This section includes examples of ClearSCADA configuration that might be used to allow the ClearSCADA Simple Modbus driver to transmit data to and from Modbus PLCs.
The examples refer to Modbus Register range addressing—for more information on Modbus address ranges, and a sample table of such addressing, see Modbus Register Ranges.
The Modbus address with which a channel, scanner, or point is associated is displayed as part of the Source status attribute. The Source attribute is displayed on the associated List and Status display for each item (see Modbus Specific Status Display Attributes).
Use the examples as an aid when configuring your ClearSCADA system. The examples in this section include:
- A Modbus Scanner Configured to Scan Four Input Registers
- A Modbus Analog Input Configured to Present Data in UINT Format
- A Modbus Analog Input Configured to Present Data in DINT Format
- A Modbus Digital Input Configured to Contain Input Register Data
- A Modbus Scanner Configured to Scan a Block of Output Coils
- A Modbus Digital Input Configured to Contain Output Coil Data
- Sample System Requirement and Solution
- Use Modbus RTU to Communicate via a Terminal Server.
