====== Synapse remote I/O module ======

{{ network:syn_1wire.jpg?direct&200| 7bit Synapse remote I/O module}}

The Synapse module (further reffered to as 'module') is produced under 7bit trademark and designed for data aquisition from discrete sensors and 1-Wire temperature sensors, as well as load control with digital outputs.

The module has 2 Ethernet interfaces (working in a "bridge" mode) for LAN connection and supports **Modbus TCP 
& MQTT protocols**. The enclosure is for panel / DIN 35 mm mount.

==== Modbus registers map ====
There are 1000 HR registers available for the user, some of them are reserverd for special functions:
^Holding Registers^^
| 000-999: (F-RAM) ||

^Discrete Inputs ^^
|DI0 ~ 7| Digital input state 0 ~ 7|
|HR20 ~ 27| Digital filter. (DI 0 ~ 7)|

^Coils ^^
|C0..7| Digital outputs 0..7|
^Safety state ^^
|HR35| Keep previous outputs state after restaft, 0 - off, 1 - on|

^Predictive maintenance registers^^
|HR0 ~ HR14| countung input (DI 0 ~ 7) dw, high word comes first |
|HR60 ~ HR 74|DI 0 ~ 7 time on totalizers |

^PWM for triac outputs^^
|HR111 ~ 118 |DO1 ~ 8 PWM duty cycle |
* this option available for the SSR outputs

^System^^
|HR30| power-ups counter |
|HR31| uptime in seconds (high)|
|HR32| uptime in seconds (low) |

^Temperatures ^^
|IR0 ~ IR31| 1-Wire temperature 1 (-1000° - sensor failed or not connected) |
|HR33      | Total sensors quantity or Init** (writing 0 to HR33 clears the enumeration)|

==== Auto enumeration for 1-Wire sensors ====
Each DS18B20 has their own unique serial number. Using a special search algorithm, the Synapse finds and saves the enumeration scheme for the sensors found in the static memory. New sensors still can be added to the existing enumeration by 
  *powering on or resetting the module
  *writing non-zero value into HR33 register

==== Modbus map csv-file ====
For the convinence, a module register map is provided from this {{network:synapse_all_reg_1wire.zip | link }} to import in the WebHMI project.
