There are two ways to connect the acquisition card to MITSUBISHI PLC:
\\
1. Use MITSUBISHI PLC\'s free protocol to connect to the acquisition card.
\\
Protocol details to see the acquisition board card RS232 communication protocol manual, set the serial communication parameters to send read board commands, read back to the PLC data. Provide an example of communication for MITSUBISHI PLC. In addition, the RS485 version can be connected to PLC, with FX2N written by works2 and connected to this card instance. If the user does not specify, the default shipment RS232 communication, 24V power version.

\\
\\


\\
Two. Use the MODBUS-ASCII function in the board card in PLC. Read the data space of PLC directly and write back data to PLC. PLC does not need to have any program. It only needs to put data in the specified D data storage area and can output directly. The collected data will also be directly placed in the corresponding D data area.

\\
\\

Both read and write PLC are 16 D data stores. The default area is d 100 - D 15 15. The read area is d 15 0 - D 16.

\\
\\

Note: because the card is written directly to the PLC data, the card is used as the Modbus host. Therefore, it is not possible to use multiple boards to hang on a RS485 interface. Hanging multiple hosts on the same bus will cause communication errors. So it can only be connected to a card when it is not driven.

74HC244 voltage, current frequency measurement encoder, phase digital IO omnidirectional data acquisition card
\\
The AD7606 AD conversion module is used to achieve 8 road high precision 16 bit true differential ADC analog acquisition. There are two kinds of interfaces for RS232 and SPI, and SPI can realize the sampling speed of each channel 10k/sec in 8 channels. Using spartan6 FPGA to make the main control chip, it will not crash, and it can resist strong interference.
\\
There are many functions on the highly integrated circuit board: 4 digital input (DI X1-X4) and 4 road digital output (DO Y1-Y4), which can be configured as digital IO, frequency measurement and counting, rotary encoder collection, phase acquisition, PWM output, analog input function can be realized by adjusting hardware configuration to real 8 channels current or voltage acquisition, voltage acquisition can be passed. The welding jumper is configured as a single end or a differential mode.
