Using this Manual
Please read this manual to ensure correct usage of the MP900-Series system. Keep this man-
ual in a safe place for future reference.
Overview
This manual describes the Communications Modules designed for MP900-Series Machine
Controllers.
The following Communications Modules can be used with MP900-Series Machine Control-
lers.
• 215IF (for realtime core networks)
• 217IF (for serial, RS-422/485 networks)
• 218IF (for Ethernet networks)
This manual describes the following items required to use these Communications Modules.
• Communications Module setup
• Communications protocols
• Communications messages
• Communications programming examples
Read this manual carefully when building a communications system or network around
MP900-Series Machine Controllers. Also, keep this manual in a safe place so that it can be
referred to whenever necessary.
Intended Audience
This manual is intended for the following users.
• Those responsible for estimating the MP920 system
• Those responsible for deciding whether to apply the MP920 system
• Those responsible for designing the MP920 system so that it can be mounted in the con-
trol and operating panels
• Those responsible for making, inspecting, testing, adjusting, and maintaining the control
and operating panels in which the MP920 is mounted
Basic Terms
Unless otherwise specified, the following definitions are used:
• MP920 = MP920 Machine Controller, which consists of a Power Supply Module, CPU
Module, I/O Modules, and other Modules
• PC: Programmable Logic Controller
• PP: Programming Panel
• MPE720: The Programming Device Software or a Programming Device (i.e., a personal
computer) running the Programming Device Software
• PLC = Programmable Logic Controller
• “” in “MOV [axis1]...” represents numeric data for axis 1.
