Backplane Bus Communication Velocity & I/O Density Scaling
The CI741F module establishes deterministic cyclic communication over PROFIBUS DP network infrastructures while maintaining backplane bus communication velocity across attached S700 I/O clusters. Its multi-signal density combines digital discrete logic and 12-bit analog loops into a single chassis footprint, optimizing cabinet I/O density scaling without auxiliary expanders. The module maintains full firmware flash compatibility, allowing seamless node address configuration and protocol synchronization when docked onto TU709F or TU710F terminal units.
Frequently Asked Questions
Q: Does the CI741F communication interface support hot-swap insertion during operation?
A: No. The CI741F does not support hot-swapping; power to the terminal unit base must be disconnected prior to removing or installing the module.
Q: Which terminal unit bases are compatible with the CI741F module?
A: The CI741F installs directly onto the ABB TU709F or TU710F terminal unit mounting bases.
Q: What signal types are supported on the integrated analog channels?
A: Analog inputs support +-10 V, 0/4-20 mA current loops, and RTD temperature sensors. Analog outputs provide configurable +-10 V or 0/4-20 mA control signals.
Field Installation Guidelines
Follow these technical procedures during panel installation and field wiring:
- Terminal Base Docking: Align the rear connector pins of the CI741F with the TU709F or TU710F terminal unit interface, pressing straight in until the locking side tabs engage.
- Ground & Shielding: Connect the PROFIBUS DP cable braid to the metallic shield clamp on the Sub-D connector shell to establish continuous low-impedance earthing.
- Field Bus Connection: Fasten the 9-pin Sub-D PROFIBUS cable plug onto the module port and secure the mounting thumb screws.
- Signal Cable Separation: Route low-level analog input cables and RTD wires in dedicated wire ducts isolated from high-voltage AC lines to eliminate signal interference.
