✎Note:

The S7-1200 supports simultaneous connection of three devices.
V-BOX access PLC, use S7 protocol, access PLC TSAP 02.01 (S7-1200 PROFINET interface only supports three connections, the default support), detailed reference to the system manual of S7-1200.
S7-1200 String type, the default first two bytes are used to store the maximum character and valid characters, so the text data will be shifted back one word address. When interacting with the data, what way this address plc is displayed with is unknown. And because of an extra word of data causes us to display the wrong. The solution is if we use String, then the actual data address we want to operate on is actually shifted back two bytes, so as long as the address on the project is shifted back 2 bits to correspond with the actual data address.

How to setting String in PLC and V-net
PLC configuration

choosing Data type--String→add"[]" after String and input data length

V-box configuration

choosing Word and DBxDBW →input Register Main No. →Data format is String →input data length you want to use → choosing Byte order--Little-endian

Note: Register Main No. = offset in PLC + 2
For example, the image above has an offset of 4, so the register Main No. is 10006
If an offset is 8, the register Main No. is 10010

Set Ethernet connection parameter. IP, Subnet Mask, shown as below.

TSAP set: The value set by local TSAP is the remote TSAP set in HMI. PLC's remote TSAP is the opposite, shown as below.

Download Project: Click "Address book" to add the IP address to be downloaded (fi."Detect" to check whether the IP address can be detected. Then click “ok”, and the system will prompt that PLC will be "STOP" mode. Click “YES” to start download.

V-BOX Communication Settings

Set PLC IP in [IP Address] settings;

TSAP setting

The initialization script needs to set the source TSAP address and the target TSAP address, otherwise the communication will not be successful.

You can copy the following script into V-net directly.

function init.main()
addr_setword("@W_0#HSW1200",8192) -- Set the source TSAP address
addr_setword("@W_0#HSW1201",4096) -- Set the destination TSAP address
end

Note:
The name of the test script must be “init”, 8192 and 4096 are the data used for the test, there is no HSW address in the register option, but you can directly set the value of the corresponding address through the code.

✎Note:

Communication port configuration:
- Continuous length needs to be set to 0.
- Integration interval needs to be set to 1. (no change may result in data errors)
- Set Port and Device Station NO.
- Other set as defaulted.
Notes on the use of registers:
- Register VD: Use only registers that are multiples of 4, such as 0, 4, 8, etc.
- Register VW: Use only registers they are multiples of 2, such as 0, 2, 4 etc. (Using an odd-length register may result in data errors, such as 2 3 4 )
