Table 3-8 Access To The Control And Feedback Interface In Step 7 Programming - Siemens SIMATIC ET 200S Operating Instructions Manual

1Count5V/500kHz
3.6 Count Modes
Feedback bits Notes
STS_DO2 DO2 status
The STS_DO2 status bit indicates the status of the DO2 digital output.
STS_GATE Internal gate status: Counting
STS_LOAD Load function running (see figure below)
STS_ND Zero-crossing in the count range when counting without a main counting direction. The bit must be
reset by the RES_STS control bit.
STS_OFLW High counting limit violated
STS_UFLW Low counting limit violated
Both bits must be reset.
STS_SYN Synchronization status
After successful synchronization, the STS_SYN bit is set. It must be reset by the RES_STS control
bit.
