Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The 2711-T5A10L1 functions within control architectures by providing deterministic operator feedback and command entry. While the unit utilizes DeviceNet for process data exchange, its integration into larger systems necessitates careful management of I/O density scaling to prevent network bandwidth saturation. Firmware flash compatibility is limited to the specific series architecture (A through H), and users must ensure that development software matches the terminal series to guarantee communication integrity. The terminal operates as a node on the DeviceNet network, requiring proper termination and bus power management to maintain deterministic response times.

Frequently Asked Questions

Q: Can the internal battery-backed Real Time Clock (RTC) be replaced?

A: Yes, the RTC battery is replaceable. It is recommended to perform this maintenance while the unit is powered to prevent loss of clock data and configuration parameters stored in the volatile memory.

Q: Is this terminal compatible with modern Ethernet-based PLC controllers?

A: The 2711-T5A10L1 is equipped with DeviceNet and RS-232 ports only. It does not possess native Ethernet connectivity. Integration with Ethernet-based controllers requires a protocol converter or a bridge module to translate DeviceNet data packets.

Field Installation Guidelines

1. Ensure the panel cutout dimensions are accurate to maintain the integrity of the enclosure seal; utilize the provided mounting gasket to achieve the required ingress protection rating.
2. Secure the terminal using the provided mounting clips, ensuring even torque distribution to prevent warping of the bezel or display housing.
3. Terminate the 24 VDC power supply to the input terminals, ensuring voltage remains within the 18-32 VDC range to avoid erratic touchscreen behavior or terminal resets.
4. If utilizing the RS-232 printer port, ensure the cable is shielded and grounded at one end only to mitigate electromagnetic interference (EMI).
5. Verify DeviceNet cable polarity and termination resistors (121 ohm) at both physical ends of the network trunk to ensure signal stability.
