Application
The CP 343-2P / CP 343-2 is the AS-Interface master connection
for the SIMATIC S7-300 and the ET 200M.
Through connection to AS-Interface it is possible to access max.
248 DI/248 DO per CP, using 62 A/B slaves with 4DI/4DO each.
With the integrated analog value processing it is easy to transmit
analog signals (per CP up to 62 A/B analog slaves with a maxi-
mum of two channels each or up to 31 A/B analog slaves with a
maximum of 4 channels each).
The CP 343-2P is the further development of the CP 343-2 and
contains its entire functionality. An existing STEP 7 user program
for a CP 343-2 can thus be used without restrictions with a
CP 343-2P. It is only in STEP 7 HW-Config that the two modules
are configured differently, with the CP 343-2P offering additional
options. This is why the CP 343-2P is recommended.
