|Enabled||Default is set to true.|
|Hostname||The hostname or IP address of the device.|
|Timeout||The request timeout, specified in milliseconds. The default is 2,000.|
|Concurrency||The number of concurrently issued requests allowed. There is a 1:1 correlation between concurrency and the number of CIP connections used.|
|Connection Size||The CIP connection size to use. The default (and maximum) is 1,994 bytes.|
|Slot Number||The slot number in the backplane in which the CPU is located.|
To export variables from Sysmac Studio, navigate to the global variables and select Tools > Export Global Variables > CX-Designer.
The variables will be saved to the clipboard in tab-separated format. You can now paste the contents into an empty text file for use with importing into the Ignition Gateway.
In order to browse Tags in the Designer, you must first create a mapping for the device in the Gateway. The Manage Tags page can be accessed by navigating to the Omron device and clicking the Tags link.
Once on the Manage Tags page, you can manually enter the Tags, or import them from a tab-separated file. When importing, first choose a file, then click the Import button. The default option when importing is to replace the Tags table with Tags from the import. Select the append option to append Tags to the table.
Once you save any changes made to the Tag mapping, you can view the Tags in the Designer OPC Browser.
In the Tags table of the Manage Tags page, we have four columns of configuration per Tag:
Leaving the Elements column blank will result in a scalar Tag. When reading from the device, only one element will be requested.
Specify the number of elements in an array in the form of 0..N . The initial index 0 is always included, so an array mapped with 0..4 elements is a 5 element array.
The number range specified in the Elements field can deviate from the range specified in the device's program. Thus, if an array was configured with a range of 0 - 4, but the mapping on the Ignition Gateway is set to 3 - 7, then the resulting items would be offset as follows:
|PLC Program||Tag in Ignition|
This is because the driver always assumes that the lowest configured element on the mapping page matches up with the lowest element in the PLC program. As seen above, this can cause some confusion if the mapping on the Ignition Gateway is configured with a different range.
For this reason, it is highly recommended to configure the Elements field on the Ignition Gateway to match the range used in the PLC program.
Note, that this also applies to Multidimensional Arrays.
Multidimensional arrays are specified in the same way as arrays with each group of indices separated by a comma.
Array elements may also be specified with a single number equaling the total number of elements.
The number of characters for String variables is specified in the Chars field.
String arrays are mapped using both the Chars and Elements fields.
