3.4 Planning/Configuring
The SOP flag is set to "1" (true) when the network connection is operating normally, and "0"
(false) when it is not operating normally.
The network status cannot be automatically detected. Instead, a "Pulse Timeout" method is
used to set the network status flags.
The "Pulse Timeout" status detection must be set up in the menu system, and has to be
"strobed" by a network device that is communicating with the drive.
Procedure for Pulse Timeout Setup
1. Pick one of the 62 selectable "Data to Drive" registers and set the pick list item to "Net Input
Pulse".
2. Set parameter 'Network Timeout' (9934) for network 1 and (9935) for network 2, in the
'Config Parameters' menu, to a value (in seconds) to activate the network timeout. 0
seconds = disable timeout.
Pulse Timeout Operation
● A network device must set a unique (different) value into the "Net Input Pulse" register
before an internal timer reaches the "Network Timeout" value.
● If the network device writes a unique value, the network status flag is set to "1" and the
internal timer is reset.
● If the network device fails to write a unique value to the "Net Input Pulse" register before
the internal timer times to the value set by the "Network Timeout" parameter then the status
flag is set to "0".
