In the "Product Focus/Programmable Logic Controllers" article in the February 1998 issue of Control Engineering , two percentage figures were switched from the sections of the pie chart on p. 113 that they should have occupied. However, the data they contain were correct.

In the same article, a table referred to on p. 126 was omitted for space considerations, but the reference to it was not deleted. The table contained the 10 most-cited communications protocols by CE 's survey respondents.See table above as it would have appeared:

In the "More Users Consider Multivariable Transmitters" article in the December 1997 issue of Control Engineering , Yokogawa Industrial Automation was incorrectly named in the circle number section on p. 60. Control Engineering regrets the error.
