Professional FAQ (Experience & Selection Guide)
- Q1: What is the maximum cable length between IM 460 and IM 461-3?
A: 102.25 meters. Use shielded twisted-pair cable and the correct termination plug to achieve this distance without signal degradation. - Q2: Can I use the IM 461-3 without the C-bus?
A: No. The IM 461-3 is designed for C-bus coupling. For standard bus, use the IM 461-0 variant. Check your CPU’s bus type before ordering. - Q3: What power supply rating do I need for the backplane?
A: The module draws 620mA from the 5V backplane bus. Ensure your S7-400 power supply (e.g., PS 407) has enough reserve for all installed modules. - Q4: Is the termination plug included with the module?
A: No. The termination plug is ordered separately as 6ES7461-3AA0-7AA1. It is mandatory for proper bus termination – do not omit it. - Q5: Which S7-400 CPUs work with the IM 461-3?
A: All S7-400 CPUs with an IM 460-3 sender interface. Commonly used with 416, 417, and 414 series. Verify your CPU’s interface module compatibility.
