Is it possible to edit or reset the pulse value of the MR-SI4?
Yes, there is an object with a changeable value and an object with an unalterable value.
BMT-SI4 BACnet MS/TP
Description
The BACnet MS/TP module with 4 S0 inputs according to DIN EN 62053-31 class A was developed for decentralized switching tasks. It is suitable, among other things, for counting S0 counter pulses. This allows very good integration of the module into an energy controlling system. In case of a power failure, the last counter readings are saved. The inputs can be scanned by means of standard objects via a BACnet client. When using the Accumulator Object, pulses up to 50 Hz can be counted, when using the PulseConverter object, pulses up to 500 Hz can be counted. Module address and bit rate are set with two rotary switches on the front. Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.

FAQ's
What can I do if the red ERROR LED on the module lights up or there is no communication?
There are several possible causes, please check the following:
- Operating voltage (A1 / A2) connected and sufficient for the device.
- BUS (A- / B+) connected and not reversed. Pay attention to (- / +), not to A/B.
- Address (rotary switches) set correctly, must not occur twice or be 0.
- Bit rate (rotary switches) set correctly, only possible in programming mode (see mounting note).
- Shielded and twisted pair cable used.
- Termination resistor (120 Ω) set on both sides.
- Bias resistors available once on the BUS.
- Max Master as high as the number of physical master I/Os on the BUS.
- Max Frame high enough for all answers from participants to get through (BMT-RTR setting).
