5.9.2.2.2 ABLogix : EIP Ethernet link
The Global Device Address has the following syntax : IP Address,Port,Link
• IP Address = address on your Ethernet network (i.e.: 10.0.30.7)
• Port = value from 1 to 3 representing: 1 = Backplane, 2 = Channel A, 3 = Channel B
•
Link could be:
¤ Slot: representing the Slot on the Backplane (for example: 0=CPU)
¤ Node ID: value from 0 to 99 (for ControlNet)
¤ IP address
Figure 89: ABLogix : EIP address example
REM: In the case of using a ControlLogix as Gateway, the Device Address could be like following: IP Address, Port, Link[,
Port,Link][, Port,Link]…
5.9.2.2.3 DH+ polling using ControlLogix gateway
This feature allows the eWON to poll PLC tags located on a DH+ network, behind a controllogix equipped with one or more DHRIO cards.
Polling is done using the eWON EIP protocol.
The ABLOGIX IO server is used to access the “LOGIX” PLC family.
The DF1 IO server is used to access the “SLC500” PLC family (See “DH+ polling using ControlLogix gateway” on page 102).
The general syntax IP address,Port,Link is still applicable. There is no specific character to indicate the DH+ channel (“2” or “3” should be used).
Example: To reach a PLC5 (with CPU in slot 0) with DH+ node Id 3 using channel A of a DHRIO card at slot 9 of a controllogix at IP address
10.0.30.21.
Topic A Destination = SLC500-10.0.30.21,1,9,2,3,1,0
• 10.0.30.21 = IP address of the ControlLogix
•
1 = BackPlane
•
9 = Slot 9 (COM card)
•
2 = Channel A (of the Card present in Slot 9)
•
3 = NodeID of the PLC5 (in the COM network)
• 1 = BackPlane
• 0 = slot (of the CPU in our example)
5.9.3 Tag name convention
The Item Name can contain the PLC address where the value is polled, or not. If the address is also specified at topic level, the address specified
at Tag level will be ignored.

IO server Name ABLOGIX
Topic name A or B or C
Item Name ValueName Topic PLC address is used
ValueName, IP address[, Port, Link] PLC address is defined Tag by Tag
