Download 505 Differential Analog Input Module

Output Registers
The PPX:505-2555 module also utilizes 32 WY registers. These registers are
used to transfer the scaling values, the alarm setpoints, the filtering time
constants, and the averaging count values to each of the sixteen channels.
After the data is loaded into the module, these registers then enable each of
the functions on a channel-by-channel basis. These WY registers become
control words for enabling each channel for special operations (Table 3-4).
