Issue Does the Niagara R2 Modbus driver support a 6-digit address format? Product Line TAC IA Series Environment Niagara R2 Modbus driver Cause Modbus 6 digit addressing is not supported when using modbus format in the driver. Resolution The six-digit address format and the five-digit format are just two different notations for the same thing - there is no difference in the protocol. For example, the first one thousand holding registers are normally represented as: (modbus) 40001 to 49999 -or- (decimal) 0 to 9998 -or- (hex) 0 to 270E When using modbus format in the driver, the left most digit, '4' in this example, is part of a convention that indicates the 'type' of point and, when using that convention, the point type does not have to be specified.  For example, for modbus point 40001 the '4' indicates that it is a holding register. But there are actually 64000 holding registers available and, using the common 5-digit modbus notation, it is not possible to specify more than 9999 of them. The six digit convention just moves this 'type' digit one space to the left. In this six-digit notation, the first one thousand holding registers would be 400001 to 409999. This 6-digit convention for 'modbus' formatted addressing is not supported but it is still possible to use decimal or hex notation to specify these addresses with Niagara R2. When 'modbus' formatted addresses are used, the driver subtracts 1 from the entered address, since modbus uses base 1 formatting and decimal uses base 0.  When using decimal or hex, the leading digit is dropped and subtract one from the register value and optionally convert to hex and use that as the point address. For example, to read data from register address = 422202 Drop the leading character = 22202 Subtract 1 = Decimal address 22201 or hex address 56B9

Issue When viewing the "Device Properties" of an MNB device in the Workplace Commissioning Tool (WPCT) the controller status indicates "Operational, Read-Only"? Product Line TAC IA Series Environment BACnet MNB controllers WorkPlace Commissioning Tool all versions Cause The MNB-xxxx series controllers contain circuitry that is designed to protect the integrity of the embedded flash memory under low-voltage or questionable input voltage conditions.  In the event of a controller-perceived low-voltage condition, the controller will set a read-only flag and lock out all writes to memory, as well as turn off controller outputs. Resolution The Read-Only status can help serve as an indicator that the input voltage to the controller may be questionable. Attention should also be paid to the wire distance between the central transformer and the secondary loads, especially in the case of half-wave input devices like the MNB-70, MNB-V series and MNB-300 controllers and the MNB-1000-15 remote I/O module. With half-wave type input devices, significant AC input current spikes can occur during the positive half-cycle of the AC input. Large resistances due to the wire lengths can cause significant voltage drops as seen from the controller AC input. In extreme cases, the controller may enter the read-only mode at apparent AC voltages exceeding 20 Vac due to the asymmetrical nature of the AC input voltage waveforms. In these cases, reducing the load on the transformer, reducing the wire length between the controller and the transformer, and using higher current rated wire will correct the problem.  For complete wiring guidelines consult the Micronet BACnet, Wiring, Networking, and Best Practices Guide. Once the power issue is resolved cycling power to the controller will clear the read-only portion of the status.

Issue Procedures and processes to secure I/A Series Niagara 4 Systems Product Line TAC IA Series Environment  I/A Series Niagara 4 Systems Cause Users accessing system without permission Potential damage done by malicious entry to the system Resolution The attached document describes how to implement security best practices in an I/A Series Niagara 4 system.  While it is impossible to make any system completely impenetrable, there are many ways to build up a system that is more resistant to attacks. In particular, this document describes how you can help make an I/A Series Niagara 4 system more secure by carefully configuring and using: Passwords System Passphrase Platform Account Management Station Account Management Role and Permission Management Authentication TLS and Certificate Management Module Installation Additional Settings External Factors Please note that while all of these steps should be taken to protect your I/A Series Niagara 4 system, they do not constitute a magic formula. Many factors affecting security and vulnerabilities in one area can affect security in another; it doesn’t mean much to configure a system expertly if your JACE is left physically unsecured where anyone can access it. Note: Schneider Electric strongly recommends upgrading to the latest I/A Series N4 version maintenance build that implements numerous security updates.  Before updating any system, make sure to review the build-included documentation to understand the behavioral impacts of the security enhancements and JACE hardware platforms supported.

