• Memory: 12 MB configuration memory, 2 SD card slots.

The backlight MTBF of 80 000 hours at 25 °C reduces maintenance frequency, while the dimmable backlight (0–100%) helps extend display life in continuous operation.

How Does This unit Handle Harsh Conditions?

Oil and gas sites demand rugged hardware. This panel's aluminum front and IP65 rating protect against dust and water ingress. The operating temperature range of 0 °C to 50 °C suits most indoor installations, and storage from -20 °C to 60 °C ensures resilience during transport.

For hazardous areas, ATEX and IECEx Zone 2/22 certifications allow deployment in classified locations. Marine approvals from GL, ABS, BV, DNV, LRS, and Class NK further validate its use on offshore platforms.

Integration and Communication

The TP700 Comfort connects seamlessly to Siemens S7-1200, S7-1500, S7-300/400, and even Allen Bradley and Modicon controllers via EtherNet/IP, Modbus, and OPC UA. The dual-port PROFINET switch enables daisy-chain wiring, reducing cabling costs.

Configuration is done with WinCC Comfort V11 or later, and the panel supports 32 online languages. For HMI touchscreen replacement projects, this model offers a straightforward migration path from older panels.

Maintenance and Serviceability

Designed for ease of service, the panel features a front-mounted design with a 198 x 142 mm cutout. The backlight is dimmable and rated for 80 000 hours, minimizing replacements. Two SD card slots and USB ports simplify backup and restore.

Periodic inspection of the front seal and cleaning with a soft cloth will maintain the IP65 rating. Always follow the manufacturer's safety manual for maintenance in hazardous areas.
