Baud rateSelect baud rate for your device (9600 / 19200 / 38400 bps)
Set number of stop bits
Set parity (None, Odd, Even)
Maximal length of data that can be
read by one request in bytes
Enables optimization, i.e.
reading of neighbouring
registers in one request
Maximum number of registers that can
be read by one request
I-CB sets communication
drop out alarm after it doesn’t receive answer within this
timeout
Not to be changed by user
Request delay – after this time next request is issued
after receiving previous answer
Not to be changed by user

Reading procedure
Wait for Refresh
period of any register
Read that register
Period time – no reading

Analog inputs
Factor multiplies the read numberRegister Name is
shown in ICBEdit
Device Addr. is address of Modbus
device
Modbus register address (e.g. 4xxxx for holding registers)
Length of value in registers (i.e. 2 for a
4-byte value)
Value type – signed/unsigned and
byte length
Offset is added to the value read from Modbus device after
it was multiplied by factor
Period of request sent from I-CB to Modbus device

Binary inputs
Length of value in registers (1 for binary inputs)
Mask selects bit(s)Value is then compared to selected bits and if they
match the binary input to the controller is activated
Error mask selects error bit(s)
Error Value says which values means that the
binary signal is not valid

Binary inputs
ExampleRegister read from the device:0000 0010 0110 1100
Mask = $0040 (0000 0000 0000 0100)Value = $0040 (0000 0000 0000 0100)
0000 0010 0110 1100 read registerAND
