Start-Up 02.2001 SLE / SLE-DP – SIMOLINK Encoder
GWE-477 763 4070.76 J Siemens AG
6-18 Operating Instructions SIMOVERT MASTERDRIVES
Bit 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
6-= 0
7-= 0
8-= 0
9-= 0
10 - = 0
11 - = 0
12 - = 1
13 - = 1
14 - = 1
15 - = 1
Bits 6…15 are not used. When read, they have the status value
indicated on the left.
Table 6-11 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.
