Citect can communicate with ThinkNDo
software through the use of OPC. ThinkNDo will act as an OPC server
while Citect can be configured to be the OPC client. The following
shows how to configure the forms in Citect.
I/O Server Form:
Boards Form:
| Board Name: |
OPC_Board |
| Board Type: |
OPC |
| Address: |
15 (This is the scan rate in
milliseconds) |
| I/O Port: |
(N/A - leave
blank)
|
| Interrupt: |
(N/A - leave
blank)
|
| Special Opt: |
(Enter the OPC Server machine
name)
|
Ports Form:
| Port Name: |
OPC_Port |
| Board Name: |
OPC_Board |
I/O Devices Form:
| Name: |
ThinkNDo |
| Number: |
1 |
| Address: |
ThinknDo.TnDOPC |
| Protocol: |
OPC |
| Port Name: |
OPC_Port |
Note: With the OPC client driver from Citect, if you need to
create multiple OPC groups you can do so by creating multiple I/O
Devices in Citect to the same OPC Server. Each OPC I/O Device in
Citect creates an OPC group. |
