DIP Switches Configuration
The EM231 TC modules provide a convenient, isolated interface to seven thermocouple types: J, K, E, N, S, T, and R, which also allow the CTS7-200 PLC to connect low level analog signals of 80mV range. You should use the DIP switched to select the thermocouple type, open wire check, temperature scale, cold junction compensation and burnout direction. All thermocouples connect to a module must be of the same type.
The configuration DIP switches are located on the right bottom of the modules, as shown in the figure 1 and Figure 2, the EM231 4TC module has a 8-pin switches and the EM231 8TC module has a 6-pin switches.
For the DIP switch settings to take effect, you need to power cycle the PLC or the 24V power supply.

Figure 2 EM231 8AI×TCSelecting the thermocouple type by setting DIP switch 1 to switch 8 as shown in Table 1 and Table 2 for the EM231 4TC Module, and Selecting the thermocouple type by setting DIP switch 1 to switch 6 as shown in Table 1 and Table 2 for the EM231 8TC Module.
For the EM231 4TC Module, DIP switch 4 is not used, it should be set to the off position. For the EM231 8TC Module, the open wire check is always enable.

The EM231 8AI×TC module has different beginning input address in different slot and its address is not in AIW but in VW, you can calculate the address by the following formula,
x(VWx) = a × 64 + b × 2 (a is the slot no., and b is the point no.)
