Overview

The engineering communications protocol is used between the MPE720 Programming
Device and Machine Controllers. If this communications mode is supported by the Commu-
nications Module, engineering is enabled by directly connecting the MPE720 to a Machine
Controller.
The following table shows the channels that can currently be used as engineering ports.

Note: 1. Yes: Can be used as an engineering port.
No: Cannot be used as an engineering port.
2. If engineering is performed via a 215IF Module, a 215IF I/F Card
is required in the personal computer.
3. If engineering is performed via a 218IF Module, an Ethernet Inter-
