6.15.1 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.
Input addresses
Addresses applicable to the inputs:
Channel Address
0 Module start address
1 Module start address + 2 bytes address offset
2 Module start address + 4 bytes address offset
3 Module start address + 6 bytes address offset
