The 1756 PMIO Scanner will slot into a ControlLogix backplane and provide input and output assemblies which are mapped  to various Honeywell TDC 3000® IO Processors (IOPs) allowing the Logix controller to own and control the legacy IO.

The PMIO Scanner also supports Honeywell TDC 3000® IO redundancy by providing two Honeywell IO Link connections via the two 3-way connectors on the front of the module.

The PMIO Scanner supports 3 Modes ofoperation:

  • Run   - PMIO Scanner configures IOP, reads inputs & controls outputs
  • Shadow  - Listen only, provides Input & Output Readback values to Logix for checkout/testing
  • Learn  - Uploads configuration from existing pre-configured IOPs

Options to Add & Configure IOPs:

  • EB (Exception Build) File Import
  • Online Learn Option
  • Manual Configuration

Within the Slate environment each IOP can be configured to match the application.

The following IOPs are currently supported:

  • HLAI6 – High Level Analog Input Processor (16 channel)
  • AO16 – Analog Output Processor (16 channel)
  • DI – Digital Input Processor (32 channels)
  • DO16 – Digital Output Processor (16 channel)
  • DO32 – Output Processor (32 channel)
  • AO8 – Analog Output Processor (8 channel)
  • LLAI - Low Level Analog (8 channel)
  • LLMUX - Low Level Analog Input Multiplexer (32 channel)

The configuration of the IOPs and their respective IO points (channels) can be configured manually, imported from Honeywell EB (Exception Build) files, or scanned from an online Honeywell system.

To aid in migration, the PMIO Scanner provides a number of Operational Modes, including a Shadow mode where the PMIO Scanner can run in parallel with the HPM. In this mode the APM/HPM is controlling the IOPs and the PMIO is listening-in and providing the input data to the ControlLogix.
