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.
