There are 4 digital inputs/outputs in each MCI board extension module (option) (Section
"MCI board extension slot variant" (Page 56)).
The I/O module PP 72/48 has 72 digital inputs and 48 digital outputs (Section "Device
Module PP72/48" (Page 91)).
The ADI4 has two digital input and output bytes that are used for ADI4-internal functions
and as I/O signals at the interfaces of the module (Chapter "ADI4 (Analog Drive Interface
for 4 Axes)" (Page 104)).
Via the PROFIBUS DP, it is possible to connect all subtypes of SIMATIC-S7 I/O modules
of type ET200 (e.g. ET200M) as long as they support a data transmission rate of 12
Mbaud.
See above.
NOTICE
The digital and analog inputs/outputs connected via the PROFIBUS DP are equally
available to both the NC and PLC.
It is the sole responsibility of the user to avoid access conflicts:
• NC side: Part program/synchronized action
• On the PLC side: PLC user program
