Appendix C: Graco Gateway to ControlLogix via Ethernet IP
The following settings mirror the I/O settings of the ControlLogix configuration detailed earlier.
a.Input Connection Point. Create a Gateway block configuration (see Table 7).
Table 7: Input Connection Points
Connection Point | 2 |
|
|
Data Offset | 0000 |
|
|
Data Type | Long as Long |
|
|
Block Size | 2 |
|
|
Direction | Graco Gateway to Device |
|
|
b.Output Connection Point. Create a Gateway block configuration (see Table 8).
Table 8: Output Connection Points
Connection Point | 3 |
|
|
Data Offset | 0000 |
|
|
Data Type | Long as Long |
|
|
Block Size | 2 |
|
|
Direction | Device to Graco Gateway |
|
|
4.Data Mapping. the connection points are now con- figured so that:
Gateway_HMI:O >> PLC1:Block1 Gateway_HMI:I << PLC1:Block2
5.Testing. Using the RSLogix5000 program, you can modify tags Gateway_HMI:O and verify they are written into Var1 and Var2, and verify changes made in the Gateway to tags Var3 and Var4 are updated in Gateway_HMI:I. Ensure the device is in the Run mode, otherwise the data transfer will be ignored by the Gateway.
