The WITS0Pason communication driver implements communication with servers running WITS Level 0 communication. 

Summary Information

Communication Driver Name: WITS0Pason

Implementation DLL: T.ProtocolDriver. WITS0Pason.dll

Protocol: WITS Level 0 Pason

Interface: TCP/IP, UDP, or RS232

PLC types supported: WITS servers outputting Level 0 data streams

Multi-threading: User defined

Max number of nodes: User defined

PC Hardware requirements: Standard PC Ethernet interface board

Supported Operands: Any tag defined on the target system


Channel Configuration

Settings

None


Node Configuration

The address is necessary, as this driver works in listening mode only. When connecting to multiple devices, multiple channels shall be defined


Point Configuration

Address

The syntax for the communication point is: RecordID:ItemID

Where:

  • RecordID = ranges from 01 to 99, according to the WITS Level 0 record definition
  • ItemID = ranges from 01 to 99, according to the WITS Level 0 record definition


Troubleshoot

The status of the driver's execution can be observed through the diagnostic tools, which are:

• Trace window
• Property Watch
• Module Information

The above tools indicate if the operations have succeeded or have failed. A status of 0 (zero) means communication is successful. Negative values indicate internal driver errors, and positive values indicate protocol error codes.
