Certification, CE label and other standards

Service and support

The S7-200 SMART series is a line of micro-programmable logic controllers (Micro PLCs) that can control a variety of automation applications. Compact design, low cost, and a powerful instruction set make the S7-200 SMART a perfect solution for controlling small applications. The wide variety of S7-200 SMART models and the Windows-based programming tool give you the flexibility you need to solve your automation problems.

This manual provides information about installing and programming the S7-200 SMART CPUs and is designed for engineers, programmers, installers, and electricians who have a general knowledge of programmable logic controllers.

To understand this manual, it is necessary to have a general knowledge of automation and programmable logic controllers.

This manual describes the following products:

● STEP 7-Micro/WIN SMART V2.3

● S7-200 SMART CPU firmware release V2.3

For a complete list of the S7-200 SMART products and article numbers described in this manual, see Technical Specifications (Page 679).

Refer to the technical specifications for more information.

In addition to our documentation, we offer our technical expertise on the Internet on the customer support web site (http://www.siemens.com/automation/).

Contact your Siemens distributor or sales office for assistance in answering any technical questions, for training, or for ordering S7 products. Because your sales representatives are technically trained and have the most specific knowledge about your operations, process and industry, as well as about the individual Siemens products that you are using, they can provide the fastest and most efficient answers to any problems you might encounter.

Preface

Security information

Siemens provides products and solutions with industrial security functions that support the secure operation of plants, systems, machines and networks.

In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens’ products and solutions only form one element of such a concept.

Customer is responsible to prevent unauthorized access to its plants, systems, machines and networks. Systems, machines and components should only be connected to the enterprise network or the internet if and to the extent necessary and with appropriate security measures (e.g. use of firewalls and network segmentation) in place.

Additionally, Siemens’ guidance on appropriate security measures should be taken into account. For more information about industrial security, please visit (http://www.siemens.com/industrialsecurity).

Siemens’ products and solutions undergo continuous development to make them more secure. Siemens strongly recommends to apply product updates as soon as available and to always use the latest product versions. Use of product versions that are no longer supported, and failure to apply latest updates may increase customer’s exposure to cyber threats.

To stay informed about product updates, subscribe to the Siemens Industrial Security RSS Feed under (http://www.siemens.com/industrialsecurity).

1.2 New features

STEP 7-Micro/WIN SMART V2.3 and the S7-200 SMART V2.3 CPUs introduce the following new features:

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)

-200 SMART CPU firmware release V2.3 does not apply to the CPU CR40 and CPU

All CPU models now blink the STOP LED at 1 Hz if a value is forced (in RUN or STOP mode).

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.

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

1.3 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.

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

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.

1.3 CPU feature differences

The CRs models provide the RS485 port as the only programming port for the CPU. Using STEP 7-Micro/WIN SMART and a USB-PPI cable, you can perform the following tasks:

● Upload and download your program

● Monitor program functions

● Perform firmware updates

If you use Freeport (Page 465) in your program, attaching a USB-PPI cable forces the CPU to exit Freeport mode and enables PPI mode. PPI mode allows STEP 7-Micro/WIN SMART to regain control of the CPU.

Since the CRs CPU models support only an RS485 programming port, the CPU always reserves one connection for the STEP 7-Micro/WIN SMART programmer connection. The CRs model CPUs still support four connections on the RS485 port for HMIs.

You cannot use the CPU instructions that utilize the Ethernet port on the CRs models. The instructions that are not available in the CRs models are as follows:

SET SET Write data through the Ethernet

TRECV TRECV Receive OUC data through the Ether-

TDCON TDCON Disconnect an OUC Ethernet connec-

The CRs models do not have a real-time clock; however, the CRs models still support time instructions. The time resets to the default time (January 1, 2000) on every power cycle. The CPU maintains time with limited accuracy without the real-time clock.

Because the CRs models do not support a microSD card, you use the Reset to factory defaults command (Page 164) using the RS485 port in case you forget your password.
