EIWM and RVM Files

Common Functionality

AVEVA NET Gateway for AVEVA IE&D : EIWM and RVM Files

The exported output is dependent on the element types selected in the configuration and the elements selected for export, for example:

•

If a PIPE element type is selected in the configuration and a SITE element is selected for export, all the PIPE elements in the SITE are exported.

•

If a PIPE element type is selected in the configuration and a PIPE element is selected for export, only the PIPE element is exported.

•

If a SITE element type is selected in the configuration and a PIPE element is selected for export, no output is produced and an error message is written to the log file.

The examples are illustrated in the following table.


Selection in Configuration	Selection for Export	Expected Output
		An EIWM file for each of the PIPE elements in /SITE-PIPING-AREA01 is generated.
		An EIWM file for only the PIPE element /100-B-1 is generated.
		This is an invalid selection. No output is generated and an error message is written to the log file.

•

If an EQUIPMENT element is exported and an RVM file is selected for generation, an EIWM file and an RVM file are generated for the equipment.

•

If a SITE element is exported and an RVM file at the EQUIPMENT level is selected for generation, an EIWM file and an RVM file for each EQUIPMENT element in the SITE is generated.

The examples are illustrated in the following table.


Selection in Configuration	Selection for Export	Expected Output
		An EIWM file and an RVM file for EQUIPMENT /D1201 are generated.
		An EIWM and an RVM for each of the EQUIPMENT elements present in the SITE /SITE-EQUIPMENT-AREA01 are generated.

The RVM file is always generated at the highest selected parent level in the configuration. However, if child elements types are selected in the configuration, the child elements are automatically included in the RVM for example:

•

If SITE and PIPE element types are selected in the configuration and an RVM file is selected for generation at the SITE level, the PIPE element type cannot be selected for RVM. However, if the SITE element is selected for export, the generated RVM includes the PIPE elements.

The example is illustrated in the following table.


Selection in Configuration	Selection for Export	Expected Output
		An EIWM file for the SITE /SITE-PIPING-AREA01 that includes information about all the PIPE elements in the SITE is generated. An RVM for the SITE /SITE-PIPING-AREA01 that includes all the PIPE elements in the SITE is generated.

The EIWM file and the RVM file(s) are associated to each other using the is identified by association. The exception is that the EIWM file does not include any associations between the elements by default. To view associations between elements in AVEVA NET™, specify the associations explicitly using the Associations part of the AVEVA NET Gateway Config window. Refer to Associations for further information.
