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?

A8: Yes. There is a maintenance port (RS‑232C), and many versions include diagnostic feedback or status indicators to aid troubleshooting.

Q9: What device mounting units is this module compatible with?

A9: It can be mounted in Yokogawa bus‑node units such as ANB10, ANB11, AFF50, AFV10, etc.

Q10: Is ALP111‑S00 certified according to PROFIBUS standards?

A10: Yes, it is certified to PROFIBUS DP‑V0 specification, meaning it meets Slave/Master requirements for PROFIBUS‑DP V0 interoperation.
