5.3 Analogue modules
AS-Interface - Analogue modules
Using the new specification 2.1, Profile S7.3 now allows analogue values to
be transmitted just as simply and securely as binary signals without special
programming in the PLC. In max. 35 ms, analogue values for pressure, temperature,
fill levels, or anything, are available to the PLC with 16-bit resolution
via AS-Interface. Analogue output signals have a maximum resolution
of 13 bits. The master automatically detects analogue modules and takes
over data conversion via "plug and play", without needing any configuration.
The field modules are housed in the G4 housings described earlier and are
available in these versions:
Analogue module with 2 inputs for 0 ... 10 V,
Analogue module with 2 outputs for 0 ... 10 V,
Analogue module with 2 inputs for 0/4 ... 20 mA,
Analogue module with 2 outputs for 0/4 ... 20 mA,
Analogue module with 4 outputs for connection of a PT100 sensor
Analogue values are galvanically isolated from the AS-Interface and analogue
modules can be supplied with power from the AS-Interface or externally
(configured by jumper). The modules include a display for bus communication,
external auxiliary power, and the inputs/outputs.
For the switch cabinet there is a universal analogue module with inputs for
current and voltage (switchable) in a KE2 housing.
A module with the same design enables the connection of 4 inputs for
PT100 sensors.
