Explicit Message
AnExplicit message is a point-to-point, request/response-type communication.
System Configuration on PLC
Use the configuration tool to code an Explicit message as an MSG instruction in the
control logic. In the MSG instruction, set all the information including a target device,
targetregister,andread/write.DownloadthecreatedcontrollogictoaPLCandexecute
it.
OntheDX,
thedatacounttobeaccessedperMSGinstructionshouldbe100orless.
In Case of PLC-2, PLC-5, and SLC
• Commands
 WhencreatinganMSGinstruction,specifyacommand.TheDXsupportsthefollowing
commands:
Target PLC Command name
PLC-2 PLC2UnprotectedRead/Write
PLC-5 PLC5
WordRange
Read/Write
PLC5TypedRead/Write
SLC SLCTypedRead/Write
• Specification of data to be accessed
 SpecifywhichofthedataintheDXshouldbeaccessed.ThePLC-2,PLC-5,andSLC
manage data to be accessed in units of "files."
For an external input channel, separate access destinations are used for reading and
writing.
