11.7 Digital and analog I/O devices
The following digital and analog signal modules are available:
Digital I/O modules
– MCI board extension module (option)
On the MCI board extension module (option) there are 4 digital inputs/
outputs (Section 2.3, Page 2-53).
– PP 72/48
The I/O module PP 72/48 has 72 digital inputs and 48 digital outputs
(Section 2.11, Page 2-79).
– ADI4
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 mod-
ule (Section 2.12, Page 2-91).
– SIMATIC S7: ET200 modules
Via the PROFIBUS DP it is possible to connect all subtypes of SIMAT-
IC–S7 I/O modules of type ET200 (e.g. ET200M) as long as they support
a data transmission rate of 12 Mbaud.
Analog I/O modules
– SIMATIC S7: ET200 modules
See above.
Notice
The digital and analog input/outputs connected via the PROFIBUS DP are
equally available to both the NCK and PLC.
It is the sole responsibility of the user to avoid access conflicts:
S On the NCK side: Part program/synchronized action
S On the PLC side: PLC user program
