Designation
Meaning
0
’SYNC toggle’
Switches between 0 and 1 after 256 SYNC interrupts have been received
(sign-of-life check when pulse output is enabled).
1
’SLE-DP status’
Checkback from DIL switch bit and PROFIBUS output data word; indicates
whether parameterization is in progress or SLE-DP is active.
’1’ = SLE-DP active
’0’ = SLE-DP not active
2
’PULSE mode’
Status of encoder interface; indicates whether SLE-DP is outputting pulses.
Corresponds to ’SLE-DP status’ bit in SIMOLINK actual value of SLE-DP.
’1’ = Pulse output
’0’ = No pulse output
3
’SYNC monoflop’ Status of SIMOLINK ring; indicates whether SYNC interrupts are being
received. Logical ’1’ equals steady illumination of the SYNC LED.
’1’ = SYNC telegrams
’0’ = No SYNC telegrams
4
’Incorrect SYNC
cycle’
Checkback indicating whether SLE-DP can operate with the selected
SIMOLINK cycle time (251 or 503 telegram transit times). Logical ’1’ equals
SYNC LED flashing at approximately 2 Hz.
’1’ = Incorrect cycle time
’0’ = Correct cycle time
5
Parameter
setting error
Checkback indicating whether ORing of DIL switch and PROFIBUS output
data word has produced valid address. Logical ’1’ equals SYNC and Z-PULSE
LEDs flashing at approximately 2 Hz.
’1’ = Parameterization error
’0’ = Parameterized correctly

SLE-DP; meaning of PROFIBUS input data word
With correct parameter settings and pulse output enabled,
W#16#F00F and W#16#F00E (S7 syntax)
are displayed alternately in the input data word.
