Wiring Warnings and Cautions

This section describes the Warnings and Cautions when wiring the IPC Machine Controller.
If external power supplies for slaves or other devices are overloaded or short-circuit-
ed, the voltage will drop, outputs will turn OFF, and the system may be unable to read
inputs. Provide external safety measures in controls with monitoring of external power
supply voltage as required so that the system operates safely in such a case.
Provide safety measures in external circuits to ensure safety in the system if an ab-
normality occurs due to malfunction of the product or due to other external factors af-
fecting operation. Not doing so may result in serious accidents due to incorrect opera-
tion.
Emergency stop circuits, interlock circuit, limit circuits, and similar safety measures
must be provided in external control circuits.
Provide measures in the communications system and user program to ensure safety
in the overall system even if errors or malfunctions occur in data link communications
or remote I/O communications.
Unintended behavior may occur when an error occurs in internal memory of the prod-
uct. As a countermeasure for such problems, external safety measures must be pro-
vided to ensure safe operation of the system.
