Instruction Description
GSV Amount of time to delay transmitting the first character of a message after turning on the RTS
line. Valid value 0...32,767. Delay in counts of 20 msec periods. The default is 0 msec.
GSV Specifies the number of stop bits.
Value Meaning
1 1 stop bit (default)
2 2 stop bits (ASCII only)
SSV Pending value for the BaudRate attribute.
SSV Pending value for the COMDriverID attribute.
SSV Pending value for the DataBits attribute.
SSV Pending value for the DCDDelay attribute.
SSV Pending value for the Parity attribute.
SSV Pending value for the RTSOffDelay attribute.
SSV Pending value for the RTSSendDelay attribute.
SSV Pending value for the StopBits attribute.

Task Attributes

The Task object provides status information about a task. Specify the task name
to determine which Task object that you want.

Description
Enables or disables the processing of outputs at the end of a task.
Value Meaning
0 Enable the processing of outputs at the end of the task
Non zero Disable the processing of outputs at the end of the task
Enables or disables the timeout function of an event task.
Value Meaning
0 Disable the timeout function
Non zero Enable the timeout function
Prevents the task from executing. If a task is inhibited, the controller still
prescans the task when the controller transitions from program to run or test
mode.
Value Meaning
0 Enable the task 0 (default)
Non zero Inhibit (disable) the task
Provides the instance number of this task object. Valid values are 0...31.
Time it took to execute this task the last time it was executed. Time is in
microseconds.
The maximum time interval between successive executions of the task. DINT[0]
contains the lower 32 bits of the value; DINT[1] contains the upper 32 bits of the
value. A value of 0 indicates 1 or less executions of the task.
Maximum recorded execution time for this program. Time is in microseconds.
