Page 19: Drt2 Features
Section 1-1 DRT2 Features DRT2 Features 1-1-1 Overview The DRT2-series Smart Slaves can be used to collect various information that improves the operating rate of the equipment, in addition to performing basic input and output of ON/OFF signals. A maintenance system can be configured separately from the control system. This enables a balance between control and maintenance using an existing DeviceNet network, contributing to reduced startup time, shorter recovery time when problems occur, and preventative maintenance of the equipment.

Page 21 Section 1-1 DRT2 Features Operation Time Monitor The time that lapses from when the output turns ON to when the input turns ON can be measured at high speed from the Slave (without relying on the lad- der program). The Slave also maintains a set value for monitoring the opera- tion time, and will provide notification the Status Area if the set time is exceeded.
Page 22 Section 1-1 DRT2 Features Peak/Bottom Hold (Input The maximum (peak) and minimum (bottom) values input to Analog Input Ter- Units Only) minals can be held. These values can then be compared with alarm set val- ues, and flags turned ON as appropriate to indicate the status (comparator function).

Page 223 If there is nearby equipment that generates electrical noise, take steps to shield the Master, Slaves, and communications cables from the noise. If an error has occurred in a network with an OMRON Master Unit, refer to the Mas- ter Unit's Operation Manual.
Page 224: Maintenance
If another company’s Master is being used, refer to the relevant operation manual. Check whether the Slave is registered in the Master’s scan list. If an OMRON Master Unit is being used, a new Slave cannot be added to the network if the Master is operating with the scan list enabled.
Page 225: Inspection
After replacement make sure that there are no errors with the new Unit. When a Unit is being returned for repair, attach a sheet of paper detailing the problem and return the Unit to your OMRON dealer. If there is a faulty contact, try wiping the contact with a clean, lint-free cloth dampened with alcohol.
