Serial Port Profiles
Custom Packet
Forwarding
This option allows you to define the packet forwarding rules based on the
packet definition or the frame definition.
Default: Disabled
Packet Definition When enabled, this group of parameters 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.
Default: Enabled
Packet Size The number of bytes that must be received from the serial port before the
packet is transmitted to the network. A value of zero (0) ignores this parameter.
Range: 0-1024 bytes
Default: 0
Idle Time The amount of time, in milliseconds, that must elapse between characters
before the packet is transmitted to the network. A value of zero (0) ignores this
parameter.
Range: 0-65535 ms
Default: 0
Enable Trigger1
Character
When enabled, specifies the character that when received will define when the
packet is ready for transmission. The actual transmission of the packet is based
on the Trigger Forwarding Rule.
Range: hexadecimal 0-FF
Default: 0
Enable Trigger2
Character
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 actual transmission of the packet is based on
the Trigger Forwarding Rule.
Range: hexadecimal 0-FF
Default: 0
Frame Definition When enabled, this group of parameters 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.
Default: Disabled
SOF1 Character When enabled, the Start of Frame character defines the first character of the
frame, any character(s) received before the Start of Frame character is ignored.
Range: hexadecimal 0-FF
Default: 0
SOF2 Character When enabled, creates a sequence of characters that must be received to create
the start of the frame (if the SOF1 character is not immediately followed by the
SOF2 character, the IOLAN waits for another SOF1 character to start the
SOF1/SOF2 character sequence).
Range: hexadecimal 0-FF
Default: 0
