1.5.2

DPT_Channel X Force Out (1.001 Switch)

The DPT_Channel X

level, as shown in the table below, regardless of the selected Channel function and the previous output status.

The channel status is set on the value defined by the PAR_Value Force Out parameter if the device receives

the message with value On and is maintained until the DPT_Channel X

with the value Off or a higher priority message is sent to the device. In the forcing state the reception of

messages different from DPT_Channel ALL

by the device and will not have any effect on Changing Channel status. These messages will then be sent back

when the forcing ceases by receiving the DPT_Channel X

Status and DPT_Channel X - Status Inverted messages, activating the forcing status, will always be sent by

the device if they are used in group addresses. By receiving the DPT_Channel X

the channel status remains the one acquired on forcing, until the device gets a message that make it Switch,

except for the case where the channel function is "Stairs lights" that, if lights were lit by forcing, they will turn

off after the period set with the PAR_Stairs Light Time (s) parameter.

1.5.3

DPT_Channel ALL Force ALL Out (1.001 Switch)

The DPT_Channel ALL

outputs have to be forced with the highest priority in the status defined by the PAR_Value Force ALL Out

parameter. In the forcing status the reception of messages different from DPT_Channel ALL

will be ignored by the device and will not have any effect on changing the Channel status. These messages

will then be sent back when the forcing ceases by receiving the DPT_Channel ALL

message. In order to avoid bus overloading by sending datagrams after the activation of the forcing status,

pairs of DPT_Channel X - Status and DPT_Channel X - Status Inverted messages will be sent every 100ms,

starting from Channel 1. The status messages are always sent at the activation of the high priority forcing

independently by of the status of the channels, if any used in the group addresses.

By receiving the DPT_Channel ALL

one acquired on forcing, until the device gets a message that make it Switch, except for the case where the

channel function is "Stairs lights" that, if lights were lit by forcing, they will turn off after the period set with the

PAR_Stairs Light Time (s) parameter.
