AccuWeb MICRO 4000 NET, Instruction Manual

Page: 135 / 155

Ethernet TCP/IP and Modbus/TCP Addressing:
The read command (MICRO 4000 NET to Fieldbus Master (host)) must use register 40001.
The write command (Fieldbus Master (host) to MICRO 4000 NET) must use register 41025.
Setting the IP address:
If the module’s DIP switch setting is set between 1 and 255 the default settings below will be
used:
IP address: 192.168.0.X
Subnet mask: 255.255.255.0
Gateway address: 0.0.0.0
The last byte (X) in the IP address is set to the module’s DIP switch setting. Switch 1 is the MSB,
and switch 8 is the LSB. When a switch is in the “On” or “Closed” position, it is interpreted as a
“1”.
If the DIP switch setting is 0, then the IP address that is stored in the FLASH memory will be
used.
If no settings are stored in the FLASH memory, then the module will not accept the END
INITIALIZE process and the Status LED will flash Red at a 2Hz rate to indicate that the attempt to
load from FLASH failed.
The settings can be stored in FLASH memory through a web page located in the module. To
access this web page, set the IP address of your computer to the IP address above, use 254 for
the last byte (X). Set the module’s DIP switch to 1 (00000001). Using Internet Explorer, browse
for the IP address above; use the module’s DIP switch setting for the last byte (X). A web page
will appear with information on changing the IP address of the card. After changing the IP
address of the card, set the DIP switches to 0 and cycle power to the MICRO 4000 NET. The
card’s FLASH memory will now load the new IP address from FLASH memory.
