plc analog io module
Originally small plc logic controller, which is handling the switch. But now the PLC can handle analog signals, but the PLC computing power or weak, so-called analog is the analog computing simple arithmetic or comparison, and some introduced PID operation. So now the PLC can also analog, such as temperature, etc. to control.
Analog scaling
Because the correspondence between A / D (analog / digital), D / A (digital / analog) conversion between, S7-200 CPU internal representation of the external value of the analog signal, a certain mathematical relationship between the two. This relationship is the conversion between analog / numerical quantity.

For example, using a 0 - 20mA analog signal input, the S7-200 CPU inside, 0 - 20mA corresponds to the numerical range 0--32000; for 4 - 20mA signal, the corresponding internal value for 6400--32000.

If there are two sensors, the range is 0 - 16MPa, but one is 0 - 20mA output, and the other is 4 - 20mA output. They are at the same pressure, the different transmitter analog current magnitude, the value in the internal representation S7-200 different. Obviously scaling relationship that exists between the two. The case of the analog output is also roughly the same.

PLC input module

Provides a large number of features, such as user support plc programmable, commissioning and maintenance work.
High-speed execution of instructions:
The minimum instruction execution time of up to 0.01 μs, for the low-end performance of the device and create a new application program.
Floating-point arithmetic:
You can use floating-point operations efficiently even complex arithmetic functions.
User-friendly parameter assignment:
Only a software tool with a unified user interface, you can complete the work of all parameterized modules. This lowers the entry threshold and training costs.
Human Machine Interface (HMI):
PLC's operating system has been integrated with the user friendly interface services. These functions are no longer needed costly programming: SIMATIC HMI systems process data requests to the PLC, small plc to complete the transfer of these data in the desired update time. PLC operating system can autonomously complete the transfer process. And the full use of the same reference numerals and the database.
Diagnostic functions:
Intelligent diagnostic system CPU continuously detection systems, fault information and specific system events (for example, time errors, module failure, etc.) records. Use of environmental buffer record event information, and with a cut-off time, in order to facilitate future troubleshooting.
Password protection:
Use password protection function efficiently and reliably protect user information to prevent unauthorized copying and subject to change.
