2.3.3 PGM mode (500)
The last known IP address, subnet mask and gateway address are saved in the EEPROM when rotary
switches are set to 500. The IP address is programmable and may be programmed using TURCK Service
Tool or Web server. The procedure:

Assign an IP address using either static rotary mode, or BOOTP/DHCP server

When IP address is acquired, change rotary switches position to 500

Cycle the power of the device
2.3.4 PGM-DHCP mode (600)
When out-of-box device is powered for the first time, while switches are set to 600, the device DHCP
client is active and waiting for an IP address assignment. Use any DHCP server to assign the IP address.
When IP address is acquired, the device disables its DHCP. The device saves permanently assigned IP
address and transitions to the PGM mode.
2.3.5 Factory Reset mode (900)
The factory reset mode resets the device back to the factory default setup and deletes all custom data in
the device’s internal flash. The procedure:

Set address switches to 900

Power-up device and wait 10sec

Set switches to either static rotary mode or 300/400/500/600

Cycle power
2.3.6 Restore IP Address (000)
Set rotary switches to 000 to restore IP address to 192.168.0.254. The device preserves custom
data/setup while restoring IP address.
From any switch position:

Set the address switches to the position 000

Power-up device and wait 10sec

Set switches to either static rotary mode or 300/400/500/600

Cycle power

Depending on the position of the rotary switches, the device comes up as previously described.
