7.8.3 Analog inputs
Transferring the
analog inputs of the
MC
±10 V– analog inputs and inputs for Pt 100 thermistors are available either on
the MC unit or on the external PL (see Chapter 3, Mounting and Electrical
Installation). Use Module 9003 to load the current temperatures of the Pt 100
thermistors or the values of the analog inputs.
To transfer the analog inputs and temperature inputs of the external PL, use
Module 9138.
Module 9003 Transfer the analog input of the MC
This module reads the current value of the specified analog input, regardless
of whether it is actually connected.
Value range ±10 V input: –10 V to +10 V, at a resolution of 10 mV
Value range Pt 100 input:0 to 100 °C, at a resolution of 0.1 °C
The module can be called only in the cyclic PLC program.
