Product Description

Description

Engineered for high-speed pulse processing in decentralized automation setups, the Beckhoff IP1502-B800 serves as a robust 2-channel counter module within the Fieldbus Box architecture. This dust- and water-tight field I/O unit integrates two independent 32-bit counters capable of handling pulse frequencies up to 100 kHz, making it suitable for rotational speed measurement, length acquisition, and positioning tasks directly in harsh field environments. Utilizing an RS485 transmission medium, this device communicates via a documented open serial protocol, enabling reliable integration into distributed control systems without requiring an additional protective enclosure.

Features

  • Dual High-Speed Counters: Two independent 32-bit counters with a maximum input frequency of 100 kHz.
  • Versatile Inputs: Incorporates 2 counter inputs, 2 gate inputs, and 2 up/down switches for directional counting.
  • Integrated Outputs: Features 2 short-circuit-proof 24 V DC outputs rated at 0.5 A for direct actuator control.
  • Rugged Fieldbus Box Design: Fully encapsulated IP67-rated housing for direct on-machine mounting without control cabinets.
  • RS485 Communication: Uses shielded copper cabling supporting variable transmission speeds up to 38.4 kbaud over distances up to 1200 meters.
  • Flexible Configuration: Configurable parameters, parameters, and operation modes via the Beckhoff KS2000 software tool.

Applications

  • High-speed pulse acquisition for industrial flowmeters and encoder tracking.
  • Decentralized positioning and length measurement in woodworking and metalworking machinery.
  • Rotational speed (RPM) monitoring in wind power plants and heavy-duty conveyor systems.
  • In-line parts counting and packaging line synchronization.

Empirical Engineering Insights

Alternative Models & Compatibility

The B800 series utilizes Beckhoff's proprietary RS485 serial fieldbus protocol. It is primarily compatible with serial coupling networks like the IPxxxx-B800 and IL230x-B800 couplers. If migrating to modern protocols such as EtherCAT or PROFINET, equivalent units from the EP series (such as the EP1518 or EP5101) should be evaluated. Ensure your master controller has the correct serial interface card configured to parse the 80-bit process image (comprising 2 x 32-bit counter values along with control/status words).

Application Pitfalls & Engineering Notes

When operating at the maximum frequency of 100 kHz, ensure that signal cabling is strictly shielded and kept separate from high-power motor lines. Standard M12 unshielded cables can pick up inductive noise, causing false pulse increments. Also note that up/down switching logic relies on a hardware signal that has a reduced frequency threshold of 2 kHz; attempting to toggle direction faster than this rate can lead to mismatched positional register counts.

Commissioning & Wiring Tips

Always configure the serial communication baud rate via the KS2000 software before deployment. The default baud rate is set to 38.4 kbaud. When daisy-chaining multiple boxes along the RS485 bus, a termination resistor (120 Ohm) must be placed at the final physical node on the network to prevent transmission reflections, especially over long cable runs exceeding 100 meters.

Installation Guidelines

CRITICAL WARNING

Disconnect all power sources (control voltage Us and load voltage Up) before installing or disconnecting M8 and M12 connectors. Operating connections under load can cause electrical arcing, damage high-sensitivity internal counter components, and compromise the unit's ingress protection.

1

Mount the Fieldbus Box using the 2 integrated 3.5 mm mounting holes with M3 hardware. Ensure the mounting surface is flat to prevent torque stress on the polyamide housing.

2

Tighten all mating M12 and M8 cable connectors to the specified torque values (0.6 Nm for M12, 0.4 Nm for M8) to guarantee an IP67 liquid-tight seal.

3

Apply 24 V DC to the M8 power feed port and verify status LEDs illuminate, confirming the internal control circuitry is active prior to initiating serial communication.

FAQ
What is the maximum pulse counting frequency supported by the IP1502-B800?
The module supports counter frequencies up to 100 kHz for high-speed pulse processing. However, if using the hardware up/down direction switching, the frequency limit for directional shifts is capped at 2 kHz.
Does this module require a physical mounting cabinet?
No, with its fully encapsulated polyamide housing and IP65/66/67 ratings, the unit is engineered for direct on-machine mounting without the need for an additional protective enclosure.
How are the serial communication parameters configured on this Fieldbus Box?
Baud rate, data formats, and module-specific configurations are set using the standard Beckhoff KS2000 software tool via the interface connection.
Are the digital outputs on the IP1502-B800 protected against short-circuits?
Yes, both 24 V DC, 0.5 A digital outputs, as well as the auxiliary sensor supply, are individually and fully protected against short-circuits.
