We commented in the May issue in Books that a few ISA standards needed updating in this seven volume set. This volume is probably one of the most frequently referred to references in the set.

However, some of S5.1 is dated and needs an update to reflect developments with fieldbus and multi-function transmitters, the merging of digital control terminology and emerging developments for STEP, the STandard for the Exchange of Product model data.

By the time the next issue is reviewed it will be some 20 years since the last major update, which was supposed to incorporate S5.3 on graphical symbols.

Nevertheless, the complete set provides a wealth of practical information.
