Analogue variable inputs 1 to 16 – Analogue values received from the corresponding channel of
the selected output board in the sending system. The values are 32 bit and will assume either a 32
bit signed integer format or 32 bit real format depending on the variable to which it is connected.
Both the specific input channel and its corresponding output channel must be connected to the
same variable type. Different channels on a rack can use different variable types.
The 128 input peer board supports 128 analogue inputs instead of 16 but is otherwise identical.
Note that safety related data using 128 analogue channel blocks must be sent via two different
input/output block pairs and compared at the receiving input end in the application to ensure safety
integrity. Alternatively it may be broken into 16 channel blocks.
