IP communication with APC 7920

Sentenced

Hello people,
this is my first post so ....

The problem:
- i have a APC 7920 UPS and i need to connect to the device via telnet and restart some outputs (Sky1, Sky2, Apple TV, etc...)
- the problem is that when i login to APC with telnet the device has a menu; i have to navigate thru the menu in order to reboot some devices - i attached an image with the APC telnet session;

i have the code below for connecting and restarting devices (for the moment is a testing phase so i restart all)

DEFINE_DEVICE

dvIPPower = 0:5:0  // IP Communication Device
dvPANEL = 10001:1:0	//Touch Panel

DEFINE_VARIABLE

CHAR sIP_CLIENT_BUFFER[20000] 	// for receiving data sent from a server
INTEGER CONNECTED           	// set if IP connection was established

DEFINE_START
CREATE_BUFFER dvIPPower,sIP_CLIENT_BUFFER

IP_CLIENT_OPEN(dvIPPower.Port,'192.168.1.13',23,1)

DEFINE_EVENT

DATA_EVENT[dvIPPower]
{
    ONLINE: // IP Device comes ONLINE, if connection was established on IP level
    {
    CONNECTED = 1
    }
    OFFLINE: // IP Device goes OFFLINE, if connection was closed on IP level 
    {
    CONNECTED = 0
    }
  STRING:
  {
    // operate received data like data of a serial device
  }
  ONERROR: // if an error message comes from IP Connection
  {
    IF(DATA.Number <> 0) // DATA.Number=0 -> no error
    {
      SEND_STRING 0,"'Device ',DEV_TO_STRING(DATA.Device),':',GET_IP_ERROR(DATA.Number),13,10"
    }

  }
}


BUTTON_EVENT[dvPANEL,1] // Device 1 - reboot
{
    PUSH:
    {
	IF ([dvPANEL,1]=1)
	{
	    IP_CLIENT_OPEN(dvIPPower.Port,'192.168.1.13',23,1)		//Go Online
	    IF(CONNECTED)
	    {

                SEND_STRING dvIPPower, "'apc',$0D"   	// password

                SEND_STRING dvIPPower, "'$0D'"          //
		

		IP_CLIENT_CLOSE(dvIPPower.Port)		//Go Offline

	    }
	    [dvPANEL,1]=0
	}
	ELSE
	{
	    IP_CLIENT_OPEN(dvIPPower.Port,'192.168.1.13',23,1)		//Go Offline
	    IF(CONNECTED)
	    {
		
		SEND_STRING dvIPPower, "'apc',$0D"   	// username
                SEND_STRING dvIPPower, "'apc',$0D"   	// password
                SEND_STRING dvIPPower, "'1',$0D"        //

can you tell me where i'm wrong? the APC is not doing nothing ....

For one thing you're calling IP Client Open twice. First in def start and then in your button push, hence the 'error' already in use. For now I would comment out the IP Open in the button push. The telnet session should stay open but if it times out you might have to change things around.

If you decide or need to change the open to a button push then you'll need to do the 'open' and store the command in a var and then send the stored command when you get your online event in your online data event handler. Use that to trigger sending your command. The way the button push is written now you're sending the command before the connection is even made.

Oh and welcome aboard!

The ting is that if a remove the

IP_CLIENT_CLOSE(dvIPPower.Port)

and i press button 1 on the touch panel its doing nothing. But if i press the button again its sends the commands and restarts the output. Then is the same thing :

Line     38 (13:33:45)::  CIpSocketMan::ProcessPLPacket - ClientOpen handle already in use

Any idea? Thank you for your time.

There are timing issues with IP functions, and they vary with the device you are connecting to. It generally takes a few seconds from when you use IP_CLIENT_OPEN to when it is actually online ... and similarly, it takes a while to go offline after an IP_CLIENT_CLOSE. Trying to open a connection while either process is pending will result in that error, because the handle isn't released until the process is finished.

You also might need to do this in steps.

First connect using the IP OPEN, then check your in box (data event string handler) for a prompt from the device. It may send LOGIN: to which you have to reply. You may have to send it your username but you may be able to send both the user & password but you have to do what it wants and expects otherwise it will likely just close the door. Once logged in you can probably issue any command but that may depend on APC's protocol. Opening the port and then sending a much of crap at the device usually doesn't work unless it's Craptron. (that's a joke)

Take it one step at a time, first connect, then get logged in and then try commands. You might want to read and post the APC specs. Then when you have questions someone may have a better chance of giving help that actually matches the requirements of this device.
