Digital Input Modules

The group of digital input I/O modules is divided into 8 types of modules:
Type of module
2DI_2DIA_2ACK
2DI_2DIA_2ACK_PI
Digital input modules receive the consumer status (IOCS) from the I/O
controller and supply it with the provider status (IOPS) of the existing input
and optional existing diagnostic information.
The following table shows a list of the number of bytes for the individual
modules that are allocated in the respective process image (PI) and the
telegrams (TLG) in the direction of transmission and reception (Tx, Rx).
