Channel 1 switch
position
EIS 1, 1-Bit
DTP 1.001
C, W, T, U
Receives the current 1-bit switching telegram of the channel to be recorded, e.g. from a
switching actuator.
If the switch positions are recalled cyclically, ensure that on the recalling device, e.g. a switch
actuator channel, the R flag is set in the communication object to be recalled. Otherwise the
Data Logging Unit can not recall the switch position.
1 Number Channel
1
operating
hours
EIS 11, 4 bytes
DTP 12.001
C, R, W, T
Contains the current number (= counter value) of operating hours
With a bus voltage failure the current counter value is saved in the BDB/S.
Via the parameter
Overwrite saved counter values with download
and the option
yes
a further
parameter
Operating hours new counter value after download
opens.
A new counter value can be defined with this.
The counter value can also be modified via the bus.
Before the current values can be changed, the communication object “Enable delete/overwrite
- System” must receive a “1”.
2 Change/read Channel
1
operating
hours start/limit value
EIS 11, 4 bytes
DTP 12.001
C, R, W, T
The operating hours start or limit value can be changed via the bus.
The communication object is always visible.
On bus voltage failure with modified operating hours start or limit value is saved in BDB/S.
Only after a renewed download of the application program is the start or limit value – if set –
is overwritten.
Before the start or limit values are changed “1” must be received on the communications
object “Enable delete/overwrite - System”.
3 Alarm Channel
1
operating
hours
EIS 1, 1-Bit
DTP 1.001
C, R, T
Sends a “1”, as soon as the set operating hours limit value is reached when counting upwards.
When counting downwards a “1” is sent as soon as zero is reached.
As soon as the communication object
248 Send all operating data – System
receives a “1”,
the communication object
Channel 1 operating hours – Alarm
is sent.
Telegram value “1” = limit value reached
Telegram value “0” = limit value not reached
