PERFORMANCE DATA Performance data given in this manual is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of OMRON's test conditions, and the users must correlate it to actual application requirements.
!WARNING It is extremely important that a PLC and all PLC Units be used for the speci- fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC system to the above mentioned applica- tions.
• The PLC outputs may remain ON or OFF due to deposits on or burning of the output relays, or destruction of the output transistors. As a counter- measure for such problems, external safety measures must be provided to ensure safety in the system.
• Locations subject to possible exposure to radioactivity. • Locations close to power supplies. !Caution The operating environment of the PLC System can have a large effect on the longevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PLC System.

• Be sure to press terminals until they are fully seated. • Mount Units only after checking terminal blocks completely. • Before mounting a wired terminal block to the main block, be sure that the terminal block-main block combination is correct.
EMC Directive OMRON devices that comply with EC Directives also conform to the related EMC standards, so that they can more easily be built in to other devices or the overall machine. The actual products have been checked for conformity to EMC standards.

This function records the total time that the Slice I/O Unit's internal circuit (Power ON Time) Monitor power has been ON. A warning level can be set in the Unit and a warning flag will be turned ON when the set warning time is exceeded. The Power ON Time can be read with an explicit message command or from the Configura- tor.

Slice I/O Terminal Introduction The status can be checked at the Master using the Off-wire Detection Flag. This function is valid only for the input ranges 4 to 20 mA and 1 to 5 V. User Adjustment Input or output values can be adjusted to compensate for errors in the input or output voltage or current resulting from the characteristics or connection methods of the I/O device.

Section 2-2 Unit Numbers and I/O Allocations I/O Allocation I/O data is allocated to the I/O Units in the order that they are connected to the Example Communications Unit, regardless of the I/O Units’ models. Unless special allocation data settings are selected with the Communications Unit’s Pro- gramming Device, data is allocated from the first word starting with the Com- munications Unit’s Status Flags and then the leftmost I/O Unit’s data.