Issue Using a VPN with I/A Series Niagara Systems Product Line TAC IA Series Environment I/A Series Systems Cause A VPN's purpose is to provide a secure and reliable private connection between computer networks over an existing public network, typically the Internet. Resolution What is a VPN? "Virtual Private Network" or VPN is a mechanism to extend a private network across a public network such as the Internet. A VPN creates a point-to-point connection or "tunnel" across the Internet between two computers. The tunnel encrypts the data between VPN endpoints, preventing data from being deciphered without the required encryption keys. Why use a VPN? VPN provides an additional layer of security to your Niagara system without compromising your ability to access Niagara. A VPN can help protect your Niagara system from Internet-based attacks by requiring an additional layer of authentication to access Niagara resources. It can prevent automated Internet port scan tools from detecting the Niagara system. How can I set up a VPN? The following document describes how to use an Internet Security Gateway to provide VPN access to your ENC/JACE.  Click on the link to download Using a VPN with Niagara Systems for more details. In addition, the document describes setting up a VPN using a ZyWALL gateway.  The ZyWALL USG-20 unified security gateway (from ZyXEL) is a cost-effective device that you can add to an existing installation to provide VPN server capability. IMPORTANT NOTE: The information in this document is based on the assumption that the only IP devices on the network are Niagara devices. If Niagara devices share a network with other devices (such as a corporate LAN), DO NOT follow the approach described in the following pages. Instead, work with the customer’s IT department to determine the best method to protect both the Niagara and corporate systems while providing required access to the Niagara systems. In any scenario, if the VPN is installed or configured improperly, you can expose devices to the public Internet. If you are unsure about how to best configure and test your configuration, please consult an IT expert. Frequently Asked Questions I already use SSL, do I still need to use a VPN? The use of a VPN is still recommended as an additional layer of security. Attacks can come from both inside and outside of your network. Once I set up a VPN, do I still need to use SSL? Yes. The VPN only provides encryption between the VPN endpoints – the VPN client and server. Traffic from the VPN endpoint to and from the Niagara Station is not encrypted unless SSL is used. I’m running AX 3.6 or earlier without SSL support – should I still install a VPN? Yes. The VPN still helps protect against Internet-based attacks on your system. Do I still need a firewall? Yes. You should set up firewall rules to restrict Internet access to the VPN server port only. You should also consider setting up rules with the VPN server to restrict VPN access to only the required IP addresses and ports. For example, there may be non-Niagara devices on the LAN, but the VPN should be configured to only allow access to the Niagara systems. Additionally, you should only allow access to required Niagara services. Will a VPN affect LAN access to ENC/JACEs? No. LAN access to the Niagara devices remains the same as always. VPN only affects the ability to reach Niagara devices from external networks such as the Internet. If I use a VPN, will Niagara HTTP, Fox, and Platform tunneling work? Tunneling works normally over a VPN. You will need to update IP address assignments. What is the impact of VPN on Niagara Networking? Niagara Networking between systems on the LAN still functions the same whether or not there is a VPN installed. When I connect to a VPN, do I lose all other network connectivity? While your VPN client is connected to the remote VPN network, your Workbench (client) PC will have a new "Default Gateway" to allow you to make connections to stations on the VPN network. Typically, this happens without your knowledge and is mostly transparent. The change is undone after disconnecting from the VPN, and re-done when you reconnect. However (while you are connected to the VPN network) if your Workbench (client) PC tries to connect to sites on the [public] Internet or any other network through any router, you will find that you cannot reach those sites. If you must be able to reach those sites while connected to the VPN network, you will need to add static routes (temporary or permanent) to your Workbench PC’s TCP/IP configuration. The setting of those routes is beyond the scope of this document because they are specific to your PC’s network, your VPN network, and any other networks you try to reach. It is possible (but unlikely) that you cannot resolve these routing issues. This may happen if one or more of these networks have overlapping addresses. Consult with a TCP/IP expert if necessary. Likewise, if you use L2TP, PPOE, PPTP, or PPP for any part of your underlying network connection, the VPN client will probably conflict with it. Specifically, Windows only allows one connection of these four protocol types to be active at any given time. What is the impact on Single Sign On? You will need to define the SSO Domain and the hosts of the SSO Domain in your Workbench PC’s "hosts" file or default DNS server. The DNS server of the VPN will not be able to provide name services without changing your Workbench PC’s TCP/IP configuration. I use Dynamic DNS, can I still use a dynamic DNS provider with VPN? Yes. You will need to register the IP address of the VPN gateway and firewall with the DDNS provider. What is the impact of VPN on my system performance? Impact on performance should be minimal. It does take a little longer to set up the connection. References: Microsoft TechNet VPN Overview 

Issue MNB-1000 BACnet MS/TP communications do not auto-baud (synchronize). Product Line TAC IA Series Environment I/A Series MNB-1000 Firmware 1.2 and above Cause I/A Series MNB controllers with firmware 1.2 and above support baud rate synchronization (auto-baud) for BACnet MS/TP communications. This auto-baud feature is available if the device is configured for BACnet MS/TP communications only.  If the MNB-1000 BACnet Ethernet (or BACnet IP) communications are enabled, even though this is not being used in normal operation, it will cause the auto-baud to be disabled. Resolution 1. Disable the BACnet Ethernet (or BACnet IP) communications on the MNB-1000. Use a compatible RS-232 to RS-485 converter or the Roam IA to access the MNB-1000 via BACnet MS/TP communications. 2. Set the baud rate of the MNB-1000 MS/TP port to a fixed speed that matches the configured baud rate of the RS-485 port of the Jace. - Connect to the MNB-1000 using the WorkPlace Commissioning Tool. - Go to the MNB-1000 device properties, MS/TP tab, and set the baud rate of the MNB-1000 MS/TP port. See the example below.

