Description
- ABB PFSK152 communication module: This is a module used for industrial automation applications. It provides a way for devices to communicate with each other using the Phase-Shift Keying (PSK) modulation technique with a baud rate of 152 kbps.
- ABB PFSK152 communication protocol: This is a specific protocol used by ABB devices to communicate with each other. It is based on the PFSK modulation technique and is used in a variety of ABB products, such as drives, PLCs, and motor controllers.
- ABB PFSK152 communication interface: This is a more general term that could refer to any type of interface used by ABB devices to communicate with each other using PFSK modulation.
Details
PROFIBUS DP is a high speed multipurpose bus protocol (up to 12Mbit/s) for interconnecting field devices, like remote I/O, drives, low voltage electrical equipment, and controllers. PROFIBUS DP can be connected to the AC 800M via the CI854AK01 communication interface. The Classic CI854A includes two PROFIBUS ports to realize line redundancy and it also supports PROFIBUS master redundancy. The CI854B is the new PROFIBUS-DP master that replaces CI854A in new installations.
Master redundancy is supported in PROFIBUS-DP communication by using two CI854A communication interface modules. The master redundancy can be combined with CPU redundancy and CEXbus redundancy (BC810). The modules are mounted on a DIN rail and interface directly with the S800 I/O system, and other I/O systems as well, including all PROFIBUS DP/DP-V1 and FOUNDATION Fieldbus proficient systems.
The PROFIBUS DP must be terminated at the two outermost nodes. This is usually done by using connectors with built-in termination. To guarantee a correct working termination the connector has to be plugged and power supplied.
Features and benefits
- Used for connecting remote I/O and fieldbus instruments via PROFIBUS DP
- Possible to connect PROFIBUS PA to the CI854A/ CI854B via the PROFIBUS linking device LD 800P
- The CI854A and newer CI854B can be set redundant
