手册就有关与MELSEC-A系列之CPU单元(下面简称为程控器CPU)组合使用的AIS68AD型模拟／数字变换模块(下面简称为AIS68AD)的规格、使用、编程方法等进行说明。
AIS68AD是能够将来自程控器外部的模拟信号（电压或电流输入）变换成数字值的模块，这种数字值是带16位符号的BIN数据。说明了QJ71C24 (-R2)串行通讯模块的规格，以及起动操作顺序、维护、检查、与外部设备进行数据通讯的方式和故障诊断及排除。
Q系列C24是连接Q系列PLC CPU和外部设备的模块，通过使用RS-232或RS-422/485串行通讯电缆，来实现下述的数据通讯。通过使用调制解调器／端子适配器，可以使用一条公共电缆（模拟／数字）与远地进行数据通讯
Glossary
Process station:
This term is used to describe AC800F controllers (field controllers) and rack-mounted controllers. A process station can be designed to be redundant
configuration and non-redundant configuration.
AC800F :
This term is used to describe the AC800F Field Controller type of process station. A redundant process station consists of 2
AC800F controller.
Rack mounted process station:
This term is used to describe a rack-mounted type of process station. A redundant process station contains 2 rack-mounted CPUs.
This term is used to describe a single, non-redundant process station.
In the investment of modern automation system, due to the hardware equipment department
It only takes up less cost in the whole system, then write engineering applications
The cost of software becomes increasingly important. Generally speaking, a self
The engineering application software cost of the automation project accounts for about the entire project.
About 50%, it is not difficult to see that the migration of cost structure creates a lot of innovation for users.
Create an opportunity to optimize project investment, therefore, it is necessary to start from engineering programming
Think about lowering costs in the first place!
This is what we developed the Freelance 800F system for:
Keeping hardware prices consistent with those of programmable logic controllers
In this way, cost efficiency can be improved by reducing user engineering costs.
How the Freelance 800F process control system helps users reduce
Low engineering cost?
●By using a complete engineering tool (Control Builder
F) to configure the entire control system, including automation functions
function, operator interface display and logging, and configuration of the fieldbus.
equipment (PROFIBUS, FOUNDATION Fieldbus,
HART, etc.) and device parameter settings.
● Automatic generation of global data between the process control station and the operator station
According to communication.
For field devices, process control stations and operator stations, a unified global database is used for the entire control system, thereby reducing
cost and time investment in establishing data communication and interactive access.
And ensure the consistency of data throughout the system.
●Provide system-wide unified inspection of user applications, overriding
from process control stations, operator stations to intelligent field devices, including
Including the integrity and consistency check of the user program.
●The programming language strictly complies with the international standard of IEC61131-3, and has
