Allen Bradley Micrologix 1000 and Intouch SCADA communication
To set up communication between a MicroLogix 1000 PLC and *Wonderware InTouch SCADA*, follow these steps:
---
1. Communication Driver
MicroLogix 1000 uses DF1 protocol or *RS-232*. You’ll need a communication driver that supports it:
Use KEPServerEX or RSLinx Classic (OEM or Gateway) as the OPC server.
Set up RSLinx as an OPC server if you’re not using KEPServer.
---
2. RSLinx Configuration
Open *RSLinx*.
Add a new RS-232 DF1 driver (configure COM port settings).
Confirm PLC is visible under *RSWho*.
---
3. InTouch SCADA Setup
Open *Wonderware InTouch*.
Use WWOPCLink or SuiteLink to connect to the OPC server.
Define your *Access Name*:
*Application Name*: `RSLinx OPC Server`
*Topic Name*: As set in RSLinx (e.g., `ML1000`)
*Protocol*: OPCLink

4. Tag Configuration
Create a tag in InTouch:
Type: Memory/Discrete/Analog (depending)
Access Name: The one you set
Item: Tag address in the PLC (e.g., `N7:0`, `B3:1/0`)
---
5. Test Communication
Run InTouch app and observe data updates.
Use diagnostics in RSLinx or KEPServer to troubleshoot.
