Status display The PCS 830 features a 7-segment STATUS display which informs about
the state of the board! The following display states are currently possible:
„0“: programmable controller is set to „STOP“, i.e. the PCS 830 waits
for the „RUN“ signal.
„1“: The PCS 830 waits for the complete reception of the cross-
reference list.
„7“: TIMEOUT fault, i.e. the communication between PCS 830 and PCS
was either interrupted (PCS shows „TIMEOUT“ -> cable break) or
the PCS has twice received (one after another) wrong data (PCS
shows „CONNECT“). In case of the „CONNECT“ fault, noise
suppression measures are to be explored and/or to be improved if
necessary.
„8“: CONNECT fault, i.e. the PCS 830 has twice received (one after
another) wrong data (PCS shows „TIMEOUT“). In this case, noise
suppression measures are to be explored and/or to be improved if
necessary.
„9“: WATCHDOG fault, i.e. the PCS 830 board is either located in an
very noisy environment or the PCS 830 is defective (communi-
cations cannot be started anymore).
„-“: The PCS 830 has either sent or received a repeat request. With a
reparable fault, the „-“ extinguishes subsequently again. If the fault
was not reparable, a „7“( TIMEOUT) or „8“( CONNECT) is
subsequently displayed.
„.“: This point lights as so soon as the PCS 830 has received a tested
package and is thus ready for the data interchange with the
programmable controller. With an increasing data throughput this
point will be dimmed. This can be influenced by specifying the ZV,
S,... parameter for the serial programming of the PCS.
