The following parameters must be configured for use. Hardware and flow control configuration
information must match the external device.

During Jog on Path
The user may select whether messages will be sent when jogging Forward or Backward on Path
while at the Pause screen. Note: All messaging will stop when the Stop Key has been pressed or
the Remote Pause input becomes active.
Note: The Message Type 21 will transmit the message concurrent to the associated motion segment
during “Backup on Path”.
Retry on Time Out
For the Message Type 22 (which requires an acknowledgement from the external device after the
message) an automatic retransmit of the message may be sent. The user may select the number of
retries allowed before faulting from a lack of response from the external device. The fault prompt
“Message Error” will be displayed when in a Time Out condition.
Time Out
The Time Out value may be used for the Message Type 22 (which requires an acknowledgement
from the external device after the message) if there is no Time Out value used in the command string
of the program code. Refer to the Delay Time / Time Out information for more information.
