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.

You can wire the RTD sensors directly to the EM231 RTD modules, or you can use extension wires. Please use shielded wires to acquire best noise immunity. If you use shielded wires, connect the shield to the ground on pin 1 to 4 of the signal connector. This ground is the same ground as is present on the power connector pin 3 to 7. If you do not use an RTD input channel, you should wire a resistor to the unused channel inputs in order to prevent errors from floating inputs from blocking error indications from valid channels.
Connect user power to the power connector pin 1 and 2. You must connect pin 3 to a nearby chassis ground (Figure 2).
You can wire the RTD module to the sensor in three ways (shown in Figure 3). The most accurate mode is 4 wire (see Figure 3). The least accurate mode is 2 wire, which is only recommended if errors due to wiring can be ignored in your application.
Figure 1 Connector Terminal Identification for RTD Modules
Configuration
The EM231 RTD modules provide a convenient interface to connect CTS7-200 PLC to several different RTDs. It also allows the CTS7-200 PLC to measure three different resistance ranges. You must use DIP switches to select RTD type, wiring configuration, temperature scale, and burnout direction. Both RTDs connect to a module must be of the same type.
The configuration DIP switches are located on the right bottom of the module, as shown in Figure 4. For the DIP switch settings to take effect, you need to power cycle the PLC or the 24V power supply.
Selecting the RTD type
Select RTD type by setting DIP switch 1 to switch 8 to correspond to the RTD as shown in Table 1 and Table 2.
