Initial Value for System Memory
Click the System Memory List Button on the Initial Tab Page to display the Initial Value for System
Memory Dialog Box.
The $SB and $SW can be set to communicate with the PLC allocation addresses set in the Initial Tab
Page.
$SB and $SW addresses are divided into functional groups, and the user can select the groups for
which to perform communications. By selecting items, communications will be performed between the
selected area and the PLC address.
The default setting is for only Screen (communications with $SW0). Change the settings as required.
The above setting example is set for communications as follows:
$SW0 Serial A: DM 01000
$SW10 to $SW13 Serial A: DM 01010 to DM 01013
Reference
♦ The $SB bits and $SW words that are not selected in the Initial Value for the System Memory Dia-
log Box are set to not communicate with the PLC, and can be used. (When bits and words are not
selected, it does not indicate that their use is prohibited.)
