ABB Backplane Communication and Interface Processing
The IMMPI01 manages communication exchange between host-level equipment and internal control system modules. It processes data routing, packet handling, and interface conversion through its onboard microprocessor architecture.
Furthermore, the module provides RS-232-C serial communication channels that support DCE and DTE operating configurations. The SCSI interface provides local parallel communication capability for compatible system devices.
The module operates through the ABB Infi 90 backplane structure and supports industrial control architectures requiring controlled data transfer between processors, supervisory computers, and system interface modules.
Frequently Asked Questions
Q: What communication interfaces are available on the ABB IMMPI01 module?
A: The IMMPI01 provides two RS-232-C asynchronous communication channels and one SCSI parallel local bus interface for external and internal system communication.
Q: Does the IMMPI01 retain configuration data after power interruption?
A: Yes. The module uses 256 KB battery-backed RAM to maintain stored configuration parameters during power loss conditions.
Q: What installation position does the IMMPI01 require in the control system?
A: The module is designed as a single printed circuit board assembly installed in one standard ABB Infi 90 module mounting unit slot.
Field Installation Guidelines
- Install the IMMPI01 only in the designated ABB Infi 90 or compatible Symphony module mounting position.
- Verify that the backplane connector is clean and correctly aligned before insertion.
- Confirm the +5 VDC supply connection and polarity before system energization.
- Route RS-232-C communication cables separately from high-current power conductors to reduce electrical interference.
- Maintain proper cable shielding and connect shields according to the control cabinet grounding practice.
- Check communication parameters after installation to confirm correct interface operation with connected devices.
- Follow ABB system documentation for module replacement, diagnostics, and firmware compatibility procedures.
