Port MODELACCESS - DEFAULT 🛈

Model access

Stimulation

This port has no stimulus capabilities.

Supported execution modes

See also: Temporal behaviour: Real time and simulation time modes

Preferred time source/mode: Real-time

Real-time:

To use real-time mode, the Test configuration in the Execution tab must be configured as the source ‘real time’.

Read-timeout		10.0		float	Timeout for read operations in s Hint: If set to None, read operations do not return until the desired number of Bytes was read. The value ‘0’ makes the job return immediately.
Write-Timeout		None		float	Timeout for write operations in s Hint: If set to None, write operations do not return until the desired number of Bytes was written. The value ‘0’ makes the job return immediately.
Intercharacter-Timeout		‘None’		string	Timeout between individual transfer bytes in s
XON/XOFF		☐		bool	Software flow control
RTS/CTS		☐		bool	Hardware flow control: Hint: If using a RS-232 to RS-485 converter, this option has to be activated.
DSR/DTR		☐		bool	Hardware flow control
