How To Change The IP Add ress Of The CP1W -CIF41 Ethernet Option
Board With CX-Programm er?
It is not possible to change the IP address of an out-of-box
CP1W-CIF41 with USB/Serial PLC
connection method without first connecting to the unit via the
Ethernet/web browser. You must
change the default IP address from 192.168.250.1 to 0.0.0.0
using the web browser function. After
this initial change is made we can use CX-Programmer connected
via USB/Serial to alter DM
values in n+155 and n+156 changing the IP address
accordingly.
If the IP address in the web browser is not 0.0.0.0, the IP
address display/setting area n+155 and
n+156 will act as a display area only. In this condition the PLC
memory values will be overwritten
upon power up or restart. Changing this PLC memory area value
will have no effect on the unit IP
address.
If the IP address in the web browser is 0.0.0.0, the IP address
display/setting area n+ 155 and n+156 will act as a
setting area. In this condition the CP1W-CIF41 uses this PLC
memory area as the IP address for configuration on
power up.
Note: Changing IP address with DM memory locations may cause
errors on the CP1W-CIF41. Address
disagreement error may occur when the FINS node number set for
the option board does not agree with the host
ID in the IP address. This probably occurs when the address
conversion method is set for automatic address
generation. To prevent this error change address conversion mode
to manual with the web browser.
Additional info: DM memory location varies per controller type
and option port number 1-2. The following
information describes the unit address for each option port.
Option Port No I / O Capacity Unit Address Range of Status
Area
Option port 1 14/20 0xFC DM32300 to DM32456
30/40/60 0xFD DM32000 to DM32156
Option port 2 30/40/60 0xFC DM32300 to DM32456
n = DM32000 + 300(0xFD - Unit Address)
n = Mode setting (2 bytes)
n+1 = FINS/TCP port number (2 bytes)n+2 = FINS/UDP port number
(2 bytes)
n+3 = IP address (4 bytes)
n+5 = Subnet mask (4 bytes)
n+7 = Reserved (2 bytes)
n+8 = IP address table (194 bytes)
n+105 = IP router table (66 bytes)
n+138 = FINS/TCP connection setup (22 bytes)
n+149 = HTTP server setup (10 bytes)
n+154 = FINS node address (2 bytes)
n+155 = Using IP Address Display/Setting Area (4 bytes)
An example configuration is shown below.
Default web address: http://192.168.250.1/E00.htm (E00 for
English, J00 for Japanese, C00 for Chinese)
