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

Hunter 51.1 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.
Leo Wei 1.1 31
Hunter 51.1 32 When the alarm condition is released,then send an  "alarm release" sms. Script is as below:

Leo Wei 1.1 476
477 V-Box have two mode.One is for V-Net,User need to use WECON server to store data.We call this V-NET platform.
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
