WEG DeviceNet CFW500 - P0719 - Devicenet Network Status; P0720 - Devicenet Master Status

NOTE!
The 0 (zero) value disables the word writing. The amount of output words, however, always remains
the same as it was programmed in parameter P0710.
P0719 – DEVICENET NETWORK STATUS
Range: 0 = Offline Default: -
1 = Online, Not Connected
2 = Online, Connected
3 = Timed-out Connection
4 = Connection Failure
5 = Auto-baud
Properties: RO, CAN
Access groups via HMI: NET
Description:
It indicates the status of the DeviceNet network. The next table presents a brief description of those states.
Status
Description
Offline
Device without power supply or not online. Communication cannot
be established.
Online, Not Connected
Device online, but not connected. The slave has successfully
completed the MacID verification procedure. This means that the
configured baud rate is correct (or it has been detected correctly in
case of autobaud) and that there are no other network nodes with
the same address. However, there is no communication with the
master yet in this stage.
Online, Connected
The device is operational and in normal conditions. The master has
allocated a set of I/O type connections with the slave. In this stage
the effective exchange of data by means of I/O type connections
occurs.
Timed-out Connection
One or more I/O type connections have expired.
Connection Failure
It indicates that the slave was not able to enter the network due to
addressing problems or due to the occurrence of bus off. Make
sure the configured address is not used by other device, verify if the
chosen baud rate is correct and make sure there are no installation
problems.
Auto-baud
The equipment is executing the autobaud mechanism.
P0720 – DEVICENET MASTER STATU S
Range: 0 = Run Default: -
1 = Idle
Properties: RO, CAN
Access groups via HMI: NET
Description:
It indicates the DeviceNet network master status. It may be in operation mode (Run) or in configuration mode
(Idle).
When in
Run , reading and writing telegrams are processed normally and updated by the master. When in Idle ,
only the reading telegrams from the slaves are updated by the master. Writing, in this case, remains disabled.
When communication is disabled this parameter does not represent the actual state of the master.
