Using OMRON Temperature Input Terminals for Maintenance
Slaves internally convert
display values to
temperature input
values so the Controller
program no longer has
to be modified to
perform this task.
The operating time of a preset temperature range is counted in 1-s units.
The peaks or valleys of temperature inputs that change in a regular pattern
are counted to predict when devices operating with severe temperature
swings are due for maintenance.

Complies with the Highest Safety Standards in the World
The CIP Safety on DeviceNet System conforms to IEC 61508 SIL3 for
functional safety, and EN 954-1 Safety Category 4 for machine safety,
complying with the world's highest level of safety standards.
IEC 61508 SIL 3
Safety circuits must be able to function
to provide safety at anytime. Conversely,
the degree of lack of safety is used as
the indicator. In IEC 61508, safety is
defined as the Probability of Failure per
Hour, or PFH. Based on this, the SIL
(Safety Level) is classified into four
levels. SIL 3 indicates a probability of
dangerous failure of once in 1,000
years, which is the highest level in
machine safety.
EN 954-1 Safety Category 4
EN standards evaluate the level of machine risk and require the
incorporation of risk minimization measures. In EN 954-1, five safety
categories have been established, with Safety Category 4 indicating
designs that require the highest safety design level. This category is
demanded for machines with the highest level of danger, wherein "serious
injury (severed limbs, death, etc.) will occur frequently, with little chance of
escaping danger." This category demands
that a single fault (failure) in any part of
the machine, or a series of faults,
will not lead to loss of the machine's
safety functions.
