116-Channel - 24Vdc Diagnostic Input
Description Identifies the physical IOM for the CPM to provide links to associated IOC and provides selected diagnostic
information for associated channels.
Function • Defines type of IOM, number of channels, execution state, and communications path for data.
• Supports the following diagnostic, which is user configurable for each channel:
– Open Wire Detection: Senses when current input for a given channel falls below a certain value. When an
input uses dry contacts, you must include a bleed resistor in the input. You may not need a bleed resistor for
solid state contacts.
• Provides link to IOC through IO manager software resident in the CPM.
• Executes once every cycle.
• Includes IOC assignment to one of 16 channels (points), as part of IOM configuration.
Inputs Real-time data transmission from physical device.
Outputs Real-time data transmission to configured IOC.
