6.2.3 Ethernet
External devices use MC protocol, fixed buffers, random access buffers, data link
instructions, etc. to communicate with the CPU modules of a redundant system.
Partner products including EZ Socket*
1
can also communicate with them through OPS
connection.
Refer to the following manual below for details.
Q-Corresponding Ethernet Interface Module User's Manual (Basic)
* 1: Indicates the FA communication middleware for programmable controllers, servos, robots, NC,
etc. made by Mitsubishi Electric, which consists of the Windows
®
API (Application Programming
Interface). By using EZ Socket, each partner company can easily develop FA-related application
software using FA devices made by Mitsubishi Electric, which operate on Windows
®
personal
computers.
POINT
Ethernet module can be mounted to the main base unit or extension base unit.
Note that dedicated instructions cannot be used when it is mounted to the
extension base unit. When using dedicated instructions, mount it to the main base
unit.
