• Two photos were placed incorrectly in the Industrial PC and VME featured listings sections. The photo of Square D's Seriplex Optimizer family of board-style I/O was mistakenly placed with the write-up for Schneider Automation's Magelis HMI product line on p. 25, and vice versa on p. 68. The corrected versions of both products appear in the Products and Software section of this issue.
