Description

2.4 Number of RFID channels that can be connected

2.4 Number of RFID channels that can be connected
Each reader channel occupies 1 word in the input and output area of a SIMATIC S7. The
maximum number of bus nodes permitted by SIMATIC can always be operated. The
following table provides an overview.

(distributed via ET 200M)
RF170C
(distributed via ET 200pro)
ASM 456
RF180C
5)
The CPU types specified here may not be complete since the range of CPUs and the associated functions are
1)
being continuously expanded.
Central installation can include up to 3 expansion racks. A DP connector is not necessary in this
2)
configuration variant.
In the distributed configuration, up to 8 RFID modules (ASM 475) can be operated in each ET 200M.
3)
In an ET 200pro distributed I/O, up to 9 RF170C can be plugged in.
4)
The number of RF180C communications modules depends on the network and the CPU being used
5)
(number of IO addresses). The system configuration (redundancy) may lead to restrictions. Note the
manuals of the CPUs and the manual "SIMATIC PROFINET system description".
