Intelligent modules
The input data of the intelligent modules occupy 10 registers
(register 0×0000 to 0×0008):
XN-2AI-I(0/4...20MA)
→ 2 registers (0×0000 and 0×0001)
– channel 0: not used, measurement range 0 to 20 mA
register 0×0000: 0×00 0×00
– channel 1: not used, measurement range 0 to 20 mA
register 0×0001: 0×00 0×00
→ The module shows the lower measurement limit when
the channel is not used.
XN-2AI-THERMO-PI
→ 2 registers (0×0002 and 0×0003)
– channel 0: thermo element type K connected.
register 0×0002: 0×00 0×D1
→ The module shows a measured temperature of
0×D1 ≈ 21,0 °C at channel 0.
– channel 1: no thermo element connected
register 0×0003: 0×F5 0×74
→ As the channel is not used, the module shows the
minimum value at channel 1 (- 270 °C).
