General FAQ Including Update Topic

Connection

Why can’t I connect the CPU in Control Expert?

Possible cause:

A BME XBE 1000 rack extender module may be installed on the main local rack without the presence of an extended local rack.

Possible solution:

Remove the BME XBE 1000 module from the main local rack, or add an extended local rack.

Why can’t I connect to the CPU with Unity Loader?

Possible cause:

By default, the service in the CPU is disabled (cyber security default setting). Unity Loader does not connect to the CPU if this service is disabled.

Possible solution:

Enable the FTP service in the CPU by downloading an application, in which the FTP service is enabled, to the CPU.

How can I update a BM• CRA 312 •0 (e)X80 EIO adapter module that is not yet configured?

The BM• CRA 312 •0 module receives its IP address from the CPU at startup. If the CPU is not configured or the firmware version of the BM• CRA 312 •0 module is not compatible, the BM• CRA 312 •0 module does not receive an IP address.

Set the rotary switches on the BM• CRA 312 •0 module to stored. Power cycle the BM• CRA 312 •0 module. Connect the BM• CRA 312 •0 module via its service port to Unity Loader using the IP address: 10.10.mac5.mac6.

ConneXium Network Manager

Why can’t I discover IMPRs? I installed the ConneXium Network Manager tool, but the IMPRs are shown as devices.

Possible cause:

You may not have the latest version of ConneXium Network Manager.
You may not have specified the GET community name while discovering the network.

Possible solution:

Install the latest version of ConneXium Network Manager or contact Schneider Electric support to get the Ethernet IMPR device types.
Add the GET community name of the IMPR before discovering the network. You can retrieve the GET community name by reading the configuration using PowerSuite. By default, the IMPR GET community name is public_1.

Why is ConneXium Network Manager taking such a long time to discover the network?

Possible cause:

The parameters you selected before discovering the network may be slowing down the process.

Possible solution:

You can speed up the network discovery by adjusting the tool discovery parameters. Please read the ConneXium Network Manager Ethernet Diagnostic Tool Reference Guide.

NOTE: If you increase the network discovery speed, you will also increase network traffic.

Why does ConneXium Network Manager display the IMPRs in a star topology when I have the IMPRs connected in a daisy chain or daisy chain loop topology?

Possible cause:

ConneXium Network Manager does not currently support daisy chain and daisy chain loop topologies. Please contact ConneXium Network Manager support to find out when these topologies will be supported.

Possible solution:

Manually edit the network topology that ConneXium Network Manager displays to create your own topology.

Why does ConneXium Network Manager say that my IP address has an invalid gateway?

Possible cause:

When you enter a gateway address, ConneXium Network Manager does 2 things:

validates that the gateway address is in the same subnet as the IP address
contacts the gateway address
- If a response is received from the gateway address, ConneXium Network Manager discovers if the address is actually a gateway/router address. If the address is not an actual gateway/router address, ConneXium Network Manager displays a detected error message.
- If no response is received from the gateway address, ConneXium Network Manager takes no action.

Possible solution:

Enter a valid gateway address.

– or –
Enter a gateway address that is in the same subnet as the IP address. Check that the gateway address is not assigned to any other device on the subnet.

CPU

How do I proceed when a CPU, whose ERR, I/O, and BACKUP LED indicators are red, has stopped communicating?

The configuration memory in the CPU may be corrupted, which is detected during self-tests, and may not allow the CPU to boot. Move the CPU to another rack slot and power cycle. The CPU will then start in no conf state.

How do I set my CPU to a no conf state?

Use the backup clear feature in Control Expert, and power cycle the CPU.

Ethernet Ports / Cables / Networks (Loops)

Why is my Ethernet device (HART module, weighing module, or distributed device) unable to accept its configuration?

The FTP and services are disabled (cyber security default setting). In your application, enable FTP or TFTP, if your security policy allows.

When you have an Ethernet device that uses and you want to disable FTP, follow these steps:

Enable FTP in your application.
Invoke the ETH_PORT_CTRL EFB (EthPort_Control_MX function for Unity Pro V8.0 projects) to disable FTP after the devices have accepted their configuration.
To temporarily enable FTP to replace a non-communicating device, invoke the ETH_PORT_CTRL EFB (EthPort_Control_MX function for Unity Pro V8.0 projects).

Can I connect a PC to an RIO module port?

Yes, but PCs are not be able to communicate with any modules. We recommend you connect PCs (or any other non-RIO device) to these:

Connection	Port
DRS	DIO Cloud or DIO Sub Ring port
CPU	SERVICE port (configured as an access port)
BMENOS0300	DIO or SERVICE port
BM•CRA312•0 X80 EIO adapter module	SERVICE port (configured as an access port)

Function Blocks

Why aren’t the PRINT_CHAR_QX and INPUT_CHAR_QX function blocks working with my Unity Pro 7.0 application, after I updated (or replaced) the BMX CRA 312 •0 X80 EIO adapter module?

