Backplane Bus Communication Velocity and Network Integrity
The GE Fanuc IC693ALG390 interfaces with the main Series 90-30 backplane bus to transfer 12-bit digital profiles into internal digital-to-analog converter registers. The module maintains a deterministic 5 ms update rate across both voltage channels simultaneously, ensuring output tracking stability regardless of changes in backplane bus communication velocity or active network nodes. Galvanic isolation circuits rated at 1500 V RMS physically decouple the field terminal connections from the internal logic bus to suppress common-mode noise and safeguard the main PLC processor from field-side voltage spikes.
Frequently Asked Questions
Q: Does this module draw its operational loop power directly from the 90-30 backplane? A: No. The internal digital-to-analog conversion circuits and analog output loops are powered via an external 18 to 30 VDC field supply connected to the terminal block. The module only draws a minimal logic-level initialization current from the backplane +5 VDC line.
Q: What happens to the voltage outputs if the PLC enters a Stop mode or backplane communications fail? A: Upon a loss of backplane data transmission or CPU stop command, the digital-to-analog converters lose active register updates. The analog circuits drop the physical output values to a default safe state (0 VDC) to prevent downstream actuators or positioning loops from maintaining obsolete setpoints.
Field Installation Guidelines
- Field Power Isolation Requirements: De-energize both the backplane chassis power and the 24 VDC external field power loop before attaching or removing the field wiring connector terminal block to prevent active channel arcing.
- Shield Terminal Termination: Connect the braided shield of the shielded twisted-pair signal cables directly to the chassis ground bar or designated shield terminals on the rack. Do not allow shield braids to remain floating or touch live electrical components.
- External Voltage Specifications: Ensure the external DC supply provides a regulated voltage between 18 and 30 VDC. The supply must not exhibit a voltage ripple exceeding 10% to prevent degradation of the factory accuracy threshold (+/- 5 mV).
