Analog modules
5.8 Assigning parameters to analog modules
Parameters
● Measuring range
● Reference temperature
● Temperature unit
● Temperature coefficient
for temperature
measurement with
thermal resistance (RTD)
● Interference frequency
suppression
● Smoothing
● Reference junction
If you use the module in ER-1/ER-2, you must set this parameter to "No" because the interrupt lines are not available in
1
ER-1/ER-2.
Only in the CR (central rack) is it possible to start up the analog modules with the default settings.
