Overview
The analog input modules described here break down into
• multi-function modules for current, voltage and temperature
• multi-function modules for current, voltage and temperature
measurements, and
• special, highly accurate modules for current and voltage mea-
surements or temperature measurements.
All modules automatically supply channel-specific and module-
internal diagnostics data, except module 6ES7 331-1KF01-
0AB0. With the latter module, channel failure is identified by the
PCS 7 analog driver block.
The individual channels of the analog input modules can be pa-
The individual channels of the analog input modules can be pa-
rameterized in groups independently of each other.
