Packet Forwarding Commands
delay-between-messages
The minimum time, in milliseconds, between messages that must pass before the data is
forwarded by the IOLAN. The range is 0-65535. The default is 250 ms.
custom-on-specific-events
This section allows you to set a variety of packet definition options. The first criteria
that is met causes the packet to be transmitted. For example, if you set a
Force
Transmit Timer
of 1000 ms and a Packet Size of 100 bytes, whichever criteria is met
first is what will cause the packet to be transmitted.
custom-on-frame-definition
This section allows you to control the frame that is transmitted by defining the start and
end of frame character(s). If the internal buffer (1024 bytes) is full before the EOF
character(s) are received, the packet will be transmitted and the EOF character(s) search
will continue. The default frame definition is SOF=00 and EOF=00.
enable-end-trigger1
Enable or disable the end trigger1 hex character.
enable-end-trigger2
Enable or disable the end trigger2 hex character.
enable-end-eof1
Enable or disable the eof1 (end of frame) hex character.
enable-end-eof2
Enable or disable the eof2 (end of frame) hex character.
enable-end-sof1
Enable or disable the sof1 (start of frame) hex character.
enable-end-sof2
Enable or disable the sof2 (start of frame) hex character.
end-trigger1
When enabled, specifies the character that when received will define when the packet is
ready for transmission. The transmission of the packet is based on the Trigger
Forwarding Rule. Valid values are in hex 0-FF. The default is 0.
end-trigger2
When enabled, creates a sequence of characters that must be received to specify when
the packet is ready for transmission (if the End Trigger1 character is not immediately
followed by the End Trigger2 character, the IOLAN waits for another End Trigger1
character to start the End Trigger1/End Trigger2 character sequence). The transmission
of the packet is based on the Trigger Forwarding Rule. Valid values are in hex 0-FF.
The default is 0.
eof1
Specifies the End of Frame character, which defines when the frame is ready to be
transmitted. The transmission of the frame is based on the Trigger Forwarding Rule.
Valid values are in hex 0-FF. The default is 0.
