ABB CPU Terminal base AC500 slot module TB511-ETH

ABB CPU Terminal base TB511-ETH

The ABB TB511-ETH (Part Number: 1SAP111100R0270) is a Terminal Base designed for use with the ABB AC500 V2 PLC (Programmable Logic Controller) system. Its primary function is to serve as the mounting and interface platform for the CPU module, providing essential communication ports and a slot for additional functionality.

Integrated Communication Interfaces

• Ethernet: It includes a dedicated ABB Ethernet (RJ45) interface, enabling the CPU to communicate using standard protocols like Ethernet TCP/IP and Modbus TCP for programming, visualization (HMI/SCADA), and networking.
• Serial Interfaces:
  • Two serial interfaces (RS232/RS485).
  • Communication with other devices using protocols like Modbus RTU or ASCII.

Communication Module Slot

• The ABB PLC TB511-ETH features one slot for mounting an optional Communication Module (CM). This allows users to extend the CPU’s connectivity to various fieldbuses, such as PROFIBUS, CANopen, DeviceNet, or additional Ethernet ports, without changing the core CPU itself.
