Linking in the PLC with 2-bit values
The limit information consists of 2 bits.
Limitn
can be linked to the PLC or a task in the System Man-
ager:
PLC: IEC61131-PLC contains no 2-bit data type that can be linked with this process data directly. In
order to transmit the limit information, therefore, define an input byte, e.g.
Link the limit to an existing variable.
Additional task: 2-bit variables can be created in the System Manager.

Filter mode (FIR and IIR), Index 0x0800:06, 0x0800:15
The EPI31xx, ERI31xx and EPI4xxx, ERI4xxx modules are equipped with a digital filter, which, depending on
the setting, can assume the characteristics of:
• a filter with finite impulse response (
F

R
esponse Filter,
FIR filter
) or
• a filter with infinite impulse response (
