Setting Message Timers
Device - Parameter - Edit - Message Timer Tab
Note
This procedure is supported by the CS1W-DRM21 and CJ1W-DRM21 only.
A message timer is by default set to 2 s (2000 ms). They can be set 1-ms
increments to between 500 and 30,000 ms.
To change a message timer value, use the following procedure.
1,2,3...
1.
Double-click the node address (#) or select the node address and click the
Edit
Button. The following dialog box will be displayed.
2.
Set the value and click the
OK
Button.
Note To set the same value for all the devices, select the node addresses
and click the
Copy to All Device
Button.
Note
The message timer is used to monitor the time of message communications
(explicit message communications time and FINS message communications
time). The message timer can be set for each destination device indepen-
dently. If the response of a destination device is slow, the timer value must be
set to a larger value. The response may be slow for multilevel FINS message
communications. The next message cannot be sent to the same device until
the response is returned. The DeviceNet master monitors the time-out period
of the message with this timer. The CPU Unit, however, is responsible for
monitoring the response time with the CMND, SEND, and RECV instructions.
Therefore, it is meaningless if only the timer value or monitor time is changed
