Features:
- CPU-rack bus interface.
- Parallel programmer connector.
- Up to seven expansion racks.
CPU-rack bus interface establishes the principal capability of
IC697BEM713 within its Series 90-70 function.
The relationship between parallel programmer connector and up to seven expansion racks determines how the module fits the surrounding rack, network, or field circuit.
During service, 50 ft total inter-rack cable must remain consistent with the saved application and the installed hardware.

Transmitter placement in the main rack
- Rack location: IC697BEM713 belongs in the main CPU rack and may use any open slot except slot 1.
- Receiver pairing: Its expansion port feeds IC697BEM711 receivers installed at the head of each expansion rack.
- Rack reach: A single transmitter can extend the system to seven additional IC697 racks.
- Version condition: Version IC697BEM713A is positioned to the right of an IC697BEM731 when both modules are present.
Two distinct ports on IC697BEM713
- Programmer port: The upper connector provides the high-performance parallel path for the programming device.
- Expansion port: The lower connector launches the daisy-chained parallel bus toward the receiver modules.
- Cable boundary: The total path from the transmitter to the final receiver is limited to 15 m (50 ft).
- Port separation: Programmer traffic and rack expansion use different physical connectors on the module.
Reading transmitter activity
- Module LED: OK reports the operating state of IC697BEM713 itself.
- Programming activity: PGMR ACTIVE changes with traffic on the parallel programmer interface.
- Expansion activity: BUS ACTIVE identifies communication on the rack-expansion path.
- Troubleshooting order: The three indications separate a module problem from programmer-port or expansion-bus inactivity.
Bringing the bus transmitter online
- Power isolation: The CPU rack is de-energized before the module or either parallel cable is moved.
- Physical check: Both connectors are seated and strain-relieved according to their programmer and expansion roles.
- Software entry: IC697BEM713 is added to the Series 90-70 hardware configuration without DIP-switch settings.
- Startup result: Normal port indications are confirmed before relying on any attached expansion rack.
