New features

STEP 7-Micro/WIN SMART V2.3 and the S7-200 SMART V2.3 CPUs introduce the following
new features:
New CPU models
S7-200 SMART has four new compact serial CPU models:
● CPU CR20s AC/DC/Relay (6ES7288-1CR20-0AA1)
● CPU CR30s AC/DC/Relay (6ES7288-1CR30-0AA1)
● CPU CR40s AC/DC/Relay (6ES7288-1CR40-0AA1)
● CPU CR60s AC/DC/Relay (6ES7288-1CR60-0AA1)
Note
CPU CR40 and CPU CR60
S7-200 SMART CPU firmware release V2.3 does not apply to the CPU CR40 and CPU
CR60 models.
Status LED states
All CPU models now blink the STOP LED at 1 Hz if a value is forced (in RUN or STOP
mode).
High Speed Counters (HSC)
New HSC capabilities are as follows:
● The number of HSCs increased from four to six on the SR and ST CPU models. The new
CRs CPUs have four HSCs.
● The SR/ST30 CPUs now utilize the high speed inputs I0.6 and I0.7 for HSC4. This means
that the SR/ST30 CPU has one more 200 kHz counter than the other SR/ST models.
USB/PPI serial interface support by STEP 7-Micro/WIN SMART
You can now use a USB/PPI Multi-Master cable to program all CPU models through any of
the following serial ports:
● RS485 port
● Signal board port
● DP01 PROFIBUS port
