1.6 Compatibility
1.6.1 Signal types, building automation and control systems
This document describes the full functionality of the TX-I/O module system.
Depending on the building automation and control system not all functions are
supported, especially when the integration is made via a bus interface module.
• P-Bus BIM designates functions / restrictions that are valid for integration via P-bus
BIM (Desigo V2.37 and later).
• PROFINET BIM designates functions / restrictions that are valid for integration via
PROFINET BIM (Simatic S7 300/ 400).
• TRA: Desigo Room Automation (Desigo TRA).
 These functions are only supported by TX-I/O modules from series D.
The following table shows the support and designation of signal types in different
building automation and control systems. Gray = not supported / partially supported.
