I/Os

For connection to the SINUMERIK 840Di, the following components are offered as

I/Os:

•
the distributed I/O system SIMATIC ET 200
•
the I/O module PP 72/48
The distributed I/O system SIMATIC ET 200
From the range of devices of the distributed I/O system SIMATIC ET 200, all I/O
devices can be used which support a data transfer rate of 12MBaud to be set with
the SINUMERIK 840Di at PROFIBUS DP. These are currently the following I/O de-
vices:
•
ET 200M
•
ET 200B
•
ET 200X
•
ET 200S
As an example for the SIMATIC I/O devices mentioned above, the I/O device ET
200M will be introduced here in brief.
ET 200M
The ET 200M is a modular I/O device designed
acc. to the degree of protection IP 20. It consists
of:
•
a PROFIBUS DP interface module IM 153
•
I/O modules
•
a power supply (from case to case).
The I/O device ET 200M can be extended with a maximum number of 8 I/O mod-
ules of the S7-300 automation system. No slot rules apply for the extension. The
I/O modules can be combined as desired.
The following module types are offered:
•
Standard signal modules of the S7-300 design technology (with module diag-
nosis)
•
Diagnosable instrumentation and control I/O modules (with channel and mod-
ule diagnosis)
•
Redundant modules (with channel and module diagnosis)
•
Ex input/output modules for the coupling of signals from the Ex area (with
channel and module diagnosis)
