C4 Server
Timeout
This box lets you specify a timeout value (in counts) to
decide whether to turn off the NC power. This box can
be set only when the Enable C4 Server check box is
checked.
Use a default value of 2.
Retry Count
This box lets you specify how many times
communication with the NC is to be attempted after a
request for communication is rejected.
Use a default value of 5.
Re-connection
on
Communication
Error
This box lets you specify whether to make a
reconnection automatically and a reconnection method
if a communication error occurs for a poor
communication line quality. This box can be set only
when the Enable C4 Server check box is checked.
Check Disable (default).
- Disable
Does not make a reconnection automatically.
- Enable
Makes a reconnection automatically. When the quality
of the communication line is poor, another error can
occur soon even if Enable is checked and a
reconnection is made. If a communication error occurs
frequently, do not reply on the reconnection function
but improve the quality of the communication line. Note
that you may be unaware of frequently occurring errors
if Enable is checked. If a reconnection is made using
this function, the log "Retry Connection(1)" is created in
the "CimCNC connection error log".
- Select by Point
Specifies whether to make a reconnection by using the
value of the point FNCmmmpp.F_COM_RETRY (with
mmm representing a 3-digit machine number and pp
representing a 2-digit path number). If a communication
error occurs, i CELL sets the point to True. To make a
reconnection, set the point to False. If a reconnection is
made using this function, the log "Retry Connection(2)"
is created in the "CimCNC connection error log". When
using this function, the user needs to add a script that
monitors the point and sets the point to False when the
point is set to True.
Retry Interval
This box lets you specify an interval between retries for
communication with the NC to be made after a request
for communication is rejected.
Use a default value of 500.
