CONV
The CONV parameter is only applicable when the BT function block is used in
conjunction with a SIM 323 module to provide interrogation voltage for contacts
as shown below:
The default setting is low (logic “0”) for no interrogation voltage provided. If no
interrogation voltage is provided the outputs are available to be used separately
from the inputs. The CONV parameter affects two adjacent channels and is set
on the odd (1,3,5,etc.) channel.
Hardware Fault
The status word data block is deleted if a hardware fault is present and the block
is not simulated. The bit ”KG”, channel valid, is reset (with signal TTD if
configured). In the case of simulation, the hardware fault has no effect on the
SIM BT function block.
