1.1. Communication Objects
LC100 has no KNX communication objects.
1.2. LC1000 as Programming Interface
LC100 can be used together with the ETS as a programming interface. The device provides an additional
physical address for this purpose which can be used for a line coupling or repeating.
1.3. Feature Summary
- LC100 supports extended frames and long telegrams up to 240 bytes APDU length. (With all MEC
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, LC100 is able to repeat messages up to three times.
Repetitions can be configured for both Physical Telegrams and Group Telegrams via ETS (to ease
troubleshooting). E.g. after an IACK response no repetition is following and the negative IACK/BUSY
failure mechanism is maintained.
- 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.
- LC100
’s ETS database entries are available for ETS4 and later.
