1 Introduction
BoxX 2 series PLC is an upgraded version of old BoxX PLC, which is programmed by the use of a Function Block Diagram. The programming of
BoxX 2 is simpler and easier to learn than that of a conventional PLC, which uses ladder diagrams and associated instructions. In the design
concept of BoxX 2 series products, it adds power indicator, comes with 2-way 485 communication interface, supports standard MODBUS RTU
protocol and can modify parameters and other functions through the LCD panel, which greatly reduces the user’s cost investment, and for
the operation It brings great convenience. The volume of BoxX 2 series products follows the old BoxX 2’s small size, light weight and other
characteristics, and is especially suitable for internal installation and use. Now BoxX 2 are being widely used in many fields such as industry,
commerce, mining, agriculture, home automation, etc.

1.3 BoxX 2 Features
1. Removable LCD display (AF-HMI)
AF-HMI (Removable LCD display) can be used flexibly according to your needs. When you need it, you can install and use the keys on the panel
to query/set the BoxX 2 address, BoxX 2 system time, modify the function block parameters and manually calibrate the analog quantity, etc.
When you don’t need it, you can disassemble it and replace it with an ordinary panel, which will greatly reduce your cost of use. However,
compared with AF-LCD, the AF-HMI operator panel cannot be programmed manually.
2. FB programming and big program storage capacity
BoxX 2 uses a function block to realize the control function that the previous PLC needed a large section of the program to realize, and several
functional blocks are connected in a certain way to complete more complicated control functions. The BoxX 2 can accommodate up to 127
function block programs. There are enough resources for you to implement complicated control requirements. Once the program is written, it
will never be lost. BoxX 2 uses a larger memory capacity chip than BoxX.
3. Exquisite and compact design
If you are looking to make your device delicate, BoxX 2 will be your best partner.
AF-10 Series: 71.6 mm x 90.4 x 57.6 mm
AF-20 Series: 126.4 mm x 90.4 x 57.6 mm
4. Free programming software
The free QUICK II programming software is an extremely friendly human-machine programming interface. It not only can edit function charts,
but also can provide functions such as off-line simulation of your programs and on-line monitoring of I/O status. It solves many inconveniences
such as customer online testing.
5. Real-time clock function
The BoxX 2 has a clock-recording function that can run at any time you need, and you can set up to 127 different time periods, especially for
systems that require time control. The timing is accurate to the second, and BoxX 2’s RTC precision error is greatly improved to 20 s/month
compared with BoxX, making your time control more accurate.
6. Analog inputs
BoxX 2 can receive analog input except for switch input so as to complete the control of temperature, humidity, pressure, flow, liquid level, etc.,
and can monitor the analog value status of the PC through short distance or long distance. And BoxX 2 simulation accuracy and BoxX greatly
improved to 10 (0.1 V).
7. Security password lock function
BoxX 2 has absolute confidentiality for the program you write. You can set your own password before burning the program. You can modify the
application only after entering the correct password. When the AF-HMI panel enters the function interface, it must enter the correct password
and protect it with the * symbol.
8. Power indicator
BoxX 2 adds red power indicator to facilitate the customer to visually check whether the machine is properly connected to the power supply.
When customers use BoxX before, it is necessary to use a multimeter to test the voltage across the power supply to determine whether the
power supply is properly connected to the customer, causing inconvenience to the customer.
9. Communication interface
In addition to downloading the communication port, BoxX 2 also adds two 485 ports to save the cost and space for customers directly. BoxX 2’s
A1B1 interface supports the standard MODBUS RTU protocol and can communicate with other manufacturers’ branded touch screens and other
devices. BoxX 2’s A2B2 interface is used to communicate with our SH300 text display. A detailed description of the communication interface
is given chapter 4.
10. Communication protocol
In addition to the custom protocol for the download port, BoxX 2 adds the standard MODBUS RTU protocol. The old BoxX only supports custom
protocols.

