Overview of CP-217 Transmissions

The 217IF Module is a Serial Transmission Interface Module equipped with two RS-232C
circuits and one RS-422/485 interface circuit. Each interface supports various transmission
protocols, beginning with Yaskawa's own MEMOBUS transmission protocol. The RS-232C
CN1 D-sub 9-pin connector can be used as an engineering port. The MPE720 Programming
Device can be connected to perform MP920 engineering.
This section explains the hardware and software settings that must be made for CP-217
transmissions (serial transmissions). These settings allow the Machine Controller to operate
as a Master or a Slave conforming to each transmission protocol.
CP-217 transmissions can send and receive data using MSG-SND and MSG-RCV functions
programmed in drawing or function programs.
