Backplane Bus Interfacing and Deterministic Networks

The IC693DNM200 connects directly to the main rack backplane bus of Series 90-30 or PACSystems RX3i CPUs, utilizing high backplane bus communication velocity to process up to 3972 bytes of input and output data. Network synchronization across DeviceNet deterministic networks is sustained through configurable Poll, Strobe, Cyclic, or COS messaging triggers. The module supports simultaneous dual Master/Slave execution, Unconnected Message Manager (UCMM) protocols, and on-the-fly firmware upgrades via the front RS-232 service port, maintaining firmware flash compatibility across active system revisions.

Frequently Asked Questions

Q: Which backplane baseplate slots support the IC693DNM200 module?

A: The module can be installed in any available slot of a Series 90-30 or RX3i main rack except slots 0 and 1. It is not supported in remote or expansion baseplates.

Q: What are the maximum current limits for the 32 discrete output channels?

A: Output points deliver up to 0.5 A per point. However, total current must not exceed 4.0 A per 8-point output group, and current per group common pin must stay below 3.0 A.

Q: Does the IC693DNM200 support firmware updates in the field?

A: Yes, module firmware is upgradeable via the front panel 9-pin RS-232 female service port using standard configuration software.

Field Installation Guidelines

  1. Remove primary power from the PLC rack and field power sources prior to inserting or removing the module.
  2. Wear an ESD grounding wrist strap connected to an unpainted metal enclosure frame during module handling.
  3. Seat the IC693DNM200 into an authorized slot of the main rack (excluding slots 0 and 1) until the chassis latches lock in place.
  4. Wire the DeviceNet network cable to the dedicated DeviceNet terminal block, placing 120 Ohm termination resistors at both physical ends of the trunk cable.
  5. Connect external 12 to 24 VDC positive logic power to the output terminals, ensuring total current draw per group common pin remains under 3.0 A.
