Issue Number: 2
All possible values of S.01.006 are given in the table below.
The network loss detection feature provides a method which ensures that
communication with the master is still present. The SI-DeviceNet resets an internal
timer when a valid message is received from the DeviceNet network, if a message is not
received within the specified period, network loss is detected.
Network loss detection is not enabled internally until cyclic data has been detected. This
prevents spurious network loss timeouts while the DeviceNet master controller is
initializing the DeviceNet network.
Pr S.01.011 determines the action to take when a timeout specified by Pr S.01.010
occurs. All possible actions and descriptions are listed below.
Value Text Description
0 Network OK Network ok/healthy
1 Init OK
The SI-DeviceNet has initialized correctly and is waiting
for the DeviceNet master to initialize communications.
2 No Cyclic
No cyclic data has been recognized. This could be due to
the length of the mapping data is not equal to the master
setup.
3 Init Failed
A part of the SI-DeviceNet initialization sequence was not
successful. If this fault persists after a power-cycle,
replace the SI-DeviceNet.
4 Comm Fault
Fault found in the communications of the module. This
could be due to different devices configured to use
different baud rates.
5 No 24 V No 24 V external PSU has been detected.
6 Baud detecting Automatic baud rate detection is in progress.
7 Initializing The module is currently initializing.