The firmware in the BMX CRA 312 •0 module has evolved to increase its robustness. This evolution is not compatible with the PRINT_CHAR_QX and INPUT_CHAR_QX function blocks in Unity Pro 7.0.

Perform one of the following to make these function blocks operate:

Migrate the application to Unity Pro 8.x.

– or –
Downgrade the BMX CRA 312 •0 module to version 1.30.

IP Addressing / FDR

Can I use the stored and clear IP rotary switch positions on the BM• CRA 312 •0 X80 EIO adapter modules?

We recommend that you do not use these switch positions on the rotary switches because they do not support I/O module management. The only way to manage I/O modules is to use the ones and tens positions.

IPsec

For questions regarding , refer to BMENOC0301/11 guide.

Remote I/O

What happens if I measure an application response time () that is higher than I expected?

If the is cyclic, the default is set to 60 ms. If the actual execution time of the MAST task is lower than 120 ms, the ART is affected by the RPI.

Adjust the RPI value to your needs, or set your MAST task in periodic mode.

Time

How can I display the local time when %MW49...53 seem to be in ?

The words %MW49...53 are in universal coordinated time (UTC), not in local time. If you require local time, use the RRTC_DT function block. (NOTE: RRTC_DT_MS is also in UTC time.)

Topologies

Do we have to follow the topology rules given in the user guide?

Yes, the system has been tested with the topology rules provided. The level of and the operating characteristics of the network described in this document are based on a system designed according to these rules.

Can I connect DIO scanner devices (M340, Premium) to DIO ports or clouds or in a DIO network?

We recommend that you do not add these devices to DIO ports. Each DIO port on / BM•CRA312•0 X80 EIO adapter modules has a bandwidth that determines how much traffic is allowed on the M580 main ring. This bandwidth limitation can cause DIO scanner performance to decrease, which may be unacceptable in your network.

What type of distributed equipment can I connect to DIO ports or clouds?

You can connect devices that do not support 802.1D/Q tagging.

Example: Advantys, TeSyS-T, Momentum, and non-Schneider devices

Can I access devices (via ping, PC tools) in an M580 network via the SERVICE port (ETH1) when it is configured in port mirror mode?

No. When the SERVICE port is configured in port mirror mode, you cannot access devices, that is, you cannot ping other devices by connecting a PC to ETH1 in port mirror mode. When the SERVICE port is configured in access mode, then you can access devices in an M580 network via any tool.

Unity Loader

What is the correct procedure to update the BME NOC 03•0 Ethernet communication module?

Update the BME NOC 03•0 module by connecting Unity Loader to the Ethernet port of the BME NOC 03•0 module. The connection can be direct or via a dual-ring switch ().

You cannot use the USB port of the CPU to access the BME NOC 03•0 module. The following message appears: “Upgrade error: Com = CallBack (on channel 10 index 0 and channel 10 index 5).”

Can I update the CPU’s firmware via the BME NOC 03•0 module?

Yes, you can connect the BME NOC 03•0 module’s embedded Ethernet switch to the CPU. Check that the BME NOC 03•0 module is running properly before starting the update procedure.

You cannot, however, update the CPU if Unity Loader is connected on the BME NOC 03•0 module’s IP address.

Control Expert

The IP address field in Control Expert is grayed out. How can I modify this field?

Remove your application from the virtual connected mode to edit the IP address field.

USB

Why am I unable to connect to the CPU via the USB port?

Possible cause:

You may have connected the PC to the CPU before installing the USB driver. On a PC running Windows®, install the driver before connecting your PC to the CPU. Otherwise, Windows® installs a default deriver that does not match the CPU requirements.

Possible solution:

In Windows® configuration panel, uninstall the driver attached to the CPU.
Install the driver (from the driver DVD, the Control Expert DVD, or the Unity Loader DVD).
Reconnect the USB cable between the CPU and the PC.

Web

Why are the CPU webpages not displaying properly?

Possible cause:

The CPU webpages are designed to work with Internet Explorer 8 configured in standard mode. The pages do not display properly when configured in Internet Explorer 7 compatibility mode.

Possible solution:

Configure your Internet Explorer to work in Internet Explorer 8 standard mode

In Internet Explorer, click Tools → Developer Tools → Browser Mode: IE8 → Internet Explorer 8 Compatibility View
In Internet Explorer, click Tools → Developer Tools → Document Mode: IE8 Standards → Internet Explorer 8 Standards
