Communication objects General

No.
0
This communication object is enabled when in the parameter window General, page 29, the parameter Send communication
object "In operation" is selected with the option send value 0 cyclically or send value 1 cyclically.
In order to regularly monitor the presence of the Energy Actuator on the ABB i-bus
can be sent cyclically on the bus. As long as the communication object is activated, it sends an in operation telegram.
Telegram value:
1
This communication object is enabled if in parameter window Function, page 35, the parameter Function safety priority 1 is
selected with the option enabled by object value 0 or enabled by object value 1.
The Energy Actuator can receive a 1 bit telegram via this communication object, which another KNX device, e.g. diagnostics
module or wind sensor, sends cyclically.
If the communication object for the monitoring time is activated, the communication capability of the bus or the sensor (signal-
ling device) can be monitored on receipt of the telegram.
If the Energy Actuator does not receive a telegram (value can be programmed) on the communication object Safety priority 1
within a determined period, a fault is assumed and a response programmed in parameter window A: Safety is implemented.
The output of the Energy Actuator goes into a safety state and does not process any telegrams. Only after the communication
object Safety priority 1 again receives a 1 or 0 (depending on the parameterization) incoming telegrams will be processed again
and the contact setting changed.
The monitoring period can be adjusted in the parameter Function via the parameter Control period in seconds.
The Safety priority 1 is also triggered if a telegram with the programmable trigger value is received.

This communication object is enabled if in parameter window General, page 29, the parameter Enable communication object
"Request status values" 1 bit has been selected with option yes.
If a telegram with the value x (x = 0; 1; 0 or 1) is received in the communication object, all status objects are sent on the bus, as
long as these have been programmed with the option on request or after a change or on request. Some status objects are sent
in every case; see the description of the parameter in chapter 3.2.1.
The following function results for the value x = 1:
