ETHERNET INTERFACE
ETHERNET port, used for controller monitoring, can realize network client connection.
NOTE:
After changing controller network parameters (e.g. IP address, sub network mask etc.) new settings will take
effect only after the controller is restarted.
15.1
NETWORK CLIENT CONNECTION
When the controller is used as network client
，
it can be monitored via network port by using TCP
ModBus protocol.
The procedure is as below:
— Set IP address and sub network of the controller. The IP address must be in the same network
segment as the IP address of monitoring equipment (e.g. PC), but different from each other. e.g.: if
monitoring equipment IP address is 192.168.0.16, controller IP can be 192.168.0.18, sub network
mask 255.255.255.0.
— Connect the controller. It can be connected to the monitoring equipment directly by using network
cable or via switchboard.
— The communication between the controller and monitoring equipment is carried out by using TCP
ModBus protocol.
NOTE:
In this connection mode controller parameters can be set. SmartGen provides testing software for this
connection mode. Communication protocol can be obtained from the SmartGen service.

— Controller connects with PC with a piece of cable line directly.
For this connection crossover cable must be used.
Crossover cable: EIA/TIA 568A standard on one end and EIA/TIA 568B on the other end.
NOTE:
If PC network port has Auto MDI/MDIX function, parallel cable can also be used.
— Controller and PC connection is done via switchboard (or router).
Parallel lines must be used.
Parallel cable: EIA/TIA 568A standard on both ends or EIA/TIA 568B standard on both ends.
NOTE:
If switchboard (or router) network port has Auto MDI/MDIX function, crossover cable can also be used.