Issue A correct IP, Subnet Mask, and Default Gateway addresses are required for the MNB-1000 to communicate properly via BACnet/IP but what about BACnet Ethernet? BACnet IP requires a valid IP address to be routed in a TCP/IP network. please read the example below in the resolution BACnet Ethernet requires a valid six-byte MAC address assigned by the manufacturer and only operates within layer 2 of the OSI model.  It is non-routable protocol Example of Ethernet address:  00:00:AC:56:78:90 Product Line TAC IA Series Environment I/A Series MNB 1000 Cause BACnet IP is a requirement and needs information on configuring the settings to enable communications. Resolution MNB-1000 controllers must have a valid IP address, Subnet Mask address, and Default Gateway address for the communication ports to function properly if BACnet/IP is enabled. If 0.0.0.0 is used, the communications ports may be disabled and no longer communicate after the controller is reset. In the event that 0.0.0.0 was entered and the communications port is disabled, there is currently no field workaround or way to repair it. The controllers will have to be returned to the factory for repair. Never enter an invalid IP, Subnet Mask, and Default Gateway address for new installations. Review and update current installations. To connect to the MNB-1000 for the first time it will require an Ethernet connection.  When you select the BACnet IP tab and enable IP the default IP address from the factory is a valid address of 10.1.10.2 with a subnet mask of 255.255.255.0. Default example: IP address 10.1.10.2 Subnet mask 255.255.255.0 Gateway 0.0.0.0  (If you do not have a default gateway IP address then enter 0.0.0.0 in the default gateway section)

Issue BACnet/IP controllers are not configured in RSTP Mode by default, therefore must be configured during installation. Having RSTP Mode disabled by default allows one to connect BACnet/IP controllers to any switch, even with port security configured to detect BPDU packets and disable the port. Product Line EcoStruxure Building Operation, TAC IA Series Environment Multi-purpose Controller (MP-C) Multi-purpose VAV (MP-V) Room Controller IP-IO I/A Series N4 Jace8000 SmartX IP Driver for Niagara Cause RSTP protocol requires that controllers, switches, and network architecture are configured to ensure the protocol will operate as expected.  Resolution Setting RSTP Mode for BACnet/IP Controllers ALL devices in the RSTP loop MUST BE IN RSTP MODE to function properly. This is not a huge issue because during startup you can unplug 2nd side of the loop and it will function properly in a daisy chain. Ensure the SmartX Controllers are configured correctly Configuring BACnet/IP Controller Device Settings A factory or network reset returns the RSTP setting to Disabled. Important: Whenever you make changes to RSTP the controller MUST be restarted. If you fail to perform this restart, the BACnet/IP controller will continue communicating using its previous RSTP settings. 'Activate IP Changes' does not affect RSTP mode. Ensure the switch is configured properly per Configuring RSTP on a Managed Switch for SmartX IP Controllers Bridge Priority = 4096 Hello Time = 2 sec Max Age = 40  (40 is the maximum value allowed by the protocol. Default is 20) Forward Delay = 21 sec Change Bridge Priority by adding 4096 as switches get further away from AS. (8192, 12288, 16384, 20480, 24576, 28672) DO NOT set the priority as 32768 or higher because that is the built-in Bridge Priority of BACnet/IP Controllers. Configure the Root Bridge Switch (closest to Automation Server) settings first Then configure the additional Switches in order of increasing Bridge Priority. Plug in 2nd side of the RSTP Loop If all devices stay online, then it is working properly. Now test line breaks or controllers that are powered off. If all devices go offline and/or the switch LED is flashing rapidly, then go to RSTP Troubleshooting. Managed Switch Troubleshooting Ensure the switch is IEEE 802.1D - 2004 capable. BACnet/IP Controller Networking Term Definitions RSTP Ring mentions the Rapid Spanning Tree Protocol is specified in IEEE 802.1D - 2004. Ensure the firmware is up-to-date by contacting the vendor or manufacturer or downloading it from its website. Ensure ports not participating in RSTP are configured as Edge Port, Admin port, or have STP disabled. Nomenclature for those settings on your specific managed switch may vary so consult the documentation or contact the vendor or manufacturer to assist with configuration. Adding BACnet/IP controllers to site-managed switches, work with Local IT to add these devices to their network. They will need to work with their switch vendor/manufacturer/support group to ensure the configuration of those switches because it could be more complex than changing the minimum recommended four settings above.
