6.11 Parametrization of the Analog Input (AI) and Digital
Input (DI) blocks
Analog measuring values are transmitted to a PLC by the Analog Input Blocks (AI).
Digital measuring values are transmitted to a PLC by the Digital Input Blocks (DI).
The Prosonic S FMU90 provides 10 AI Blocks and 10 DI Blocks.
These blocks are parametrized in the "Outut/calculations" menu.
The parameters of this menu are described in the following sections.
6.11.1 "digital input" (DI)
output/calculat. 01000
analog input
digital input
Profibus DP
"output calculations"
output/calculat. 0XB01
digital input 1
digital input 2
digital input 3
digital input 4
Use this list to select the DI block you are going to configure.
"digital input N" (N = 1 - 10)
digital input 1 O1B03
allocation:
value:
status:
"allocation"
Use this parameter to select a switching state. Occurrence of this state will be indicated by the DI
block.
Selection
• relay
The DI block is connected to one of the relays of the instrument. After selection of this option,
the "relay" function appears, where you can select one of the relays.
• pump control N (N = 1 or 2)
is only available if a pump control has been configured. After selection of this option, an additional
selection list appears which is used to allocate the DI block to one of the pump relays.
• rake control
is only available if a rake control has been configured. After selection of this option, an additional
selection list appears, which is used to allocate the DI block to the rake control relay.
• none
No value is transferred via the DI block.
