LD_STS_SLOT_0 This bit indicates by a status change (toggling) that the load request for Slot 0 (LD_SLOT_0)
has been detected and executed.
LD_STS_SLOT_1 This bit indicates by a status change (toggling) that the load request for Slot 1 (LD_SLOT_1)
has been detected and executed.
POWER_ERROR For an S7-1500 technology module, this bit indicates that the supply voltage L+ is not available
or too low or that the front plug is not plugged in. For an ET 200SP technology module, this bit
indicates that the supply voltage L+ is too low.
If you have enabled the diagnostic interrupts, the respective diagnostic interrupt is triggered in
the event of errors in the supply voltage. For details on the diagnostic interrupts and the correc-
tive measures they require, refer to the device manual for the respective technology module.
If the supply voltage L+ is available at a sufficient level once again, POWER_ERROR is auto-
RES_EVENT_ACK This bit indicates that the reset of event bit EVENT_SYNC, EVENT_CMP0, EVENT_CMP1,
EVENT_OFLW, EVENT_UFLW, EVENT_ZERO is active.
STS_CNT This bit indicates that at least one count pulse or a position value change has occurred in the
This bit indicates the status of digital input DI0.
This bit indicates the status of digital input DI1.
This bit indicates the status of digital input DI2 of the TM Count .
STS_DIR This bit indicates the count direction of the last count pulse or the direction of the last position
value change.
0 means: Down
1 means: Up
This bit indicates the status of digital output DQ0.
This bit indicates the status of digital output DQ1.
STS_GATE This bit indicates the status of the internal gate when using an incremental or pulse encoder.
0 means: Gate closed
STS_M_INTERVAL This bit indicates that at least one count pulse or a position value change was detected in the
previous measurement interval.
STS_READY This bit indicates that the technology module supplies valid user data. The technology module
has been started up and configured.
STS_SW_GATE This bit indicates the status of the software gate.
0 means: Gate closed
