Product Description:

The EL6632 is an application terminal for implementing EtherNet/IP communication within an EtherCAT system. It offers two channels of communication and connection to EtherNet/IP networks along with seamless operation within the EtherCAT system. The EL6632 is an EtherNet/IP slave interface that facilitates I/O data transfer via EtherNet/IP protocol-based controllers.

It is driven from a supply voltage of 24 V DC provided through the terminal bus within an acceptable tolerance of -15% to +20%. It can be operated in a stable state under various power levels. The terminal draws about 430 mA of power directly from the system E-bus. The EL6632 incorporates system voltage and Ethernet interface isolation internally to safeguard inner circuits from potential faults in the future and enable safe operation in electrically adverse industrial environments. Using long-term plastic casing, this terminal gives rugged performance. It guarantees long lifespan even in challenging environments. Further, the isolation feature enhances signal integrity and eliminates electrical interference. This is important when combining mixed-voltage systems. The two channels in this unit offer flexible communication environments. These can be utilized to give redundancy or enhance connection to several EtherNet/IP devices at the same time. It offers high-level network settings and allows effective data traffic between I/O modules and controllers. It is of compact size that is ideally suited for mounting on DIN rails, and it is simple to integrate with other Beckhoff terminals in a modular installation.

The EL6632 is particularly suitable for high-performance cross-network EtherCAT and EtherNet/IP domain communication applications. It facilitates control system interoperability, easy distributed device connection, and system design flexibility. The terminal's reliable communication, electrical protection, and compatibility make it an efficient device for connecting several industrial Ethernet-based systems in automation applications.

Symptom seen in TwinCAT / LEDs	Typical Cause	Recommended Fix / Next Step
PnIoError > 0 counter increments	One or more PROFINET devices could not establish a connection (wrong device type, powered-off node, wiring fault)	Verify power & cabling, then compare actual topology to the offline project; replace/renumber the offending node and reload configuration
PnIoDiag > 0 counter increments	At least one device has posted a PROFINET diagnosis (e.g., IP conflict, port alarm, module mismatch)	Open the diagnostic buffer for that device in TwinCAT, clear the alarm, and correct the underlying condition (IP, module order, etc.)
Terminal drops to SAFE-OP immediately after start	Controller’s real-time settings or PC jitter exceed PROFINET timing budget	Move runtime to a non-mobile CPU, tighten task cycle times, or increase IRT cycle time to regain OP state
Watchdog error in Box-States list	PROFINET watchdog timer expired—frames not received in time, often due to overloaded network or too-short cycle time	Lengthen cycle time or increase watchdog factor; check switches and replace any cabling with CRC errors
DataHold error reported	Data were invalid for longer than the DataHold timer allows (device stopped responding)	Inspect the offending device: verify firmware, power, and EM-noise shielding; restart node and controller
RTC3: Sync signal could not start	IRT sync (Sync0) missing or not forwarded to EL6632	Make sure the EtherCAT master produces Sync0, check distributed-clock settings, and verify correct cabling order
PROFINET Controller link error (link LED off)	No physical Ethernet link on Port 0/1, or duplex/speed mismatch	Check RJ45 plug seating, replace patch cord, verify port LEDs, and force 100 Mbit Full-Duplex on switches if needed
“Expected device not in projected position” message	VendorID/DeviceID mismatch—wrong device type or slot order in project	Insert the correct GSDML, drag the real device to the right slot in the I/O tree, and download the updated project
Startup halts until station name assignment; device shows “Not named”	PROFINET station name absent or spelled differently from project	Use Scan PNIO Devices → Set Device Name in TwinCAT to assign the exact project name, then reboot the device
WC-State of cyclic EtherCAT frame = 1 (gateway only)	EtherCAT Working-Counter error—EL6632 didn’t receive the expected frame acknowledgements	Check upstream EtherCAT slaves for lost frames, ground loops, or missing terminators; correct wiring, then restart scan

Model	Fieldbus / Interface	Role (Master vs. Slave)	Ports & Medium	Typical Max Nodes	Real-Time / Cycle Capability
EL6632	PROFINET IRT (Conformance Class C)	Controller (Master)	2 × RJ-45 100 Mb Tx	5 IRT / 15 RT	≥ 500 µs IRT, 1 ms RT
EL6631-0010	PROFINET RT (Class B)	Controller (Master)	2 × RJ-45 100 Mb Tx	15 RT	≥ 1 ms RT (non-isochronous)
EL6731	PROFIBUS-DP	Master	1 × D-sub 9 RS-485	125 slaves	12 Mb DP; optional isochronous axis mode
EL6751	CANopen	Master (can operate as slave)	1 × D-sub 9	127 nodes	Up to 1 Mb; event-driven PDOs
EL6652	EtherNet/IP™	Master / Scanner	2 × RJ-45 10/100 Mb	16 adapter devices per generic node	Implicit CIP, ≥ 1 ms cycles typical
EL6695	EtherCAT Bridge	Coupler between two EtherCAT strands	2 × EtherCAT IN/OUT	n/a (segment-to-segment)	up to 2 × 2048 B per cycle, DC sync both ways

Error name	Meaning / Typical cause & next step
No error	Normal operating state – nothing to do.
Device state-machine in boot mode	Controller is still starting; usually not a fault – wait until it reaches OP.
Device not found	Projected station doesn’t reply to Identify – check power, cabling, and station-name spelling.
DCP Set unsuccessful	Name/IP assignment via DCP failed – verify network topology and resolve duplicate names.
Watchdog error	PROFINET watchdog timer expired – lengthen cycle time or increase watchdog factor.
DataHold error	Cyclic data invalid longer than DataHold permits – inspect offending device, firmware, and wiring.
RTC3: Sync signal could not start	IRT Sync0 missing – check EtherCAT distributed-clock settings and cabling order.
Link error on controller	No physical Ethernet link on one/both ports – reseat or replace patch cords, verify LEDs.
Automatic name assignment impossible (wrong type)	VendorId/DeviceId mismatch – insert correct GSDML or move device to projected slot.
WC-State of cyclic EtherCAT frame = 1	Working-counter fault on upstream EtherCAT slaves – inspect wiring, terminators, and slave status.
