SIMATIC 505–2557 Installation and Operation Guide
The SIMATIC 505–2557 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).
