10.6 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 2.4, page 2-62).
– PP 72/48
The I/O module PP 72/48 has 72 digital inputs and 48 digital outputs
(Section 2.12, page 2-93).
– 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 module
(Section 2.13, page 2-105).
– SIMATIC S7: ET200 modules
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.
Analog I/O modules
– SIMATIC S7: ET200 modules
See above.
Notice
The digital and analog input/outputs connected on PROFIBUS DP are provided
for both NC and PLC.
It is the sole responsibility of the user to avoid access conflicts:
 On the side of the NC: Parts program/synchronized action
 On the side of the PLC: PLC user program.
