Input/output blocks
Function Blocks - FM 458-1 DP 1-3
Edition 12.2004
• INI
as for the "initialization phase“ mode
• OFF
Output QF is set and processing terminated.
AD
Hardware address of the SBM2 (initialization input)
TYP
Encoder type
TYP = 0 not available
TYP = 1 EQN1325
TYP > 1 incorrect encoder type
(initialization input
default: 1)
BDR
Baud rate
BDR = 0 100 kHz
BDR = 1 500 kHz
BDR = 2 1 MHz
BDR = 3 2 MHz
BDR > 3 incorrect baud rate
(initialization input
default: 0)
EXP
Resolution in bits
Value range: 16 ≤ EXP ≤ 32
(default: 23)
DM
Configure the block in cyclic tasks or interrupt tasks
DM=0 SBM in interrupt tasks
This mode is only practical in conjunction with the alarm-
controlled SIMOLINK events (sync interrupt from SLB). Using this
sync interrupt, in this mode, the values of the SBM module are
de-latched. The block should then be configured in the alarm task
started by the same event.
DM=1 SBM in cyclic tasks
If the block is computed in cyclic tasks, then the SBM2 module
register is read-out in the system mode. The contents of the register
are then read-out in the normal mode and the values for the output
connections computed.
(initialization input
default: 0)
RS
Rated speed in revolution/min (RS>0) (default: 1.0)
YPI
Position in increments (default: 0)
RPI
Max. number of increments per revolution
(depending on the input connection EXP)
(default: 0)
Y
RS
RPMmin
encoderrotary the speedform Normalized
(default: 0.0)
U
Revolutions (default: 0)
QF
Group error message
QF=0 no error, QF=1 for error (if YF≠0)
(default: 0)
YF
Error status of the block
YF=0x0000 no error, YF>0x0000 (refer to error statuses)
(default:
16#0000 0000)
