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.

DIP switch configuration
The EM231 module provides a convenient and isolated interface for the seven thermocouple types: J, K, E, N, S, T, and R. It also allows to connect tiny analog signals (±80mV). All thermocouples connected to the modules must be the same type, and it is best to use a shielded thermocouple sensor.
Thermocouple modules use DIP switch to select the thermocouple type, disconnect check, measurement unit, cold end compensation and open fault direction.
For the EM231 4TC module, SW1 ~ SW3 is used to select the thermocouple type, SW4 is not used (set to the OFF position), SW5 is used to select the direction of wire breaking detection, SW6 is used to select whether to conduct wire breaking detection, SW7 is used to select the measuring unit, and SW8 is used to select whether to conduct cold end compensation.
For the EM231 8TC module, SW1 ~ SW3 is used to select the thermocouple type, SW4 is used to select the direction of wire breaking detection, SW5 is used to select the measuring unit, SW6 is used to select whether to conduct cold end compensation. wire breaking detection is fixed to be yes, no need to set.
In order for the DIP switch setting to work, you need to Power off then on for the PLC or the 24VDC.

Software Configuration(231-7PF32)
For EM231 8AI×16 bits, reading in VW instead of AIW. The relative location of the module is different, so is the corresponding address. Calculation formula:
x(VWx) = slot no. × 64 + input channel × 2
The slot number of the address quick reference table corresponds to the installation location of the module. The first expansion module close to the CPU has the slot number of 0, the second expansion module has the slot number of 1, and so on. There are 8 input channels, from A to G, and the corresponding number is 0 to 7.
 Quick reference of address based on formula above:
