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.

DIP switch configuration
EM231 thermocouple modules supports J/K thermocouple. The module provides a 6-bit DIP switch for selecting measurement unit, cold end compensation and open circuit fault direction. As for whether to conduct wire breaking detection, EM231 thermocouple forces the wire breaking detection just as the EM231 8TC.
The 6-bit DIP switch is located below the module, as shown in the figure below. SW1 ~ SW2 was not used, use SW3 to select the thermocouple type, use SW4 to select the direction of wire breakage detection, use SW5 to select the measuring unit, and use SW6 to select whether to conduct cold end compensation. Power off the PLC power supply and then power on to make the DIP switch setting work.
| Setting items | Switch position | Setting |
| Select thermocouple | SW3 | 0: J type 1: K type |
| Direction of broken line detection | SW4 | 0: positive(+3276.7°) 1: negative(-3276.8°) |
| Measuring unit | SW5 | 0: ºC 1: ºF |
| CJC | SW6 | 0: yes 1: no |
