DR 34 ASCII weight display
8.30.1
DR 34 provides an ASCII string with 16 characters, that can be used as a weight display.
The string contains both the current gross/net weight after rounding according to DR 3 as
well as the weight unit. In addition additional parameters and weight values can be
(temporarily) displayed or hidden via a command.
For applications requiring official calibration, DR 34 cannot be used as a main display. In this
case, the "SecureDisplay" software must be used in order to represent the weight and
additional information in a calibratable manner.
The corresponding registers are always currently available at the Modbus end. For operation
with a SIMATIC CPU, DR 34 must be read or requested by WP251 via a command.
