Our Advantages

CTSC-200 series is a new generation of high-performance PLC with high cost-effective,excellent performance,multi-protocol communication ports and a abundant instruction,which can apply to various of industries and adapt to the complex control requirements of small and medium control system.

Powerful communication capability

Ethernet communication mode:10/100Mbps Ethernet support MODBUS_TCP and UDP_PP protocol.Multiple host networking communication in the LAN, to programming, debugging and remote monitoring in the WAN.

PPI communication mode:CTSC-200 series CPU integrated 1-2 PPI port which hardware interface is the RS485 or RS232,provide communication rate 9.6Kbps,19.2Kbps,187.5Kbps,PPI is token-ring network structure,can form PPI network without relay,to complete data exchange through NETR and NETW,each exchange package can be up to 200bytes,each CPU can connect eight modules,that is each CPU can connect to 8 PC or other CPU.

If the I/O of some system is relatively too large that one CPU can not meet requirement,can achieve by several CPU,multi-CPU structure can achieve distributed control thant with high sstem reliability.The data exchange is extremely fast and convenient because of the powerful communication capability among different CPUs.

MPI communication mode:CTSC-200 series CPU can connect to the MPI network,communication rate 19.2Kbps,187.5Kbps which only work as slave station in the MPI network.The different slave stations can not communication each other while the master stations can read the data of slave station.

Profibus-Dp or Ethernet communication mode:CPU can be connected to the Profibus field by by DP slave stations,as salve station of certain master station,it can exchange data fast and real-time also can run independently which with high reliability.

CPU can be connected with industrial Ethernet by Ethernet module which is suitable for building control or other applications with several stations.

CANopen communication mode:To form network through CAN communication,each CAN master station can connect 32 CAN slave stations or devices,baud rate up to 1MBit/s within 25m,baud rate up to 20MBit/s within 2500m.

Freeport communication mode:CPUs provide 1-2 freeport,embedded several free communication protocol library such as Modbus,USS etc.

CPU 226L,CPU226H with two freeport can communicate simultaneously so as to meet the requirements of such occasions like high-speed communication ,synchronous control,many peripherals.

Calibration and the position of range switch
Input calibration
Because the calibration adjustment affects the OPAMP behind the analog multiplexer, it affects all user input channels.In addition, because the component parameters of the input channels in front of the multiplexer may differ, there is a slight difference of the same input signal on different channels even after calibration.
The input has been filtered in the module, so the measurements is stable. Start the analog input filter for all input of the module for better performance parameters. When calculating the average value, select the sampling times above 64.
Calibration steps:
1) Cut off external power of modules, configure DIP switch to select needed range.
2) Connect CPU with module power, wait for 15min above.
3) Use a transmitter, a voltage input source or a current input source to add the zero signal to module input.
4) Read measurement of the input in CPU.
5) Adjust GAIN potentiometer till the reading is 32000.
Range selection
The following table shows how to set the range of EM231 4AI with DIP switch. Use 1, 2and 3 to select the analogy input range which can be set to the same.
Attention: the unused DIP switch SW4 ~ SW6 must be set to OFF.
