Product Description:

Further details can be found in volume 2, chapter 5.1 "Generalinformation for the use of analog inputs and outputs".In order to make sure, that unused input channels have adefined 0V level, they may be shorted to AGND. Unused inputs must be configured with "unused". The relationship between the analog input signals and the converted numbers is illustrated in the following figures.The configuration is performed by setting certain bits in the system constants KW 86,00 to KW 86,07 as follows:and if in addition the UP5 terminal is left unconnected,no restrictions exist for the inputs. The input signal voltages then may be within -30 V and +30 V. There is no restriction for the input/output group concerning its safety against reversed polarity

Product's Character:

Resolution in the PLC system:The measured values are converted with a resolution of12 bits, i.e. 11 bits plus sign for voltage and 12 bits without sign for current. The ranges 0...5 V und ±5 V are converted
with 10 bits plus sign.. If the terminals are used as digital inputs, the input signal delay can be configured to 7 ms (default) or to 1 ms. The configuration is performed by setting certain bits in the system constant KW 85,01 as follows: If the terminals are used as digital outputs, the output signals "1" are individually monitored by the re-readable input. If the output status is wrong, an overall error message is generated for the involved output group.The error is displayed by the red LED Ovl. and by errorflags of the PLC then. The error could have been caused by overload, shortcircuit or missing supply voltage UP5/ZP5.The technical specifications are the same as with the
other digital inputs and outputs.
