■ STATUS
Analog input modules (models: R7E-SV4, R7E-TS4, R7E-RS4, R7E-MS4, R7E-CT4E) can show input status of each channel.
Analog output modules (models: R7E-YS2, R7E-YV2) and discrete I/O modules (models: R7E-DA16, R7E-DC16A, R7E-
DC16B) shows '0' at the same address.
15
Burnout, input range error (≤-15%, ≥+115%)
0 : Normal
ADC error (no response from ADC)
0 : Normal
