Chapter 6 Data Communications Using The Predefined Protocol - Mitsubishi L02CPU User Manual

CHAPTER 6
The predefined protocol function sends and receives packets predefined by using GX Works2, enabling easy
communications with external devices (such as measuring instruments and bar code readers). Protocols can be either
selected from the prepared predefined protocol library, or created and edited by users.
1) Setting protocols
Protocols can be set easily using the predefined
protocol support function of GX Works2.
