PROFIBUS DP-V1 and S800 Bus Communication Characteristics

The CI801-eA operates as a PROFIBUS FCI (Fieldbus Communication Interface) module within the ABB S800 I/O architecture. It manages cyclic and acyclic communication between PROFIBUS DP-V1 networks and connected S800 I/O modules.

Furthermore, the interface module supports ModuleBus communication for local I/O expansion. The included TB807 ModuleBus Terminator maintains the required bus termination condition for the S800 configuration.

The ABB industrial control platform uses structured backplane communication methods, and the CI801-eA supports I/O density scaling through connection of multiple S800 I/O units. Therefore, correct ModuleBus addressing, connector installation, and firmware compatibility must be verified during system configuration.

Frequently Asked Questions

Q: What communication protocol does the CI801-eA support?
A: The CI801-eA supports PROFIBUS DP-V1 communication as the fieldbus interface for ABB S800 I/O systems.

Q: What accessories are supplied with the CI801-eA?
A: The module package includes one power supply connector and one TB807 ModuleBus Terminator.

Q: Can the CI801-eA be installed without ModuleBus termination?
A: The ModuleBus network requires correct termination. The supplied TB807 terminator should be installed according to the S800 I/O system configuration requirements.

Field Installation Guidelines

• Install the CI801-eA on the designated ABB S800 I/O mounting position according to system hardware documentation.
• Verify PROFIBUS cable routing and maintain separation from high-voltage power cables to reduce electromagnetic interference.
• Connect the protective shield according to the plant grounding standard and PROFIBUS installation practice.
• Confirm ModuleBus termination using the supplied TB807 component before system commissioning.
• Check connector seating and power supply wiring before applying system voltage.
• Verify controller configuration, PROFIBUS node addressing, and communication diagnostics after installation.
