CPU feature differences
The S7-200 SMART V2.3 CPU family includes twelve CPU models, separated into two lines:
the Compact Line and the Standard Line. The first letter of the CPU designator indicates a
line, either Compact (C) or Standard (S). The second letter of the designator indicates AC
power supply / relay outputs (R) or DC power supply / DC transistor (T). The number in the
designator indicates the total onboard digital I/O count. The new compact models are
designated by a lower case "s" character (serial port only) following the I/O count.
CRs models
The CPU CR20s, CPU CR30s, CPU CR40s, and CPU CR60s models have the following
differences from the standard CPUs:
●
No Ethernet port: The RS485 port is now the programming port.
●
STEP 7-Micro/WIN SMART uses a USB-PPI cable to program the CPU through the
RS485 port.
●
The CPUs reserve one connection for the STEP 7-Micro/WIN SMART programmer
connection.
●
No CPU instructions that require an Ethernet port
●
No support for data logs
●
No real-time clock
●
No microSD card reader
●
No signal board support
●
No signal module support
●
No 24 V DC sensor supply
●
No motion control
●
Support for only PROFIBUS/RS485-capable HMIs
●
12 KB of ladder memory and 8 KB of V memory
●
Retentive memory limited to 2 KB
No Ethernet port
Because the CRs models have no Ethernet port, the RS485 port is the programming port.
STEP 7-Micro/WIN SMART uses the USB-PPI cable to program the CPU. You can now
program any CPU over all serial ports, including the PROFIBUS DP01 modules.
