Operating principle of SM 334; AI 4/AO 2 x 8/8 Bit

Introduction
SM 334; AI 4/AO 2 x 8/8 bit is a non-isolated analog IO module. SM 334; AI 4/AO 2 x 8/8 Bit
is not programmable.
Addressing
The inputs and outputs of the module are addressed beginning at the module start address.
The address of a channel is derived from the module start address and an address offset.
