280 280  * The S7-1200 supports simultaneous connection of three devices.
281 281  * 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.
282 282  * 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.
283 -* V-BOX operation character length needs to be set to 2 times the length of the Siemens character for proper display
