Appendix 10.2 When Visual C++ ® .Net Is Used (Redundant System) - Mitsubishi Electric QJ71E71-100 User Manual

Appendix 10.2
This section describes the program execution environment, data communication details, and a sample program
for when Visual C++
(1) Execution environment of the program example
(a) CPU module side
A model name of the QCPU in the E71-mounted station
E71 I/O signal
E71 IP address
E71 port number
Programming tool setting
(b) Connected device side
Operation environment
Ethernet interface board model name
Library
Software development environment
MAC address
IP address
Port number
(c) Communication protocol
TCP/IP is used.
(2) Outline of the program example
(a) Program on the CPU module side
Because parameters are set on a programming tool, no program is required.
(b) Program on the connected device side
Write data to the data registers D0 to D4 (five points) of the redundant CPU (control system) in word units using
the library described above. If data write from the system A side fails due to a communication error or other
reasons at this time, data are written from the system B side to the data registers of the redundant CPU (control
system).
