2.4 Engineering Communications
This section explains engineering communications.
2.4.1 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-
face Card is required in the personal computer.
