Functional Overview
The IM ET08 serves as an Ethernet interface module for the H7-200 Smart series. It facilitates the communication of I/O data from expanded modules to a master station using the S7 slave protocol. The module supports integration with S7-200smart or H7-200smart series CPUs and can handle I/O data in various zones, including I zone, Q zone, AI zone, AQ zone, and V zone.
Key Features and Expansion
- Expansion Capability: Supports the connection of up to 6 smart expansion modules.
- Communication Protocol: Utilizes S7 slave protocol, allowing for easy integration with compatible master stations and CPUs.
- Compatible Modules: Supports all digital and analog expansion modules, including I/O modules that use V zone. DP01 modules are not supported.
- Convenience: Offers seamless integration with S7-200smart or H7-200smart series CPUs, enabling efficient communication and control of I/O data.
Supported Module Types
- Digital Modules: Supports various digital I/O modules.
- Analog Modules: Compatible with analog I/O modules.
- Modules using V Zone: Supported, allowing more flexible integration into systems.
- Exclusion: DP01 modules are not supported.
Isolation and Protection
- The module provides optical isolation for both the field and logic sides (500V AC for 1 minute) to protect sensitive components from electrical surges and noise.
