ibaBM-SLM
6.3.1
Properties
Rugged metal housing for DIN rail mounting
1 SIMOLINK bus connection, can be buffered against voltage failure (SIEMENS
SLM module)
SIMOLINK module address of the diagnostic unit is adjustable within ibaPDA
Two uni-directional fiber-optic links (3.3 Mbps) with ST fiber optic connections to
ibaPDA computer
2 wired connections (RS422 on RJ11 socket) for Notebook PC
Transfer of up to 128 analog (INT or DINT) + 128 binary signals. Each fiber-optic or
RS422 connection can transmit 64 Float and 64 binary signals.
Data transfer on fiber-optic links synchronous to SIMOLINK bus cycle
Parallel data transfer on fiber optic link and RS422, whereas only one RS422 inter-
face of an ibaCom-PCMCIA-F card can be used on the notebook side.
Unregulated 24 V DC power supply
Unregulated 24 V DC SIMOLINK buffer supply
Configuration is stored permanently in the device

Data types
The data to be measured from the SIMOLINK bus is defined by using a setup dialog
within ibaPDA. The following data types may be measured.
16 bit integer (INTLOW and INTHIGH: -LOW indicates lower word, -HIGH indicates
upper word of 32-bit data word)
32 bit integer (DINT)
bit; via ibaPDA packed binary input through bit selection from 16-bit status words
Each data type corresponds to a measuring value. Up to 128 analog (INT16; DINT)
and 128 packed binary signals per ibaBM-SLM device can be transmitted to ibaPDA.
Note
Regardless of selected data types, all data are transmitted as 32-bit IEEE floating point
values.
Due to the conversion from 24 bit measuring resolution to 32 bit format, inaccuracy
may occur when using DINT data format.
