Configuration and operation of the device is detailed below. Product Overview EGW1-MB-HT module is a device used to connect any instrument with HART communication to one or more Modbus Masters, Modbus TCP or Modbus Serial (RTU / ASCII).
N° 1 and negative power supply to terminal No. 2 as shown in the following figure: Serial Port Wirings EGW1-MB-HT has two serial ports; one of them is RS232 (Port A), used as a Modbus slave and as a configuration port through the serial (Appendix A), and other one RS485 (Port B) used as Modbus Slave.
2.3. HART Ports EGW1-MB-HT three HART ports: HTa, HTb and HTc. All three ports share the HGND terminal to close the loop. One or more HART instruments can be connected to each port. To connect two or more instruments, they must be configured in MULTIDROP mode and denote a different HART address to each one.

2.4. LEDS Indicators EGW1-MB-HT has three LEDs, two of them on the Ethernet connector, the yellow one shows the connection to the network, while the green one indicates the status of the Modbus TCP connection. The Power LED indicates device is on.
The rest of the configuration is done from the configuration web page of the device. In case you do not have a DHCP server, the Exemys Device Locator will find the device with IP address 0.0.0.0, as shown in the figure below.
Configuration web page Once the EGW1-MB-HT has a valid IP address, you can access the web page to configure the other parameters (If your web browser is configured to search for a proxy server, disable this option) Type the EGW1-MB-HT IP address in the address field of your browser or from the Exemys Device Locator, press the Configure button.
Modbus Configuration has an internal Modbus slave containing the values of all HART devices configured. EGW1-MB-HT This slave can be accessed by multiple means of communication: Ethernet (Modbus TCP), RS232 and RS485 (Modbus RTU or ASCII) Modbus TCP The only possible configuration is to define the connection port of the Modbus TCP slave. The TCP...
Another characteristic is to define the behavior in case of failure, if the connected device has a malfunction, we can determine in the values of the Modbus map a behavior that is defined in 3 options: Keep the last value read, show NaN or a predefined value that is useful. HART Configuration Basic Configuration We can define the number of retries on the HART ports.
Password The web page and the configuration by Exemys Device Locator can be protected with a password. This password can also be set from the Exemys Console (see Appendix A). It only admits alphanumeric characters. The user to enter when asked is "admin".
MODBUS REGISTERS The values read from HART devices are available in HOLDING REGISTER and INPUT REGISTER area. For each HART device, 20 registers are reserved. Registers of the HART PORT A first device Holding Input Value Format Register Register 0: fail or disabler disabled 40001 30001 Estado...

MONITORING, MANUAL SENDING, HART OVER TCP Data Monitoring EGW1-MB-HT allows to monitor the communication between the device and the HART transmitters connected to its ports. For this you must set a TCP connection to port 999 with some TCP client terminal software (for...
0000 00FB 62 AD Transparent Mode (HART over TCP) This function allows the EGW1-MB-HT to be used as a HART converter over TCP to HART. This allows the configuration software of each transmitter to be used remotely, arriving at the location through a TCP connection.
Select with double click the port where device is connected. Verify Baud rate in the serial por is 9600. 2. Turn on the EGW1-MB-HT and in the first 7 seconds type CFG and press ENTER or press the CFG button. EGW1-MB-HT will display a welcome message on the configuration command console.

3. Type the configuration command according to the following table. Command Description NETWORK: Change the basic parameters of the network Ip, netmask, Example: NETWORK:192.168.0.212,255.255.255.0,192.168.0.200 gateway Change the configuration password. PASSWORD: password Password must have a maximum of 10 characters or empty to delete it. LIST Request the current device configuration.
B. IP ADDRESS USING ARP PROTOCOL If for some reason you cannot set an IP address using the Exemys Device Locator, you can use the method described below. This method is complex and is only recommended as an alternative method.

3. On command prompt, request a PING to the device IP address (The -t option will cause the command to be sent continuously) ping 192.168.0.213 -t 4. Wait for a few seconds until the PINGs start responding Once the IP address has been set, enter the Configuration web page to set the other parameters. Rev.

D. DIN RAIL MOUNTING Device can be mounted on a DIN rail. To assembly the module to the rail, make the upper side of the device fit the DIN rail and then push gently until you hear a Click! As shown in the figure. To disassemble the device of the rail DIN, pull down the metallic clip and then remove it as shown in the figure.
(V1.0.52) and the serial port redirector software SerialIP. Steps 1) Install the SerialIP redirector, add a COM port and configure the EGW1-MB-HT IP address the TCP port (10001, 10002 o 10003 for ports A,B or C) in Raw TCP Connection mode 2) Install the CodeWrights HART Communication FDT 1.2 DTM (V1.0.52)
Page 27
4) Add a new port using the new DTM and open the Paramenter tab 5) Select the COM port previously added in SerialIP. In the Address scan section change the Start and End address in case you have multiple devices with different addresses connected to the EGW1-MB-HT port. Rev. 3...
