Phoenix Contact ILC 1X1 Field Troubleshooting and Engineering Application Guide

5.4 FTP Access Issues

Phenomenon: Unable to view SD card contents through FTP. Reason: The FTP server is not activated or access is restricted. Solution:

Enable FTP Folder View in Internet Explorer.

Control the FTP server through the CPU_Set_ValueRequest service in PC Worx (Var ID 0172hex, value 0001hex activated, 0000hex disabled).

The default username is anonymous, and the password is empty. To restrict access, you can use CPU_Set_ValueRequest() (Var ID 019Ahex) to set the username and password (in ASCII hexadecimal format).

Troubleshooting of PROFINET device functionality

ILC 1X1 can be used as a PROFINET device (slave) to access higher-level controllers (such as RFC 470 PN 3TX). The configuration steps are as follows:

Assign an IP address (such as 192.168.161.155) to ILC.

In PC Worx, open the controller "Extended Settings" ->select "PROFINET device activated" ->send and restart the controller.

Use the "Read PROFINET" function in the main station project to scan the network and read the device names and process data of ILC.

Common faults:

BF LED constantly on: No connection established with PROFINET controller. Check the switch and network cable to ensure that the device names configured in the main station are consistent with the names set in ILC (which can be modified through DCP).

SF LED constantly on: There is a diagnostic event (such as a fault in an input module). Read diagnostic data of ILC (via PND_S1 system variable).

Process data not updated: Confirm that the length of the process data configured by the main station matches the actual length of the ILC. When ILC is used as a PROFINET device, its IN/OUT process data length can be viewed in the "Process Data" tab.

Special cases of power and ground faults

7.1 All LEDs do not light up after power on

Reason: The external fuse is blown, the power supply is not connected, or the polarity is reversed. There is a polarity reversal protection diode inside the controller, but reversing it can cause a large current to flow through the diode and burn out the external fuse. Correct method: Measure the voltage at terminals 1.1 (+) and 1.3 (-), which should be between 19.2 and 30V.

7.2 FR and RDY do not flicker

Possible reasons: insufficient voltage of the UICC, damage to the internal firmware of the controller, or hardware malfunction. After attempting to power off, press and hold the reset button before powering on. If there is still no improvement, it is necessary to return to the factory for repair.

7.3 Output no voltage but E LED does not light up

Check if the US segment power supply is connected (terminals 1.1 and 2.3). If the US is normal, measure the voltage at the output point to SGND. If the load is inductive, confirm that the freewheeling diode has been installed.

Maintenance and firmware upgrade

8.1 Firmware Update

Firmware updates are only used to add new features and are not necessary. Update method: Use the dedicated tool provided by Phoenix Contact via Ethernet (see application instructions "Firmware update ILC 1.../3..."). Be sure to back up the project before updating.

Attention: After updating the firmware, all parameters and programs will be lost (unless stored in the main memory of the SD card). Save the project file before updating.

8.2 Real time clock battery

The standard model (non XC) has a built-in real-time clock, which is held by a capacitor for about 10 days after power failure (it takes 24 hours to fully charge). If time is lost after a long-term power outage, it needs to be resynchronized (which can be done through the SNTP function block). The XC model has no clock holding capacitor and must be synchronized through SNTP or PLC every time it is powered on.

8.3 Environment and Rating Reduction

When the ambient temperature exceeds 55 ℃, ILC 131/151/171/191 needs to be downgraded for use (see manual downgrade curve). The XC model is available within the temperature range of -40 ℃ to+60 ℃, but requires an additional derating (multiplied by a factor of 1.25) when the voltage exceeds 24.5V.

Typical troubleshooting process (pocket steps)

Visual inspection of LED: PWR LED (UL/UM/US) must be fully illuminated; FR should flash or stay on constantly; If FF is constantly on, there is an error when connecting PC Worx to read the runtime.

Check the power supply: Use a multimeter to measure the voltage and ripple (not exceeding ± 5%) of the UICC, UM, and US terminals.

Verify IP communication: Use the ping command to test the controller IP. If there is no response, reassign the IP through the serial port or DCP.

View diagnostic system variables: Read MASTER-DIAGVNet REG and MASTER-DIAG-PARM-REG in the application to obtain the location of the INTERBUS bus error.

Check SD card: If the program is lost, confirm whether the SD card is loose or damaged. Remove the SD card and restart to see if it has been restored to the internal flash program.

Restore factory settings: Use MRRESET or hide reset button to clear incorrect configurations.

Upgrade replacement and spare parts suggestions

When replacing the old ILC 1X1 controller (if the hardware version is lower than 004.00) with a new one, please note:
