SP-COP Safety controller consisting of a controller module of the samosPRO
COMPACT product family, as well as optionally connectable expan-
sion gateways and I/O modules.

PLC Programmable Logic Controller
Stuck-at high Stuck-at high is an error in which the input or output signal gets
stuck at On. The causes for a Stuck-at high can be short-circuits to
other input and output lines, often called cross-references, or defec-
tive switching elements. Stuck-at high errors are discovered
through plausibility tests, such as sequence errors in two-channel
input circuits or using test pulses in input and output circuits.
Stuck-at low Stuck-at low is an error in which the input or output signal gets
stuck at Off. The causes of a stuck-at low can be line interruptions
in input circuits or defect switching elements. Stuck-at low errors
are discovered through plausibility tests and usually do not require
immediate error recognition.
TCP Transmission Control Protocol, Internet standard protocol for the
transport layer specified in RFC 793
Test pulses or scan
gaps
Test pulses or scan gaps are brief switch-
offs / interruptions in input
and output circuits, which are generated in a targeted manner to
detect stuck-at high errors quickly. Test pulses check the switch-off
ability of switching elements during operation on an almost conti-
Test pulse error Test pulse errors are undetected test pulses, which lead to a negati-
ve test result and thus switch-off of the affected safety circuits.
