Isolate all Input/Output connections. WARNING: The connecting leads may be connected to supplies. Isolate before touching.

Step 4: Open Rotating Covers

Open the rotating covers on the unit.

Step 5: Disconnect I/O

Disconnect all Input/Output connections. Leave Power, Ethernet, Current loop Lan, USB, RS232, and MS/TP connected (where appropriate).

Step 6: Record Serial Number and Location

Record the serial number and location of the unit for future reference. This information is typically found on a label on the unit.

Step 7: Select Terminator Switch Position (IQ4NC using MS/TP network only)

For IQ4NC units on an MS/TP network, ensure the terminator switch is set correctly. Refer to IQ422, IQ4NC Installation Instructions - Mounting (TG201264) for details of terminator use. The switch can be set to 'Terminator in circuit' or 'Terminator out of circuit'.

Step 8: Connect PC / Laptop

Connect your PC or Laptop to the IQ4NC/IQ422 either via an Ethernet Hub/Switch or using a direct connection. For direct connection, a standard Ethernet cable is used. For hub/switch connection, a standard Ethernet cable (Cat 5e twisted pair, max 100m) is used. Note: To connect with SET, a vCNC is required. SET can connect when on a different subnet. Other connection methods are detailed in the 'Connect to IQ4' section.

Step 9: Close Rotating Covers

Close the rotating covers on the unit.

Step 10: Switch On

Switch the unit on. The unit will perform a self-test, indicated by LEDs illuminating for several seconds.

Step 11: Check Watchdog/Power LEDs

Normal operation indication: Watchdog LED should be ON, and the Input power supply LED should be ON.

Fault indications: If the Watchdog LED is OFF or flashing, the device may be faulty or require a reset to defaults. If the Input power supply LED is OFF, check the input power supply.

Note: All LEDs illuminate for several seconds after switch on.

Step 12: Check Ethernet LEDs (if Ethernet is connected)

Normal operation indication: The OK LED (green) and RX LED (yellow) should illuminate.

Fault indications: If the OK LED is OFF, check the Ethernet connection. If the RX LED is OFF, check the Ethernet connection.

Note: All LEDs illuminate for several seconds after switch on.

Step 13: Connect to IQ4NC, IQ422 Using SET / IP Tool

Find the IQ4NC, IQ422 by its MAC address shown on the serial label. Use the SET software or the IP Tool software for configuration. Refer to the SET Manual (TE200147) and IP Tool Manual (TE200638).

The IP Tool interface displays device information such as MAC address, IP address, subnet mask, and device mode. You can configure settings like device mode (Auto-ip-DHCP or Auto-ip-switch), IP address, subnet mask, default router, and WINS server.

Step 14: Set up IP Addressing Details (if using Ethernet)

Use IP Tool to choose either static (fixed) or dynamic (DHCP) addressing.

Dynamic (DHCP) Addressing (default):

When set to dynamic (DHCP) addressing, the unit automatically obtains its IP addressing details from the network's DHCP server. If no DHCP server is found, the unit defaults to link/local mode.

Static (Fixed) Addressing:

When set to static (fixed) addressing, the IP addressing details must be configured manually. If email alarms are being sent, and the email server address is identified by internet domain name, then a DNS server must also be specified.

Step 15: Set up Virtual CNC (if required)

A Virtual CNC must be set up if connection to a supervisor, tool or display is required. Use IP Tool to set up the address and port number of the vCNC. IQ4NCs have 4 vCNCs enabled by default; IQ422s do not have any vCNCs enabled.

Step 16: Set up IQ4NC Communication Mode (if using IQ4NC)

Connect a PC directly to the IQ4 using an Ethernet cable. Access the controller's web pages via a web browser and select Modules > Networks to display the NC Configuration Wizard. Choose the desired network configuration (e.g., Ethernet Internetwork to MS/TP Lan, Ethernet Internetwork to Current Loop Lan, etc.). Refer to the IQ Web User Guide (TC201256).

Note: The IQ4NC has a Lan to connect to the internetwork and cannot join another Lan on the internetwork.

