Phoenix Contact ILC 1X1 Field Troubleshooting and Engineering Application Guide

3.2 IP Address Allocation Method

There are three ways:

BootP server (default mode): After the controller is powered on, it sends a BootP request broadcast. Activate the BootP server in PC Worx Express, enter the MAC address of the controller (printed on the side of the device, format 00.A0.45. xx. xx. xx) and assign an IP address. Once successful, the IP address will be permanently stored in the internal parameter memory.

DCP protocol (firmware ≥ 4.20 required): Set the IP and PROFINET device name directly in the device details window of PC Worx.

Serial port (only for IP allocation, non programmable): Use a COM CAB MINI DIN cable to connect the PC serial port to the controller PRG port (mini DIN), and set the IP through Diag+software.

Common malfunction: BootP allocation failure, message window shows no response. Check if the PC network card and controller are in the same physical network segment (not necessarily the same IP segment, but BootP is broadcasting and requires the switch to allow broadcasting), and also confirm that the MAC address input is correct.

3.3 Reset the controller through the mode switch

If you forget your IP or need to completely clear the program and retain data, you can use the MRESET function: turn the mode switch from STOP to MRESET position for 3 seconds, then release it (<3 seconds), and then turn it to MRESET position for 3 seconds. After completion, the controller returns to its factory state, the IP address is cleared, and the program is lost.

Hide reset button: Press and hold the reset button with a pointed object while turning off the power and then turning it back on. Wait for the FF (yellow) LED to flash before releasing it. After about 1 minute, FR and RDY will flash, indicating that it has been restored to the factory.

LED indicator light fault diagnosis

The ILC 1X1 provides rich status LEDs for quick identification of fault sources.

Common reasons and countermeasures for the meaning of LED color status

UL green out 24V UILC missing check power terminals 1.1/1.3, whether the voltage is 19.2~30V

UM green out 24V main power supply missing inspection terminal 2.1/2.2

Check for missing terminals 1.1/2.3 or external fuses in the 24V segment of the US green out power supply

FR green flashing system ready when running, stopped state with no program running or program stopped

FR green constant light program is running normally

FF yellow constant bright runtime error program includes zero division, array out of bounds, etc., PLC error variables need to be checked

RDY green flashing INTERBUS master station ready but not running waiting to start

FAIL Red Always On INTERBUS Bus Fault Remote bus disconnection, missing terminal module or hardware failure

The BSA yellow constant bright bus segment has been closed, and a remote bus branch has been disconnected

PF yellow constant bright peripheral device failure, a certain I/O module failure or parameterization error

E yellow constant light output short circuit/overload check Q1~Q4 load, eliminate short circuit

BF (PROFINET) is always red and there is no PROFINET connection. The controller has not established communication with the PROFINET controller

BF is flashing red and establishing a connection is normal

SF (PROFINET) is always red and on. PROFINET diagnostic information exists. View controller diagnostic data

On site case: A user reported that the controller RUN light is not on, FR is flashing, and FF is constantly on. Through PC Worx online reading of errors, it was found that the runtime overflow was caused by a short cycle time in the task configuration. Restore after modifying the task cycle.

SD card (parametric memory) usage and troubleshooting

All ILC 1X1 supports inserting SD cards (Phoenix Contact specific, pre formatted). SD cards can be used as main storage or additional storage.

5.1 Main Memory Mode

When the SD card is inserted before the controller is powered on and the PC Worx is set to "Preferable use external SD card as main memory" (default), all project data and IP configurations are stored on the SD card, and the internal flash memory is erased. When running in this mode, the SD card cannot be unplugged, otherwise it will cause the program to stop and report an error (FAIL LED on).

Attention: In the explosion-proof area (Zone 2), SD cards can only be used as main storage and are strictly prohibited from being plugged in or unplugged with power on.

5.2 Additional Memory Mode

If the SD card is inserted after the controller is started, or if it is set to "Use external SD card as additional memory" in PC Worx, the SD card is only used to store user files (such as logs and recipes), and the program still runs in internal flash memory. At this time, it is possible to insert/unplug during operation, but it is necessary to avoid unplugging during read and write operations.

Common error: After formatting the SD card to FAT32 on the PC and reinserting it, the controller cannot recognize it. Phoenix Contact's original pre formatted SD card (order number 2988146 or 2988162) must be used and cannot be formatted by oneself.

5.3 SD card as log storage

By accessing the controller through FTP (with FTP server enabled), folders (such as Logfile) can be created in the/sddisk directory. Then use the function blocks such as FILE. OPEN and FILE. WRITE in PC Worx to write runtime data to the SD card. Pay attention to the lifespan of write cycles (typically 100000 per sector) and avoid frequent writing of small data.
