  • Configuration

Table 1 shows how to configure the EM 231 module using the configuration DIP switches. Switches 1, 2, and 3 select the analog input range. All inputs are set to the same analog input range. In this table, ON is closed, and OFF is open. (SW4 to SW6 should be set to the OFF position)

  • Software Configuration

  • The EM231 8AI 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.)

    Note:  Because the offset address of Td2X text display is also in VW0, so If you need to use Td2X text display in your system, please don’t put the EM231 8AI×TC module in slot 0, or the td2X will not work normally. SIEMENS TD200 text displayer is same as TD2X.(SIEMENS is the trademark of SIEMENS AG.)
