1 Interface Description

1.1 Data type definition

1.2 Built-in function library clipping

Full features supported: coroutine/debug/ math/ package/ string/ table/ utf8

_{Some features supported (available in []): os[clock/ date/ difftime/ time]}

_{Not supported: io/ file}

1.3 Return value description

The function return type multi means multiple return values (at least 2), usually:

_{1st: nil;}

_{2nd: the error message;}

Assume the function prototype:

Comment

1.string name indicates that the first parameter name is a string

2.number age indicates that the second parameter age is numeric

3. [, number class] indicates that the third parameter class is a numeric value, and it is optional. Specify the default class in class 1 in the parameter description.

4. Any parameter in the brackets of [] is considered to be an optional parameter, and may not be transmitted when called. The default value will be given in the parameter description.

Call example

Output results

Comment

1.From the print result, the second line of the first line is successfully called and returns true; the third line fails the call, the error message is translated as: the bar student has been registered, and there is indeed an error in the code.

2.The fourth line of code uses two variables to receive the return value. The call failed, the first variable stat is nil, and the second variable err stores the error message. Then print it out using print, which is the output of the third line. This example shows how to capture and view the error message.

1.5 Modification of the Print Function

For the convenience of remote development, the print data is sent to the front end (web page) by means of network transmission, and the user can see the result of the debug output, because it consumes certain data and occupies the bandwidth of the server (or occupies server resources). So make the following restrictions:

1.Interval limit: When debugging, transfer once every 2~3 seconds;

2.Data limit: The transfer data cannot be larger than 1.5KB, and the extra part will be ignored;

3.Transmission limit: The data transmission will be stopped automatically after the debugging windows is not closed normally. Only when it is in the debugging window and the switch is on, there is data transmission;

Users should pay attention to avoid printing a lot of useless information, should minimize the debug output

In addition, please refer to the front-end documentation for how to use view debugging.

• If HLword enters any other value, it will be treated as invalid.

Operations on the serial port such as read, write, etc. must use ':' for full mode calls, ie operations on an open serial object.

Serial port name and mode:

The serial port configured in the communication configuration window cannot be configured again using the script. RS232 and RS458 (or RS422) can be used simultaneously, but RS422 and RS485 are mutually exclusive.For example, when the communication port is configured with COM1-485, the script can only open COM1-232, but not COM1-485/422. Similarly, when the communication port is configured with COM2-485, the script can only open COM2-232, but not COM2-485.

Attempting to use a script to open a serial port in an unsupported mode will result in an error directly, as below

Data bit:

1. When the data bit is 7, the maximum value of data transmission is 127 (0x7F), and non-ASCII characters will be truncated, resulting in data errors and garbled characters.
2. When the data bit is 8, the maximum value of data transmission is 255 (0xFF), which supports the transmission of any character.

Function:

Enable one serial port

Parameters:

Setup is a Lua table; it needs to contain the following fields

String setup.name, serial port name, such as: COM1/COM2 (requires uppercase)

number setup.mode, mode: RS232/RS485/RS422

number setup.baud_rate, such as 115200

Operations on MQTT such as connect, subscribe, etc. must use ':' for full mode calls, that is, operate on a created MQTT object.

Both MQTT subscriptions and publications are asynchronous implementations that require the user to implement a callback function.

QoS value:

0: Only push messages once, messages may be lost or duplicated. It can be used for environmental sensor data, it doesn't matter if lose a record, because there will be a second push message soon. This method is mainly used for normal APP push, but if the user smart device is not connected when the message is pushed, the message will be discarded, and the smart device will not be received when it is networked again.

1: The message is delivered at least once, but the message may be delivered repeatedly.

2: The message was delivered exactly once. This level can be used in a billing system. In a billing system, repeated or missing messages can lead to incorrect results. This highest quality message push service can also be used for instant messaging APP pushes, ensuring that users only receive messages once.

Retain flag:

0: not reserved;

1: reserved

Function:

Create an MQTT object

• 1: WIFI
• 2: 4G
• 3: 2G

number [conn.keepalive=60], keep connected heartbeat interval, in seconds

number [conn.cleansession=1], empty the session as described below:

This function is used to control the behavior when connecting and disconnecting, and the client and server will retain the session information. This information is used to guarantee "at least once" and "accurately once" delivery, as well as the subject of the client subscription, the user can choose to keep or ignore the session message, set as follows:

• 1 (Empty): If a session exists and is 1, the previous session messages on the client and server are emptied.
• 0 (reserved): Conversely, both the client and the server use the previous session. If the previous session does not exist, start a new session.

Network communication includes Http request interface, this document does not provide interface description, please refer to the online document for how to use it.

http://w3.impa.br/~diego/software/luasocket/http.html#request

The internal registers of the box are divided into bit addresses and word addresses, which can be accessed in two ways (taking HDW as an example):

1. Access by word, prefix @W_HDW,

For example: @W_HDW0 represents the first word of the system data area, @W_HDW1 represents the second word of the system data area.

2. Access in bit mode, the prefix is @B_HDX, the number in front of "." indicates the number of the word, and the number behind is the bit number of the word.

For example: @B_HDX1020.12, its meaning is to access the system data area in bit mode, the specific location is the 13th bit of the 1020th word.

✎Note: 

1. The address in @B_HDX is taken from the word in @W_HDW, so pay special attention when using the address.

For example, @B_HDX1020.12 is to access the 13th bit of the 1020th word. The value of this bit is the same as the word obtained by @W_HDW001020. The 13th bit of this word is actually the same bit as @B_HDX1020.12.

2.The address of the bit address @B_HDX has a decimal point, while the word address is an integer.

The system storage area (HDW) of the V-BOX is used to store temporary data:

1. Access by word, the number range is: "@W_HDW0"-"@W_HDW299999".

2. Access in bit mode, the number range is: "@B_HDX0.0"-"@B_HDX299999.15".

✎Note: 

HSW is a system special register, so please refer to the system special register table during use. Do not use addresses that are not mentioned in the table, and use the addresses stated in the table with caution (example: restart ("@W_HSW0") Writing a value of 1 will cause V-BOX to restart).

Without any conditions. Direct use ("@W_HSW0") will cause the V-BOX to restart continuously. When using ("@W_HSW0") address, please add judgment conditions, such as: connection to MQTT fails, there is no network, the value of a PLC address meets the condition or counts to a certain value.

1.The system data area (HSW) of the box is used for system special registers (system reserved). Use addr_getword to obtain the following register information:

2. Other

2.1 Access password: addr_getstring("@W_HSW27", 16)

2.2 Machine code: addr_getstring("@W_HSW60", 64)
