How can you determine the "E-Stand" (hardware release) of an operator panel?
The "E-Stand" (product release) identifies products with the same order number but with changes compared with the version as delivered. These can be upwardly compatible enhancement of functions or the use of new components.
The "E-Stand" of an operator panel is given on the rating plate (on the back of the operator panel). There are two different types of rating plate depending on the operator panel:
Fig. 01: Operator panel with "E-Stand" 1
Fig. 02: Operator panel with "E-Stand" 3
The X stands for the first figure in a series and at the same time identifies the "E-Stand". In the figure X, 4, 5, 6, the X stands for the number 3 and thus means "E-Stand" 3.
The changes that lead to the product release concerned are declared in the Change handbook for products on the Support pages. Further Information: http://support.automation.siemens.com/WW/view/en/10805558/133200
