SENSORS BASE ADDRESS
Following formulas will show how to get every connected sensor’s base address.
Local Sensors (Analog)
BASE_ANALOG = 0
Channel_ADDRESS = (Channel-1)*16 + BASE_ANALOG
8CH Channel = [1;8]
24CH Channel = [1;24]
Digital Sensors (Smart Modbus)
8CH 24CH
BASE_DIG 128 384
Channel_ADDRESS = (Channel-1)*16 + BASE_DIG
Channel = [1;254]
Multiplexer Sensors
8 CH 24 CH
BASE_MUX 4224 4480
Channel_ADDRESS = ((Address-1)*32*16)+((Channel-1)*16)+BASE_MUX
Address = [1;16], Channel = [1;24]
Digital Inputs
8 CH 24 CH
BASE_DIN 12416 12672
Channel_ADDRESS = ((Channel-1)*16) + BASE_DIN
Channel = [1;2]
Virtual Channels
8 CH 24 CH
BASE_VIRT 12448 12704
Channel_ADDRESS = ((Script-1)*16*16)+((Channel-1)*16)+BASE_VIRT
Script = [1;5], Channel = [1;16]
