The EtherNet/IP Map configuration consists of the following parameters:
Table 3.10
– EtherNet/IP Map configuration parameters
Parameter
Description
Device
The device name configured in the previous EtherNet/IP Devices tab.
The selected device will be used for executing the communication function.
Function
The user can select one of four functions.
Get
The module will read data from the target EtherNet/IP device by using the Get
Single Attribute CIP function. The received data will be placed into the Data
Table at the
Input Offset
location configured in this tab.
Set
The module will write data to the target EtherNet/IP device by using the Set
Single Attribute CIP function. The data to be written will be retrieved from the
Data Table at the
Output Offset
location configured in this tab.
Set Static
Similar to the Set function above, but the data to be written will be fixed (equal
to the
Static Value
) parameter in this configuration window. This function will
typically be used with the single Scan class which means the PLX51-PBM can
be setup to write the fixed value only once when the target device
communication has been established.
Custom
This function allows the user to use a custom Service and write and read data
in the same transaction. The user will need to see which custom services that
target device supports in that device’s user manual.
Scan
The user can select Scan Class
A
,
B
,
C
or
D
(which was configured in the
EtherNet/IP Devices tab). The specific mapped item will then be executed at
that configured scan class rate.
The user can also select the
S
class which means that the mapped item will
only execute once when communication to the target device is established. If
the target device goes offline, then the mapped items with this class will be re-
armed.
Service
The custom CIP service/function which is only available when the
Custom
function has been selected.
Class, Instance,
Attribute
The CIP class, instance, and attribute of the request message to be sent.
CN In Offset
The location in the Data Table where the received data will be written.
This will only be available for
Get
and
Custom
functions.
Get Length
The length of the data to be received. If the number of bytes received is more
than the Get Length, then the data will
not
be written to the Data Table.
This will only be available for
Get
and
Custom
functions.
CN Out Offset
The location in the Data Table where the data to be written to the target device
will be read from.
This will only be available for
Set
and
Custom
functions.
Set Length
The length of the data to be written.
This will only be available for
Set
and
Custom
functions.
Data Type
The data type of the Static Value.
This will only be available for
Set Static
function.
Static Value
The value to be written to the target device when the
Set Static
function has
been selected.
Note
: When using the SINT Array data type, the values must be entered as
space-delimited hex values. For example: 05 34 2E A1
