Channel Configuration
Protocol Options
- BlockSize: Determines the maximum block size. Default is 29 Word Addresses
- Ignore Non Critical Error: Indicates the driver behavior when the PLC returns the 64 status that is a non fatal error:
- True: If it returns a Success with the 64 error code, set the tag quality to GOOD
- False: If it returns a Failed with the 64 error code, set the tag quality to BAD
- Change the PC mode for Writings: Indicates whether the communication driver should send a command that changes the PLC state to MONITOR in order to perform writing operations, otherwise the writing will fail (error code 1). Default is True
Settings - Serial channels:
Default RS-232 serial port configuration.
Node Configuration
Station Configuration - Serial (RS232) Channels
Syntax: <Unit Number>
Where:
- <Unit Number> is the PLC address
Station Configuration - Multi Serial channels:
Syntax: <ComPort>; <Unit Number>
Where :
- <Port>: COM port for communication (default is com1)
- <Unit Number> is the PLC address
E.g.: com1; 0
Points Configuration
The syntax for the communication points is: <Memory Area> : <Address>
The Valid Memory areas are:
