Customization Facilities; The Programmable Macro Language (PML)

Most modules make use of a Graphical User Interface (GUI) to drive the software. The interfaces provided are designed to apply to a wide range of situations and business needs. However, as you become more experienced they may choose to design an interface which is more closely related to their requirements, the user can do this using AVEVA’s Programmable Macro Language (PML).

For full details of PML, refer to PML Customization and Software Customization Reference.

Before you can begin customizing a GUI, the user must have a good working knowledge of the command syntax for the module they are working with. The commands are described in detail in the reference manuals for the modules.

The ability to customise individual applications to suit the users own specific needs gives the user great flexibility in the ways in which they use their system. But it also introduces the risk that the users modified macros may not be compatible with future versions of the software, since they are no longer under AVEVA’s control. The users own Applications may diverge from future standard versions and may not take advantage of product enhancements incorporated into the standard product. To minimize this risk, it is most important that the users in-house customisation policies constrain any changes which the user makes to the Applications so that they retain maximum compatibility with the standard product at all times. Remember that AVEVA can give the user full technical support only for products over which it has control. It cannot guarantee to solve problems caused by software which the user has written.
