5.5.2 Analog I/O modules
Analog input modules
The analog input modules are available (see also manual ‘Input/Output
modules for CL150, B~IO’):
4AI_UI
4AI_UIT
Each of these modules has 4 analog input channels with 2 bytes data
each. It can be set either on voltage measurement or on current measu-
rement. The setting applies to all 4 channels in the same way.
The measuring ranges can be adjusted via DIP switches (e.g
±
10 volts).
A detailed description of the setting possibilities are to be found in the
documentation of the corresponding modules.
The data size of the 2 byte measuring values can be set on Straight Bi-
nary or 2-complement representation. Additionally, it is possible to
choose between flush left and flush right representation in the 2 byte
word in the input modules ‘4AI_UI’, since the resolution in this modules is
12 bits (including signs).
The input modules ‘4AI_UIT’ has a resolution of 14 bits (including signs)
with flush left representation in the 2 byte word.
. To make during the operation the handling of several different I/O
modules, it is recommended to set all data sizes of all modules on
flush left representation.
The data sizes set by means of the hardware must be adjusted in the
rho4 in the machine parameter P407 (‘Assignment of analog inputs’,
subparameter ‘Format’ and ‘Nominal value’). See page 5−22, Assign-
ment of the analog input channels.
Analog output modules
The analog output modules are available with 4 output channels at 2 by-
tes each (see also Manual ‘Input/Output modules for CL150, B~IO’):
4AO_I
4AO_U
The current and voltage output ranges can be set via DIP switches (e. g.
0 to 20 mA for current output modules and
±
10 volts for voltage output
modules). Detailed description of the setting possibilities, see documen-
tation of the corresponding modules.
The data size of the 2 byte measuring values is defined for the current
output modules on Straight Binary with a resolution of 16 bits.
