A1SD51S is an intelligent communication module used in ANS series,
Can use the AD51H-BASIC language to make online or offline programming on the universal terminal or computer,
Multitasking can also be performed with up to two programs at high speed.
PLC is the use of " sequential scanning, and constantly circulating " way to work A2UCPU Fundamentals Manual A2UCPU Programming Manual.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work A2UCPU Fundamentals Manual A2UCPU Programming Manual A2UCPU

MITSUBISHI PLC protection and chain procedures.
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 initial state display, etc..
MITSUBISHI PLC program simulation debugging
The basic idea oof 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 program A2UCPU Fundamentals Manual A2UCPU Programming Manual A2UCPU Fundamentals Manual A2UCPU Programming Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
