Transfer mode from PLC:
Specifies the EtherNet/IP transfer mode from the PLC for this
port.
–
When
Write Msg
is selected, the PLC writes the data to the GW EIP/ASCII... by way of
an MSH instruction.
–
The
Class 1
setting configures the PLC to maintain a Class 1 connection with the
GW EIP/ASCII... which provides cyclic receive (to PLC) and transmit (from PLC) data
between the PLC and the GW EIP/ASCII....
Class 1 communication is only applicable to ControlLogix PLCs. The default is
Class 1
.
PLC IP address:
Enter the IP address of the PLC EtherNet/IP card. The PLC IP address
only applies when
Write to Tag/File
is selected.
PLC controller slot number:
Specifies the slot number on the PLC where the controller
resides. The slot numbers typically start at zero for the first slot. This is only required for the
ControlLogix family of PLCs when
Write to Tag/File
is selected.
Maximum PLC update rate:
The maximum rate (in milliseconds) at which messages are
sent to the PLC tag when the “Transfer mode to PLC” field is set to
Write to Tag/File
or
Class 1
. When
Write to Tag/File
is selected, this setting configures the GW EIP/ASCII...
to space the messages to the EtherNet/IP PLC in order to prevent overwriting data before
the PLC can process it. When
Class 1
is selected, it specifies the fastest acceptable cycle
time between the PLC and the GW EIP/ASCII....
Maximum RX packet size:
When
Write to Tag/File
or
Polling
in the “Transfer mode to
PLC” field are selected, this setting specifies the maximum acceptable size of a received
serial or Ethernet packet. The default value is 1518 bytes for serial ports. When
Class 1
is
selected in the “Transfer mode to PLC” field, this setting specifies the size of the data block
used in the corresponding input assembly instance. The length of the corresponding
instance is equal to (RX data packet size + 4 bytes).
Maximum TX packet size:
Specifies the size of the data block used in the corresponding
output assembly instance. The length of the corresponding instance is equal to
TX data packet size + 4 bytes
Oversized packets:
Specifies how to process oversized received packets. Set the “Max
packet size” field to the desired size and the packet is truncated. Alternatively, the packet
may be dropped.
RX produced data tag name:
Enter the PLC tag or file name in this field. This designates
where to write received data when
Write to Tag/File
option is selected. This field supports
a name containing up to 40 characters. The “Tag/file” name must be a global variable in the
PLC. Enter the tag/file name exactly as it is in the PLC. A MicroLogix type file name must be
N10 or greater and have the format N10:0.
Polling
and
Class 1
methods do not use this attribute.
Polling
and
Class 1
methods do not use this attribute.
This setting is only used when
Class 1
is selected in the “Transfer mode to PLC” field.
The
Polling method
does not use this attribute.
