A1SG60 is an empty cover that is used to plug in the unused I/O slot on the main board or on the extended board.
A1SG60 is a reserved dummy module I/O point to PLC extended I/O system.
With the switch on the module can be set to retain the I/O point,
Can set 16 points, 32 points, 48 points and 64 points A970GOT-SBD Manual A970GOT-SBD User's Manual. DC input points: 2 points.
Input voltage and current: 7mA, DC24V A970GOT-SBD
Input response time: 10ms.
2 point /1 a public side.
Positive / negative sharing.
Output points: 2 points.
Output voltage and current: DC24V/AC240V, 2A/1 point, 4A/1 common end.
Output response time: 2ms.
2 point /1 a public side.
Output form: relay.
16 point terminal station.
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered A970GOT-SBD Manual A970GOT-SBD User's Manual.
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 A970GOT-SBD Manual A970GOT-SBD User's Manual. .
MITSUBISHI 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 the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation. Input and output points: 480 points.
Input / output data points: 480 points.
Program capacity: 8k.
Basic command processing speed (LD command) s:1.25.
RAM memory capacity: 32K, power supply.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
User program storage capacity: it is a measure of how much the user aapplication can store the number of indicators A970GOT-SBD Manual A970GOT-SBD User's Manual.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General llogical operation instructions each account for 1 words A970GOT-SBD Manual A970GOT-SBD User's Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
