KNX CP TP
KNX TP Area and Line Coupler
Line coupler, area coupler, repeater for KNX
Highlights
-
-
Line coupler with galvanic isolation of main and auxiliary line
- - Filter function can be switched off briefly for commissioning (button on the unit)
The KNX TP line coupler KNX CP TP connects two TP lines as main line and subline. KNX CP TP can be used as KNX line coupler and KNX area coupler or KNX repeater (without filtering). KNX CP TP is able to filter the traffic according to the installation place in the bus system hierarchy and according to the built-in filter tables for group-oriented communication. Long messages with up to 240 bytes APDU are supported. Configuring from subline can be deactivated. Special functions for transmission of telegrams are available.
Filtering can be temporarily deactivated on pressing the Function button (Manual Function), i.e. to ease commissioning. KNX CP TP then switches back to normal operation after expiry of a configurable time period. The device is supplied with power by the main line. Operational and filtering states, malfunction and faulty communication are indicated by LEDs. Lines have a galvanic separation between each other.
- Supports extended frames and long telegrams up to 240 bytes APDU length (With all couplers and UIM interfaces long messages e.g. for energy metering applications and visualization purposes can be processed)
- IACK sending on sent out messages is ETS configurable
- When there is no IACK response on the subline, KNX CP TP is able to repeat messages up to three times. Repetition can be configured for both Physical Telegrams and Group Telegrams via ETS
- For an ETS configurable time period, it is possible to switch off telegram filtering by only pressing a button on the device front panel. Without additional ETS download filtering is suspended. This is necessary for running fast diagnostics on site
- Suspending telegram filtering eases commissioning and debugging. When filtering is suspended, temporary access to other lines becomes possible
- Automatic function for switching back to run-time telegram filtering after configurable suspension period (see Manual Mode). This avoids forgetting the reactivation of filtering
- In networks with high busload the internal amount of communication buffers are capable of smoothing peeks in the communication load course
- Database available for ETS4 and higher