2 Installation and wiring
2.1 Installation
2.1.1 Methods
BoxX 2 is small so it is suitable to be fit inside panels or machinery. The installation of BoxX 2 is extremely easy.
1. Use standard 35 mm DIN rail mounting BoxX 2
2. Use screw mounting holes on BoxX 2 for direct mounting
Figure 2.1 Use stand and DIN rail for installation of BoxX 2
Screw mounting hole
Buckle at the bottom

2.1.2 Dimensions
2.2 Wiring of BoxX 2
Screwdriver with a spade tip width of 3 mm is needed for the wiring of BoxX 2 series. As for the cross section of a wire. The following two sizes
are at choice:
- 1 × 2.5 mm2
- 2 × 1.5 mm2

2.2.1 Connection of power supply
1. For BoxX 2s like AF-10MR-A2 and AF-20MR-A2, its applicable power supply is 100 ~ 240 V AC, 50/60 Hz.
The grid voltage fluctuation range is about 10 %.
2. For BoxX 2s like AF-10MR-D2, AF-20MR-D2, AF-10MT-D2, AF-20MT-D2, AF-10MT-GD2,
AF-20MT-GD2, AF-10MT-E2, AF-20MT-E2, Its applicable power supply voltage is 12 – 24 V DC.
3. For BoxX 2s like AF-10MR-E2 and AF-20MR-E2, its applicable power supply voltage is 12 – 24 V UC.
BoxX 2 series power wiring diagram is as shown in Figure 2.4 and Figure 2.5,
2.2.2 BoxX 2 Input Connection
BoxX 2 input can be either digital switch, such as on/off switches and photoelectric baffle and sunshine switch etc., or analog, such as pressure,
temperature, humidity, flow and so on. The specific requirements are as follows:
Demand AF-10MR-A2
AF-20MR-A2
AF-10/20MR-D2
AF-10/20MT-D2
AF-10/20MT-GD2
AF-10MR-E2
AF-20MR-E2
AF-10MT-E2
AF-20MT-E2
switch status 0 < 40 V AC < 3.5 V DC < 4.5 V UC < 3.5 V DC
Input current < 0.1 mA < 0.4 mA < 0.2 mA < 0.5 mA
switch status 1 85 – 240 V AC 10 – 24 V DC 10 – 24 V UC 10 – 24 V DC
Input current < 0.2 mA < 2.5 mA < 2 mA < 2.5 mA
Proximity switch type with direct input 2-wire system/3-wire system/4-wire
Note:
1. Analog can be input into analog-receivable BoxX 2s like AF-10/20MR-D2, AF-10/20MT-D2, AF-10/20MT-GD2 through all the
input ports (I1-I6/I1-IC). As long as the analog-related function blocks are used in the program, Its port is automatically set to analog
input. If in the program do not use the analog-related function blocks, its port is automatically set to digit input.
2. The analog inputs require 0 ~ 10 V DC voltage signals, which are divided equally in 0.1 V increments. When you edit the program,
all the block parameters related to the analog inputs are based on the minimum increment of 0.1 V.
3. When the input voltage is higher than 10.0 V DC, it can only be used as switch, not be used as analog.
4. For digit input,when the switch state changes from 0 to 1, the time of the 1 state must be greater than 50 ms.
When the switch state changes from 1 to 0, the 0 state must also exist for more than 50 ms.

After the BoxX 2 is powered on, the AF-HMI enters the BoxX 2 status display interface.
Take 10 points as an example, as shown in Figure 3.2,
The I listed above is input: the status of 6 input ports
The following Q is output: status of 4 output ports
(*indicate ON, i.e. status «1», indicates OFF, i.e. status «0»)
The time is displayed under the current day of the week.
3.2 Password confirming
When you observe the AF-HMI in the above status display interface, press the
ESC
and
OK
keys at the same time to enter the password confir-
mation screen, as shown in Figure 3.3, BoxX 2 needs to enter the password value at this time, and the cursor stays at the high position of the
password. You can use the
+
and
–
keys to change the numeric value (0 - 9).
When you press the
+
and
