The gateway implements the function of ID mapping by setting the ID range and the
ID offset. The ID range starts from the slave start ID to the slave end ID. Only
channels with channel type slaves can be mapped, including serial port (RTU Slave or
ASCII Slave) and TCP Slave.
Slave ID mapping formula is as follows:
“Virtual ID + ID Offset = Real ID”
The ranges of the Virtual ID and Real ID in the formula are 1 to 247.
