Description
Product Introduction
The ABB CP435-T-ETH (1SBP260197R1001) is a 7-inch widescreen graphic HMI panel from ABB’s CP400 hardware family. Engineered to provide local visualization and machine control, it features an 800 x 480 pixel CCFL-backlit TFT display capable of rendering 64,000 colors alongside custom function keys for rapid operator navigation.
Configured using ABB’s CP400Soft software, the CP435-T-ETH bridges field controllers to human operators. With its built-in RJ45 10/100 Ethernet port and dual serial communication channels (supporting Modbus RTU/ASCII and multiple PLC drivers), it is widely deployed in water treatment, packaging lines, power generation drops, and general factory automation.

Application Scenarios & The “Trench” Experience
A food processing facility in Wisconsin experienced a touchscreen failure on a secondary packaging machine when fluid ingress compromised the front membrane of an older HMI. The machine dropped off the factory Ethernet bus, stalling the downstream palletizer. After cutting power, the maintenance technician swapped in a replacement CP435-T-ETH, transferred the project file via CP400Soft over Ethernet, and torqued the front-panel mounting clamps into place. The new panel established communication with the AC500 PLC in minutes, resuming full line automation without requiring enclosure modifications.
- Manufacturing & OEM Machinery: Acts as the primary machine-side interface for custom skid controls, packaging units, and conveyor systems.
- Water & Wastewater Treatment: Displays real-time flow trends, pump station alarms, and PID loop values linked via Modbus TCP.
- Energy & Power Infrastructure: Provides local monitoring inside distributed turbine, boiler, and generator control panels.
Transparency SOP: Quality Assurance & Testing
Every CP435-T-ETH panel undergoes systematic quality screening prior to ESD-safe packaging:
- Visual & Gasket Inspection: The front IP65 sealing membrane, mounting latches, display glass, and rear terminal blocks are thoroughly inspected for wear or physical damage.
- Touch Matrix & Calibration Test: Power is applied (24V DC) to test multi-point touch calibration across all display zones and confirm keypress responsiveness on function keys.
- Display & Backlight Burn-In: The CCFL backlight and LCD array are checked for dead pixels, uniform brightness, and proper color rendering.
- Ethernet & Serial Handshake: Both the RJ45 Ethernet port and RS232/RS485 DB-connectors are wired to an AC500 test PLC to confirm project download integrity and cyclic data polling.
- Clean & Anti-Static Sealing: Panel faces are cleaned with screen-safe solvents, enclosed in thick static-shielding bags, and sealed with fresh desiccant packings.

The Veteran’s Tech Trap Guide (Crucial Value-Add)
⚠️ Backup Battery for RAM Data: The relies on an internal lithium button cell battery to preserve real-time clock (RTC) data and volatile RAM memory during power loss. If installing a spare unit that has been stored long-term, check or replace the onboard battery prior to commission to avoid losing runtime alarm histories or recipe offsets.
❗ Dip Switch & RS485 Termination Settings: The rear of the panel contains DIP switches used for setting internal serial line termination resistors. When connecting via RS485 multi-drop, ensure the termination switch is toggled ON only if the HMI is the physical first or last device on the daisy chain; leaving it incorrect causes intermittent frame drops.
⚠️ Gasket Sealing & Panel Cutout: To maintain its IP65 / NEMA 4X front-panel ingress rating, ensure the panel cutout dimensions (~231mm x 176mm bezel) are clean and flat. Over-tightening the mounting clamps can warp the plastic bezel, ruining the liquid seal and inviting moisture into the cabinet.
Frequently Asked Questions (FAQ for Conversion)
Q: Which programming software is used for the ?
A: Applications for the are designed and downloaded using ABB’s CP400Soft software suite.
Q: Can the communicate with non-ABB PLCs?
A: Yes. In addition to ABB AC500 controllers, the supports multiple fieldbus protocols including Modbus RTU, Modbus TCP, Modbus ASCII, and third-party drivers (such as Modicon, Siemens, and Allen-Bradley serial/Ethernet protocols).
Q: Is the still actively manufactured by ABB?
A: No. The CP400 series (including the ) is in legacy/discontinued status. Supplies are available primarily through certified New Surplus inventory and reconditioned stock.
Q: What is the difference between and ?
A: The “ETH” suffix denotes the integrated 10/100 Mbps Ethernet port. Standard non-ETH models rely exclusively on serial interfaces (COM1/COM2/COM3) for controller communications.
Q: What warranty is provided with this unit?
A: All (1SBP260197R1001) modules—whether New Surplus or Bench-Tested Refurbished—come with a full 12-month advance replacement warranty.
