Device Design
Two circuit boards encased in a robust iba metal housing provide the circuitry neces-
sary for interfacing with the Siemens Simolink bus. A basic circuit board handles the iba
technology and the SLB module handles the Siemens SLB technology.
7.1
Base Circuit Board
Device power supply (unregulated 24 V DC) with 3 status LEDs (Run, Link, Error)
Microprocessor with firmware for control of data transfer to ibaPDA
RAM and flash EPROM storage of data, code and parameter sets
Control of two uni-directional fiber-optic (3.3 Mbit/s) and two RS422 (RJ11) external
interfaces
9-pin Sub-D interface for configuration
Internal interface for integration of Siemens SLB module
Permanent storage of SIMOLINK addresses, conversion tables and Profibus pa-
rameters in the device
7.2
SIMOLINK Board (SLB Module)
The standard SIEMENS SLB module features:
Bi-directional fiber-optic interface to connect the SIMOLINK bus
Microprocessor with firmware for control of data transfer to/from SIMOLINK bus
Flash-EPROM code storage
Dual port RAM for transfer of data to base circuit board
Terminals for 24 V DC buffered power to SLB; can be used to maintain SIMOLINK
bus integrity in the event that the ibaBM-SLM device is not powered
3 LEDs (Link, Run, DPR)
