DPT_Channel X Select Scene (18.001 DPT_Scene Control)

Typically, the scenarios are used to set a predetermined channels configuration of the device, when the

function (direct, logical or analog

scenario for the Channel X. The DPT assigned to this message is 18.001.

User can set up to four different scenarios for each individual channel. If the channel scenarios are enabled

through the PAR_Enable Scenes parameter, the scenarios configuration page appears, on which will include

the relevant parameters. The number that can be set as scenario

parameter

scenario has no effect because even if it was enabled, it is not assigned any numbers. In this way the user has

the option to configure only the scenarios that actually will use. Channel status on scenario Y will be set by the

the PAR_Scene Y Value parameter will update with the current status of the channel set by the user and to

store it for the next recall of scenario Y.

DPT_Channel X - Status e DPT_Channel X - Status Inverted (1.001 Switch)

The DPT_Channel X - Status and DPT_Channel X - Status Inverted messages are relayed from the device on

the bus every time Channel X status switches, as shown in the previous figures.

1.5.6

DPT_Channel X - Logic Input 1 e DPT_Channel X - Logic Input 2 (1.002 Boolean)

If the PAR_Enable Logic Function

the DPT_Channel X - Logic Input 1 and DPT_Channel X - Logic Input 2 messages appear on device

descriptor only if the PAR_Logic Operator parameter is set to AND, OR, XOR. They are the Boolean values to

be sent to the device and that will be composed with the DPT_Channel X Set ON/OFF message for channel

switching.

DPT_Channel X Lock PORT (1.002 Boolean)

If the PAR_Enable Logic Function

that the message must have to lock the logic function PORT formed with the input channel switching.

The DPT_Channel X

accordance with the selected function, only if device has not received previously the DPT_Channel X

PORT message with the value set by the PAR_Value PORT Locked parameter. Otherwise the channel status

preserves the value it had before the switching request, meaning that all DPT_Channel X

messages received after locking the PORT will not be considered by the device.

1.5.8

DPT_Channel X - High Threshold and DPT_Channel X - Low Threshold (7.001Value_2_Ucount)

These messages allow to change run-time the thresholds set by the PAR_Upper Threshold and PAR_Lower

Threshold parameters without overwriting them. They only appear on the device descriptor if the
