PLC side settings
Configure the settings for "MICREX-F F120S" and "NC1L-ET1". The settings are configured using MICREX-F PLC Programmer.
1.Set the front switch of the "NC1L-ENT1" unit as follows:
switch |
NC1L-ET1 |
FFU170B |
Communication condition setting switch |
All OFF |
|
10Base2/T changeover switch |
T side |
- |
AUI/TPI Switch |
- |
TPI side |
10Base2/2 Switch |
- |
Either |
|
Specify the end of the IP address with the switch on the back. There are two switches, H and L, which are hexadecimal switches.
In this setting example, the last digit of the IP address is 100, which becomes "100" → "64" when converted to hexadecimal, so set H to "6" and L to "4". |
|
The end of the IP address is determined by the "IP address setting switch", not the ladder. |
|
The above example is the setting that works with "Ethernet User's Manual Chapter 7 Sample Program." In this connection example, TCP is selected as the protocol. Therefore, TCP must also be selected in the unit's communication settings. |
2.Set the rear switch of the "NC1L-ENT1" unit as follows:
3.Using MICREX-F PLC Programmer, refer to Fuji Electric's "Ethernet User's Manual, Chapter 7 Sample Program" and write the following ladder.
4.Write the ladder
5.Refer to Fuji Electric's "Ethernet User's Manual" and set the initial parameters and communication parameters to the address (tag) of the relevant device as follows.
