ADC Gateway Help Page


Device Information

 The Device Information page displays a summary of information to identify the gateway.

 The device name is configured on the Network Settings page. The device name helps users distinguish between multiple gateways.

 The serial number (“SN”), model type and MAC address(es) are not configurable. These are characteristics of the individual gateway and may help distinguish between multiple gateways. The values that display on this page may be compared to the values printed on the device label.

 The IP address(es) are configured on the Network Settings page. IP addresses must be unique on the network.


Network Settings

 The Network Settings page allows selection between DHCP and static network settings for the Ethernet port(s).

 IP addresses must be unique on the network.

 On models with two Ethernet ports, the two ports may be configured on the same subnet.

 A Default Gateway must be configured if any devices will be configured as Modbus TCP servers on a subnet different than the STRIDE gateway Ethernet port.

 The device name helps users distinguish between multiple gateways. It may have a maximum 16 alphanumeric characters, or special characters dash ( - ) or underline ( _ ).


Operating Settings

 The Operating Settings page is where each serial interface’s operation mode is configured.

 The Operating Mode describes the function of each serial port on the Gateway.

 If the serial port will function as an ASCII or Modbus Master, the Slave ID and IP address of each server device on the Ethernet ports must be configured. Additionally, each server device must be assigned a local and remote TCP/UDP port. The Ethernet protocol, TCP or UDP, must be configured, and the Ethernet port through which each server device is reached must be identified (Ethernet Port Bind). A Default Gateway must be configured on the Network Settings page if any devices will be configured as Modbus TCP servers on a subnet different than the STRIDE gateway Ethernet port.

 For SGW-MB1524-T which has two Ethernet ports, when a serial master will connect to one or more Ethernet servers that are on subnets different from the Subnet that the Gateway Ethernet ports are on, the devices in each row of the serial settings table must be bound to an Ethernet port AND a default gateway must be configured on the network settings page.

 If the up addresses of the Modbus Devices are on the same subnet as the gateway up address then the Ethernet device does not need to be bound to an Ethernet port.

 In Slave mode, the filter option will eliminate port numbers from the processed traffic when enabled. To enable the filter feature, check the Filter enable box and enter the starting number and ending number of the nodes that should never appear in messages that will be processed.


Serial Settings

 The Serial Settings page includes the configuration settings that must match the settings on the connected serial devices..

 Alias name helps users distinguish between the serial networks connected on each serial port. This name appears on the Message List page.

 Databits is determined by the serial interface operation mode that is configured on the Operating Settings page. Note that the setting on the connected devices must match this value.

 Baudrate, Stopbits, Parity and Flow control settings must all match the settings on the connected serial devices.

 The Hardware Interface selection must match the wiring on the serial network. Refer to the manual for wiring details.


Agent Settings

Gateway Settings

 The Gateway Settings page is available under Agent Settings when the gateway is configured for Agent mode, as selected on the Device Information page.

 The Gateway Modbus ID must be unique on the serial network. This is the ID that Modbus client devices will use to request data from the gateway’s local cache. The data in the gateway’s local cache is configured on the Message List page.

 The protocol, Gateway Modbus port (on the Ethernet network), and Interpacket delay are configured to match the requirements of the connected Modbus TCP devices. Refer to the documentation provided by the manufacturers of those devices for these details. Port 502 is the well-known port for Modbus TCP communications.

 Default Timeout may be increased to increase success on busy networks.


Message List

 The Message List page is available under Agent Settings when the gateway is configured for Agent mode, as selected on the Device Information page.

 The Message List page displays a table that summarizes the data stored locally in the gateway’s memory. Modbus client devices may request this data from the gateway’s local cache.

 When the gateway is in Agent mode, addresses that devices will use to WRITE data into must be configured in the Message List even though conceptually this is a list of data that is READ from connected devices.

 Click the Add Message button to call the new message dialog. Enter the following values for each data block that will be read from a connected device:

 Slave alias: name for each device to help users recognize it more easily

  •Serial port: the gateway serial port number to which the device is attached.

  •Slave ID: the device’s Modbus node ID on the communication network.

  •Function: the Modbus protocol function code. Function codes are listed in the table below.

  •Starting address: the address in the target device from which the gateway will read the data.

  •Data length: the data block size the gateway will read

  •Mapping address: the location in the gateway’s shared memory (cached data) from which the data will be retrieved when a Modbus TCP query is received. Ensure that this memory block does not overwrite a block configured for another message.

 The Assign Next Available Address checkbox is a convenience to prevent data blocks from overwriting other blocks. When selected, the gateway will automatically assign an internal memory block where this message data will be stored.

 Highlight a message row in the Message List table the click the Modify Message button or the Delete Message button to Modify or Delete it.


Data in Gateway Memory

 The Data in Gateway Memory page is available under Agent Settings when the gateway is in Agent mode, as selected on the Device Information page.

 On the Data in Gateway Memory page, you may query the real-time data stored in the gateway’s local cache as configured on the Message List page.

 Enter the Modbus function code (shown in the table above), the starting address and the length of the data block to display. The Starting Address refers to the gateway internal address (Mapping Address Head) as shown in the table on the Message List page.

 Ensure that all addresses in that block are configured in the table on the Message List page. Querying data outside of those ranges will result in invalid values displaying on this page.


Import/Export

 The gateway configuration settings may all be exported and saved as a convenience when replacing this gateway or configuring multiple gateways with identical or similar settings.

 Saved configuration files may be imported to a gateway.


Upgrade Firmware

 Occasionally firmware revisions are released to make new features available or to fix bugs. To update the firmware, click Browse to locate and select the new firmware file on your PC, then click Upgrade.

 The gateway must be rebooted after firmware is upgrades in order for the new firmware to take effect.


Changed Password

 The Stride gateways allow browser management access for the username “admin”. The default password is admin. To provide an additional level of security, the password may be changed.

 Make sure to record the new password. If the password is lost, the gateway must be reset to factory defaults using the hardware reset button.

 HTTPS may be selected to encrypt the traffic between the browser and the gateway. When HTTPS is selected, the IP address in the browser address bar must be preceded by https:// For example, “https://192.168.0.249”

 When a new password is entered here or HTTPS is selected, the browser will log you out of the current session and return you to the login page to login using the new password.


Load Factory Default

 In addition to the hardware Reset Defaults button on the top of the gateway, default settings may be loaded from the browser interface. Upon clicking the “Load Defaults” button, the gateway will automatically reboot in order for the change to defaults to take effect.

 Note that this will rest the IP address(es), the password and the HTTP access.


System Reboot

 Reboot will restart the gateway.

 Reboot here, or power cycle at the gateways itself, is required after a firmware upgrade to make the new firmware take effect.


Exit

 Exit will log you out of gateway management. Any unsaved changes will be lost.
