计数功能概述：

计数是指对事件进行记录和统计，工艺模块的计数器 捕获编码器信号和脉冲，并对其进行相应的评估。可以使用编码器或脉冲信号或通过用户程序指定计数的方向。也可以通过数字量输入控制计数过程。模块内置的比 较值功能可在定义的计数值处准确切换数字量输出（不受用户程序及 CPU 扫描周期的影响）。

在计数器特性里面可以配置计数器的起始值，上下极限值和计数值到达极限时的状态，以及门启动时计数值的状态。在本例中设置起始值为0，上下极限为+/-10000，设置当计数值到达极限时计数器将停止，并且将计数值重置为起始值，将门功能设置为继续计数（图11）。

. TDC IE communication introduction

TDC system is the newest digital control system of SIMADYN D family and it has the highest quality in the SIMATIC control system family.

As one part of TIA family it has powerful communication function. The system provides the MPI communication protocol, Profibus communication protocol, Ethernet communication protocol. It is easy to communicate with other simatic product, for example S7-300, S7-400, HMI and drives product.

For Ethernet communication, the hardware platform is CP51M1 which supply a standard RJ45 Ethernet interface; the old interface CP5100 is discontinued as per Aug. 1 2005.

For communication task, system can exchange process data with other TDC system or PLC S7 system through CP51M1 module.

For communication protocol, TDC system supplies TCP/IP protocol and/or UDP protocol.

For transfer modes, refresh mode, handshake mode, multiple mode and select mode are available for selection.

For net speed it can work with 10Mbit and 100Mbit network, the module can automatically sense the net speed.

2. TDC configuration steps

2.1 Hardware configuration in SIMATIC Manager

2.1.1 Create a new S7 project

2.1.2 Insert a TDC station

2.1.3 Select hardware configuration in SIMATIC Manager, double click to open it

2.1.4 Insert the subrack, CPU, communication board CP51M1 and other module from the hardware catalog
Keep the same type with which is used in the sub rack.

2.1.5 Define the CPU module and communication module properties

For CP51M1, we need to define the module name firstly

For Ethernet property we need to define the IP address and subnet mask

2.1.6 Save and compiled the hardware configuration

2.2 CFC programming

2.2.1 Insert a CFC program in SIMATIC Manager, double click it to open it

2.2.2 Insert the TCPIP communication block into the chart, define the connection address which is set in the hardware configuration and select the proper cycle time

2.2.3 Insert the send function block CTV_P, define the connection:

2.2.4 Insert the DWR_D block to write the communication content to the communication buffer

Here we can define the offset in the communication buffer by set connector1/2. The final result is the sum of offset1 and offset2.

For connector SWP we set it to 1 if it communicates with a PLC.

The data we try to send is set in connector X, here is 44 as an example.

For receive part, we can do it in the same way.

For connector AR of CRV_P, we do not need to define the partner IP address–partner port number.

2.2.5 Compiled the program and download it to the memory card and restart the system

3. S7-400 configuration steps

3.1 S7 hardware configuration

First insert the S7-400 station, and then open the hardware configuration to insert the modules which are available on the sub rack.

For CP443-1 module we need to define the IP address and subnet mask.
The IP address will be used in the CFC program.

3.2 network configuration in the Netpro software
Open Netpro under hardware configuration menu

Select the CPU in the SIMATIC station and insert a new connection,
Select unspecified station and
TCP connection, press apply button.

Select the ID number, record the address LADDR.
Both of them will be used in the S7 program.

Under address menu we need to set the local port number, partner address and port number, press OK button to confirm the setting.

For other connection you need, you can do it in the same way.

Then we need to save and compile the configuration.

We need to download not only the hardware configuration, but also the Netpro configuration to the CPU.

3.3 Programming in the S7 CPU

For the industrial Ethernet communication we use the FC5 AG_SEND, FC6 AG_RECV block.

These blocks transfer and receive the data on the configured TCP connection to and from the Ethernet CP.

Here we made two FC separately for send and receive function, one is FC 30 for FC5, and another is FC31 for FC6.

For FC5, we need to define:

For error evaluate we can check the connector Error and Status. For the status code we can get detail information in the FC5 description documentation.

For FC6, we can do it in the same way.

Because we use DB30 and DB31 in the program FC30 and FC 31, we must insert these two data block and download it to the CPU.

4. Physical connection

TDC side: CP51M1 supply RJ45 interface

S7 side: CP443-1 supply RJ45 interface

Between the double sides we need a Switch to connect.
