not be set, however, unless bit FM_NEUSTQ
was reset. From this moment on, the values in the checkback interface are valid and up to date.
Bit used to acknowledge simultaneous changes of the reaction of DO0 and DO1, and of the
hysteresis and pulse duration. Transfer the old values if you want to discard all changes.
Status at output DO0
Status at output DO1
Acknowledgement bit for loading the high limit
Acknowledgement bit for loading of the refresh time
This bit indicates the count direction of the counter:
0 = Up (LED DIR is off)
1 = Down (LED DIR is lit)
This bit indicates the gate status.
0 = Gate closed
1 = Gate open
Acknowledgement bit for loading the low limit
This bit indicates the saved status, which shows the overflow of a measured value. The saved
status is reset with RES_ZERO by acknowledging.
Acknowledgement bit for resetting the stored states in the acknowledgement bits STS_OFLW,
STS_UFLW and STS_COMP1
This bit corresponds to counter bit 2
0 = LED CR is off
1 = LED CR is lit
Status at digital input DI-Set
Status at digital input DI-Start
Status at digital input DI-Stop
This bit indicates the saved state, which shows underflow of a measured value. The saved status
is reset with RES_ZERO by acknowledging.
