This function is valid for the present AD module, it is invalid for other AD modules
expanded by couplers.
Measuring range switch configuration
Function
description
This function is used to switch the range of the input channel of the AD
module (or the output channel of the DA module). Both modules default to
the range of 0~10V.
The range corresponds to the type number of the expansion submodule,
please refer to the table below.
Model
AD module (ZMIO300-4AD)
DA module (ZMIO300-4DA)
Data dictionary
5000h + expansion NO. of relative AD module (or DA module)
Example
′The first expanded expand submodule is AD module, the second is DA
module.
SDO_WRITE (0,0, $5001,1,6,3) ′AD module is switched into -10 ~
10V measuring range
SDO_WRITE (0,0, $5001,1,6,5) ′AD module is switched into 0-
20mA measuring range
SDO_WRITE (0,0, $5002,1,6,11) ′DA module is switched into -10 ~
10V measuring range
SDO_WRITE (0,0, $5002,1,6,13) ′DA module is switched into 0-20mA
