Publication 1753-IN011A-EN-P - October 2005
Surge on Digital Inputs
An EN 61000-4.5 surge impulse can be read as a short duration HI signal. To avoid
an error:
• install shielded input lines to prevent effects of surges in the system, or
• implement software filtering in the user program. A signal must be present
for at least two cycles before it is used by the rest of the logic in the user
program.
Line Control
Line control is a short-circuit and line break monitoring system (for example, E-Stop
inputs) which can be configured for the GuardPLC system.
