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 protocol. The enclosure is for panel / DIN 35 mm mount.

Discrete Inputs: DI 0-7 Coils: DO 0-7
Holding Registers: 0-999 000-999: (F-RAM) 000 - countung input (DI 0) high 001 - counting input (DI 0) low 002 - countung input (DI 1) high 003 - counting input (DI 1) low … 014 - countung input (DI 7) high 015 - counting input (DI 7) low
020 - digital filter. (DI 0) /* 0 - disable, 1 - enable 021 - digital filter. (DI 1) … 027 - digital filter. (DI 7)
030 - power-ups counter 031 - uptime in seconds (high) 032 - uptime in seconds (low)
Input Registers: 0 - 1-Wire temperature 1 (-100° - sensor failed or not connected) 1 - 1-Wire temperature 2 2 - 1-Wire temperature 3 … … 31 - 1-Wire temperature 31
033 - number of 1-Wire sensors on the bus, writing '0' - resets sensors enumeration tree and makes new enumaration, old sensors will be deleted, writing any number but '0' - leaves old enumaration tree and appends new sensors to the end
