Runtime Parameter Update

In order to add, remove or change a SNMP Agent device parameter in runtime, please follow the steps below:

1 - Create a tag named "UpdateConfig". Inform at the Device field any device name (ex: "Teste" - it cannnot be empty) and at the Item field the text "UpdateConfig".

2 - Create at your E3/Power project a script that will change the desired parameters through the IOKIT operation "SetConfigurationParameters" described at Documentation of I/O Interfaces.

The parameter names used by this driver are shown below. They store the configuration performed at the Device Config tab - SNMP Device Config.

ParAMETER	DescriPTION
SNMP.DeviceCount	Indicates the total number of devices. Each device is addressed by an Index starting at 0. The Index is necessary for all other properties.
SNMP.Device[Index].Name	Name of the device informed by the Index. Exemple: SNMP.Device[0].Name = "MainSwitch"
SNMP.Device[Index].IP	IP Address
SNMP.Device[Index].Port	Port
SNMP.Device[Index].Community	Read community
SNMP.Device[Index].WCommunity	Write community
SNMP.Device[Index].Version	SNMP Version
SNMP.Device[Index].MaxReq	Max number of simultaneous requests
SNMP.Device[Index].Modules	List of MIB modules
SNMP.Device[Index].Disable	1 = disables the communication with this device; 0 = enables

At the example script below, we are enabling the communication with the device with Index = 1 and defining it´s IP Address. After sending the parameters through the Write operation at the SetConfigurationParameters tag (-1,0,0,3), we request the configuration update through the write operation at the UpdateConfig tag.

Dim CommArr(1)

CommArr(0) = Array("SNMP.Device[1].Disable",0)

CommArr(1) = Array("SNMP.Device[1].IP","192.168.100.2")

Item("DriverSNMP").Write -1,0,0,3,CommArr

Item("DriverSNMP").Item("UpdateConfig").WriteEx(1)
