BECKHOFF CP9030 - Manual (Page 19)

Technical Data CP9030
LED1..256
Output for LEDs; "1" = LED on
Up to 256 LEDs can be controlled
BUTTON1..256
Inputs for buttons; "1" = button pressed
Up to 256 buttons can be read
No. of pd outp. words (number of process data output words)
A reference value with which the output status derived from the Control
Panel (CP2020 pd outp.words) is compared. If they differ, then for reasons
of safety no outputs are set.
No. of pd inp. words (number of process data input words)
A reference value with which the input status derived from the Control Panel
(CP2020 pd inp.words) is compared. If they differ, then for reasons of
safety no outputs are set. Inputs can continue to be read.
Pd cycles (process data cycles)
A continuously incremented 8-bit counter. If it is active, Pd errors remains
unchanged.
Pd errors (process data errors)
An error counter that is incremented whenever errors occur in transmission
protocols.
CP2020 Pd outp. words (process data output words)
Returns the size (in words) of the process data output status determined by
the Control Panel.
CP2020 Pd inp. words (process data input words)
Returns the size (in words) of the process data input status determined by
the Control Panel.
