Select “Static input word” and “Static output word” from the hardware catalog and then drag and
drop it to the COM-JG rack detail window. 1/2/4/8/16 words are available.
In this example, the number of data of “Number of continuous accesses” is “4” (there are four
modules) and the number of read and write items is one each. Thus four words are set for both
read and write.
Always locate “Static input word” above “Static output word” on the rack detail
window.
Select and then set the number of word of the COM-JG initial setting from among 1, 2, 4,
8 and 16 words so that the total number of words becomes the same as “Number of
communication items
×
Number of read (or write) items.”
For example, if “Number of communication items
×
Number of read items.” Corresponds
to five words, select one word and four words.
