Product Description
The ALP111‑S00 is a PROFIBUS‑DP communication module made by Yokogawa designed to act as a communication master on a PROFIBUS‑DP network. It enables the field control unit (FCU) or bus node to communicate with slave devices over the PROFIBUS‑DP protocol. The module includes an isolated interface, RS‑485 physical signaling, support for a maintenance port (RS‑232C), and supports data rates up to 12 Mbps. It works in industrial ambient conditions, and is used in control architectures where PROFIBUS is adopted for deterministic, high‑speed communication with distributed devices.
It is mounted in racks or node units (like ANB10, ANB11, etc.), and has built‑in features for diagnostics, isolation, and standard termination practices for PROFIBUS segments. The ALP111‑S00 thus serves as a bridge / gateway / master communications card for the fieldbus layer.
Applications
-
PROFIBUS‑DP networks in industrial plants (chemicals, oil & gas, power, water/waste) for controlling / communicating with distributed I/O, actuators, sensors, valves.
-
Master communications in bus node units: field control units, remote IO racks.
-
Sectors where reliable industrial data communication is required with multiple slave devices.
-
Where isolated interface and long cable distances are needed.
-
Installations with diagnostic / maintenance constraints: ability to use maintenance port, detect failures, etc.
Advantages
-
Wide speed range up to 12 Mbps gives flexibility for various application sizes.
-
Isolated communication port increases robustness and safety (less risk from electrical noise or ground faults).
-
Maintenance port (RS‑232C) allows configuration / troubleshooting without disrupting main bus.
-
Moderate size and weight make it feasible to retrofit in existing racks / bus‑node units.
-
Standards compliance (PROFIBUS DP‑V0 etc) ensures interoperability.
-
Diagnostics and testability built in, helping reduce downtime.

Frequently Asked Questions (QA)
Q1: What is the supply voltage required by ALP111‑S00?
A1: The module requires approximately 24 V DC supply.
Q2: What is the operating temperature range?
A2: Rated for −10 °C to +60 °C in normal operation.
Q3: What is the weight and physical size of the module?
A3: Weight is about 0.30 kg. Dimensions are approximately 45 mm (W) × 97 mm (H) × 103 mm (D).
Q4: Which communication protocols does it support?
A4: It supports PROFIBUS‑DP (as master), using RS‑485 physical layer. It also includes a maintenance RS‑232C port.
Q5: What are the data rate / transmission speed options?
A5: From 9,600 bps up to 12 Mbps over PROFIBUS‑DP.
Q6: How far can one PROFIBUS segment go with this module?
A6: Up to 1.2 km for a segment when using lower data rates (like 9,600 bps). At higher speeds, distance will be shorter per PROFIBUS standards.
Q7: Does ALP111‑S00 have isolation?
A7: Yes. The communication interface (PROFIBUS port) is isolated from the internal power/logic, which protects against electrical noise and ground loop issues.
Q8: Is there diagnostic or maintenance support?
