With CfgPlcFastInput, you define the PLC inputs that are interrogated within
the position controller cycle time (see "MP_ipoCycle" on page 1481) instead of
within the defined PLC cycle time (see "MP_plcCount" on page 1481). In
MP_number, enter the PLC input of the control that is to be used as a fast PLC
input. You define the associated symbolic PLC operands set by the fast PLC
input in MP_operand.
A maximum of five PLC inputs can be defined as fast PLC inputs. For this
purpose, five input arrays [arrays 0...4] are available in the configuration editor
of the control.
For the control to identify with certainty a signal change, the signal duration at
the fast PLC input must last a minimum of 4 ms.
Warning
Only the PLC inputs of the control can be defined as fast PLC inputs, and
not the inputs on a PL 510.