Step 17: Check Trend Current Loop Network (if current loop network being used)

Normal operation indication: TX LED (yellow) and RX LED (yellow) should be ON.

Fault indications: Check previous device on network (RX), check next device on network (TX), or set baud rate manually if TX/RX flashes for more than 30s.

Note: All LEDs illuminate for several seconds after switch on.

Step 18: Check MS/TP Network (If IQ4NC using MS/TP network)

Normal operation indication: TX LED (yellow) and RX LED (yellow) should be ON.

Fault indications: Check MS/TP connection and baud rate (RX, TX).

Step 19: Set up Ethernet Access Across Routers (if required)

If the LAN is to be built across routers, specify details of devices on each subnet in the Remote Trend Devices list using IP Tool. It is recommended that at least two devices from each subnet are specified. Ticking the checkbox next to the list retains it in IP Tool for easy copying to other devices.

Step 20: Set up Trend Addressing

Lan of IQ4s on current loop: Run SET, right-click the Lan of IQ4s in the System View, select 'Address IQ4 Device' to run the IQTool Addresser Applet. Use 'Automatic Discovery' or 'Manual Discovery'.

Single IQ4 or Lan of IQ4s on Ethernet: Use IP Tool to set the address (ensuring it is unique on the Lan) and Lan number.

Lan of IQ4 and pre IQ4 controllers on current loop: Run SET, right-click the Lan of IQ4s in the System View and select 'Address IQ4 Device'. Add the IQ4 to the grid manually by specifying the serial number and address.

Note: IQ4s are given a factory address and Lan number. Changing these may require resetting the IQ4.

Step 21: Write Details on Label

Record the unit's details, including MAC Address, Part No., and IP Address (or Hostname if DHCP), on the provided label.

Step 22: Set up Baud Rate (current loop network of IQ4s only)

Set one IQ4 to a specific baud rate using SET's IQTool Monitor Applet to ensure other IQ4s select the required rate. Autobaud can be disabled.

Step 23: Set up Additional Trend Addressing (if required)

Set the Supervisor Port or USB Engineering Port using SET's IQTool Monitor Applet if the controller needs to provide connection to the network for supervisors and tools.

Step 24: Check LAN OK LED (not IQ4NC)

Normal operation indication: LAN OK LED is ON ('Lan built OK' or 'Attempting to build Lan').

Fault indication: If the LAN OK LED is OFF, the device is faulty. If it flashes for longer than 2 minutes, the Lan/internetwork cannot be built. Check baud settings and connections. If it remains OFF after switching on other devices, check network cabling.

Note: It is normal for the Lan OK LED to extinguish for up to 1 min after detecting baud rate, then illuminate.

Step 25: Download Strategy

Configure the strategy using SET and test using SET's simulation mode. Use SET to download the strategy and backdrop file. An Ethernet connection is required for backdrop file downloads. Strategy download is not recommended over current loop with baud rate <9k6. SET will set the controller's date and time to that of the PC during download.

Step 26: Check IQ422 or IQ4NC on BACnet (If /BAC or IQ4NC and BACnet protocol communications required)

Use SET to check that IQ4's BACnet functionality is operating correctly by verifying its presence in the System View on its BACnet network.

Step 27: Test Inputs (Not IQ4NC/.../00)

Follow the sequence: Switch off, Open covers, Re-connect inputs, Close covers, Switch on. Verify correct operation.

Step 28: Test Outputs (Not IQ4NC/.../00)

Follow the sequence: Switch off, Open covers, Re-connect outputs, Close covers, Switch on. Verify correct operation.

Step 29: Connect Supervisors/Tools/Display Panels

Connect PCs for supervisors, tools, and displays as described in 'Connect to IQ4'. Connections can be made directly to the controller via RS232 Local Supervisor Port, USB Local Engineering Port, or Ethernet port, or over the Trend network.

Step 30: Backup Strategy

Use SET to upload the strategy and compare it with the strategy held by SET. An Ethernet connection is required for uploading strategy and backdrop files.
