Introduction

PML is the AVEVA Programmable Macro Language. You can find details of the language in the Software Customisation Guide and the Software Customisation Reference Manual.

PML functions, objects forms and macros may be encrypted using the tools described in this guide, and once encrypted may be used within the software, but may not easily be read.

Encrypted PML files may be used in any compatible AVEVA program without an additional license (see Using Encrypted Files). The encryption utility described in Using the PML Encryption Utility Program is separately distributed and licensed.

Please note that the encryption used is of limited strength, and is not secure against all possible attacks - for details of the encryptions used, see Encryption Algorithms.

If you have existing encrypted files encrypted with the old encryption type 3 (as used in "Early Adopter" releases of 11.5.SP2 and 11.6.SP4 in 2007), you must re-encrypt the original source to the new encryption type 4 if you wish to use them with 12-series releases, 11.6 Series SP4.9 and above or 11.5 series SP2.11 and above.
