The process image size of the IO-Link master can be adjusted to the devices
(switches, IO-Link compatible devices, etc.) attached to the IO-Link ports.
Process image sizes of 4, 6, 8, 10, 12, 16, 20 or 24 bytes can be set. As process
data is exchanged, the process image has a fixed structure of a control/status byte,
Mailbox bytes and SIO byte regardless of the current configuration.
After the SIO byte, another data storage area is available in which cyclical process
data can be transferred from IO-Link devices.
