| 12 | Depend on diffferent format of data.V-Box use different script functions. | ||
| 13 | for example. addr_setshort(addr,num) Function: Write 16-bit signed decimal address | ||
| 14 | addr_getshort(addr) Function:Read 16-bit signed decimal address | ||
| 15 | addr_getword(string addr)Function: Read 16-bit unsigned decimal address | ||

| 29 | |||
| 30 | The following demo shows that when the alarm condition is reached: temp1 > 5 & temp2 >10 & temp3 < 20(lasts more than 5 seconds) , then send an "alarm trigger" sms. | ||
| 31 | |||
| 32 | When the alarm condition is released，then send an "alarm release" sms. Script is as below: | ||
| 33 | |||
| 34 | {{code language="lua"}} | ||
| 35 | function sms.main() | ||
| 36 | ------send condition------ | ||
| 37 | local temp1 = addr_getword("@Temperature1") | ||

| 44 | timer = timer + 1 | ||
| 45 | addr_setword("@Timer",timer) | ||

| 350 | (% style="text-align:center" %) | ||
| 351 | [[image:InputHTTPparameter.png]] | ||

| 478 | |||
| 479 | (% class="mark" %)1.Europe server:eu.v-box.net | ||
| 480 | |||
| 481 | (% class="mark" %)2.Asean server:asean.v-box.net | ||
| 482 | |||
| 483 | Second is for OpenCloud mode.It means V-Box data will transfer to third part server and do not want to store data to WECON server.We call OpenCloud paltform | ||
| 484 | |||
| 485 | OpenCloud platform is used in configuring the script.Then V-Box can connect with third part server. | ||
| 486 | |||
| 487 | Both mode can support script to connect with third part server.the difference: | ||
| 488 | |||
| 489 | (% class="mark" %)1.If you want to store in WECON server ,please use V-NET. | ||
| 490 | |||
| 491 | (% class="mark" %)2.If your server requires SSL certificate to log in,please use OpenCloud.Because only OpenCloud platform can support to upload certificate | ||
