MES interface module.
Need MX MESInterface software and CF card.
Easily connect production equipment and information system.
Through the excellent database sharing function, greatly reduce the cost of information.
By direct connection, the connection process of the enterprise system database (such as MES) is simplified.
Module configuration is simple, without any programming.
The data can be monitored in the module side, when a user defined trigger condition occurs,
Will be read in the form of SQL text and send the specified data to the MES HG-JR25K1
The network load can be reduced compared with the previous scheme which is based on the gateway PC to obtain / monitor the data.
Receive information from the MES, perform pre stored SQL tasks.
In addition, the production instructions from the MES are also received,
The production information can be downloaded from the database, and the modification of the formula information can be conveniently carried out. 2 slots.
Can be installed in the power supply unit for A series units installed QnA/.
Cannot extend.
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.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate.
