Configuration file

  • The CPU is in slot 1 and the EtherNET/IP coupler is in slot 2.
  • The cable on the coupler is plugged into the physical port 1.
  • The IP address of the EtherNet/IP coupler is 192.168.0.31.
  • The IP address of the PcVue host PC is 192.168.0.10.

This requires the following settings in the EthernetIP.ini configuration file:

Copy 
[TaskParameters]
AttributeNumber = 4
LocalIpAddress = 192.168.0.10
nbEquipments = 1
nbPollingGroups = 1

[PollingGroup1]
Name = Fast
RefreshRateInSec = 1

[Equipment1]
Name = EqtTest
IpAddress1 = 192.168.0.31
Port1 = 1
Slot1 = 1
TimeOutInSec = 2

Variable definition

To access the variable ANA_IN_00, which is UINT format, you must use a register variable. The variable is configured with the following string in its extended attribute 4 (as specified in the .ini file AttributeNumber = 4). ClosedShow picture
