Abstract

PURPOSE: To make it possible to set a DVA separately from each PI by installing a DVA setting equipment outside the PI for CE.
CONSTITUTION: B-side first to fifth connector pins 10 of cable connector 9 are used as DVA setting equipment 4 to set DVA value "1001" by wire connection. Consequently, each data from process field 18 is fetched into corresponding PI/O14 by process signal cable 17. In this case, DVAs are set to A to Z correspondingly to process signals respectively. As a result, the DVA value can be set for every process signal cable in comparison with setting dependent upon each PI/O14, so that other erroneous process data can be prevented from being fetched into CPU1 erroneously on a program.
