INIT Function
The INIT function facilitates access to a device when there is a problem accessing it at its configured IP address. The configured
username and password are required for INIT access.
The INIT terminal is adjacent to the power terminals. Applying power to the device while the INIT terminal is shorted to the -VS
terminal causes the device to request a temporary IP address from the DHCP server on the network. If there is no DHCP server on
the network, the device will temporarily use 192.168.1.174.
The temporary INIT mode Modbus ID is 245.
Once connected in INIT mode, device network parameters (IP address, subnet mask, etc.) may be changed to conform to the
requirements for your industrial network. Other parameters may also be modified while INIT mode is active. Once the short (or
jumper) is removed from the INIT and -VS terminals, the device can be accessed using the user-configured IP address, username, and
password.
NOTE: If not using DHCP, verify that 192.168.1.174 is not in use on your network and ensure that the 192.168.1.n network is
accessible to your computer.
To use the INIT function:
• Before applying power to the device, short the INIT terminal to the -VS terminal.
• Apply power to the device and connect the RJ45 Ethernet port to your computer.
• Open a browser and type 192.168.1.174 or the DHCP-assigned address in the address field.
• Browse through the user interface to view configuration settings and data, or change configuration settings.
• When all changes are complete and saved, disconnect power from the device.
• Remove the connection shorting the INIT and -VS terminals.
• Apply power to the device and access it from a browser using the configured IP address, user name and password.
Hardware Reset to Default
With the device powered and not in INIT mode, push and hold the RESET button located on the front of the device for 5 seconds.
The green PWR LED will switch off, the yellow STS LED will turn orange and the device will reset.
When the reset procedure is finished, both LEDs will be in the default condition and the following parameters will be set:
• IP Address: 192.168.1.100
• Subnet Mask: 255.255.255.0
• Default Gateway: 192.168.1.1
• Modbus Address: 1
• Username: admin
• Password: password
Watchdog Function
The device is equipped with a Watchdog timer. If enabled, it activates an alarm each time that there is not communication between
the device and the master for a time greater than that specified.
In alarm condition, the output values are automatically set to the values specified in the relevant "Safe" registers. During this alarm
condition the green PWR LED on the front of the device blinks and the "Watchdog Event" coil is forced to 1. To exit from the alarm
condition, send any command to the device and reset the "Watchdog Event" coil.
NOTE: When the device is switched off the state of the "Watchdog Enable" bit remains stored in EEPROM.
