MITSUBISHI PLC protection and chain procedures QX21L.
Protection and chain is an indispensable part of the program, must be carefully considered .
It can avoid the control logic confusion caused by illegal operations.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initiaal state display, etc QX21L..
MITSUBIISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of thee prrogram QX21L.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
