Overview
Configured for cyclic execution of control algorithms and deterministic data exchange in ABB Advant OCS platforms, the ABB DSPC173 (base model 57310001-MT Processor Module) provides direct electrical interfacing via the controller backplane. It processes I/O scan data and maintains synchronization across the Advant Controller 400 Series communication network without external protocol translation.

Backplane Bus Communication Velocity and Firmware Flash Compatibility
The DSPC173 interfaces with the Advant OCS backplane using a parallel bus architecture operating at fixed clock cycles determined by the AC410/AC450 CPU master clock. Firmware images are loaded via flash memory integrated into the module PCB; compatibility is restricted to specific Advant Controller firmware branches. Cross-version flashing outside the validated matrix will halt backplane arbitration and force a hardware fault state until reflashed with certified firmware.
Frequently Asked Questions
Q: Does the DSPC173 support hot-swap insertion?
A: No. Power must be removed from the subrack prior to installation or removal to prevent backplane bus contention and electrical overstress on onboard drivers.
Q: Can the DSPC173 operate in mixed-redundancy configurations?
A: Only when paired with identical DSPC173 modules running the same firmware revision and configured within the same AC400 redundancy set.
Q: What is the maximum permissible backplane current load per module?
A: The module draws its operating current exclusively from the backplane supply rails; total loading must remain within the AC400 subrack’s rated bus current capacity as defined in the hardware manual.
Field Installation Guidelines
Install the DSPC173 into the designated processor slot of the Advant Controller subrack. Ensure all adjacent modules are fully seated before applying power. Use ESD protection during handling. Verify backplane connector alignment prior to latching the module into place. Do not apply external voltage to any backplane pins. Confirm cooling airflow path is unobstructed after installation.
