ABB S800 I/O Series
The ABB S800 I/O Series offers a modular, distributed I/O solution over PROFIBUS and Advant Fieldbus 100 (AF100), providing flexible communication with ABB drives. It supports both PROFIBUS-DP and PROFIBUS-DPV1 networks, ensuring versatility for various industrial applications.
Key Features
- Flexible Communication: Utilizes Advant Fieldbus 100 or PROFIBUS for external connections, with ModuleBus for internal links.
- Modular Configuration: Supports up to 24 I/O modules, with redundancy options for critical systems.
- LED Indicators: Provides visual feedback for system status (RUN, FAULT, WARNING).
- Cyclic Data Transfer: Transfers data cyclically with cycle times between 4-108 ms.
S800 I/O Station Configuration
-
Base Cluster:
Includes 1 (or 2 for redundancy) Fieldbus Communication Interface (FCI) and up to 12 I/O modules (or 6 pairs for redundancy). -
I/O Cluster:
Contains 1 optical ModuleBus modem and up to 12 I/O modules for modular expansion.
I/O Modules
The S800 I/O system offers various I/O modules, including analog, digital, RTD, and TC interfaces. Modules typically range from 2 to 16 channels, depending on type and rating. All modules are supervised for status checks during startup and operation.
-
Digital I/O Modules:
Feature galvanic isolation and LED indicators for channel status, along with error status for output modules and Intrinsic Safety interfaces. -
Field Power Monitoring:
Input modules monitor field power, and a loss of power triggers a warning status and error on the channel.
Communication Interfaces
-
PROFIBUS:
Connects directly to PROFIBUS-DP or PROFIBUS-DPV1 networks, functioning as a slave on the network. -
ModuleBus:
Handles internal communication between clusters and I/O modules for seamless data flow.
Hardware Components
Key components in the S800 I/O system include:
- I/O Modules
- Module Termination Units (MTUs)
- Fieldbus Communication Interface
- ModuleBus Items
These are mounted on DIN-rails (EN50022 NS 35/7.5) for easy integration.
Digital I/O Modules
- Galvanic Isolation: Ensures safety by isolating channels.
- Status Indicators: LED indicators for module and channel status.
- Field Power Monitoring: Indicates loss of field power and sets module status to warning with an error on the channel.
- Redundant I/O Options: Supports redundancy for high-reliability applications.
