exceeded, the tool fails and the message data and Actual Timestamp Difference values are not written
to their respective properties.
• Message Number - Enter the desired Message Number in the Message Number field (from 0 to 255).
There should be an Impact Send Message tool in a task in the Camera listed in the Camera field that
uses the same Message Number.
• Enable Maximum Timestamp Difference (ms) - To use this tool with an A, T, or C Series smart
camera, this property must be disabled.
If enabled, this is the maximum time allowed between the trigger of the Send Message task and the
Receive Message task. Use this value to insure that the data being received relates to the current image
being processed. For example, if the time difference is too great, the Send Message task may have
fallen behind and is sending a message from a previous part.
If the difference between the Send task and the Wait task time stamps is greater than this value (in mil-
liseconds), this tool fails.
When the tool passes, the message data received from the corresponding Send Message tool is written
to the Output properties in this tool.
The Actual Time Stamp Difference Output property displays the difference between the two time
stamps if the Timeout property value is not exceeded.
If this property is disabled, the first message with a matching message number is used if the Timeout
property value is not exceeded.
• Actual Timestamp Difference (ms) - This is the number of milliseconds that elapsed between when
the Send Message and the Wait For Message tasks were triggered.
• Camera - The IP Address and name of the camera that contains this tool. You can select and copy this
information from here, then paste it into the Address property or the Setup’s Select Message Destina-
tion dialog of the corresponding Send Message tool.
Serial Port Out
In the Communication Drawer
The Serial Port Out tool sends a string or integer list out the Impact device’s serial port. Impact devices sup-
port only RS-232 communication protocol. RS-485 is not supported. See “Serial Port” on page 2-10 to
define the Serial Port parameters such as speed, parity, and the delimiter for the receiving device.
How to set up the Serial Port Out tool
1. Click the Setup tab, then click the Setup radio button.
Input Name What it is
Input String The string that is sent the serial port when the task runs.
Input List The integer list that is sent the port when the task runs.
Synchronous If True, the Impact device synchronizes the transmission with the receiv-
ing device.
Delimiter Type The delimiter is placed at the end of the input string when it is transmit-
ted. The receiving device or camera’s Serial Port Delimiter must match
this setting. The M-Series processor can use only a one character delim-
iter.
