The internal data bus structure facilitates real-time signal transfer between the primary CPU processor and high-density I\/O or smart option modules with zero latency overhead. Firmware flash compatibility within the Revision K hardware footprint ensures synchronous instruction fetching during dense ladder logic cycles. The module's backplane bus communication velocity is optimized to execute high-rate I\/O scan sweeps while preventing data corruption through hardware-enforced parity verification and backplane noise isolation filters.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the procedure for replacing the memory backup battery (IC697ACC701) on the IC697CPU771K module without losing program data?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Power must remain applied to the Series 90-70 backplane rack during battery replacement. Open the protective front cover of the module, detach the existing lithium battery connector from the main CPU board, and attach the replacement IC697ACC701 battery. If power is interrupted while the battery is disconnected, volatile CMOS RAM contents will be cleared unless backed up to non-volatile memory.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the IC697CPU771K module be inserted into or removed from the VME backplane while the rack power supply is energized?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. The GE Series 90-70 VME backplane does not support hot-swapping for CPU modules. Power to the rack assembly (IC697CHS750, 782, 783, 790, 791) must be switched off prior to inserting or removing the IC697CPU771K to prevent backplane bus faults or hardware damage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Which programming software packages support configuration and downloading to the IC697CPU771K via the serial interface?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Program configuration and downloads are executed using Logicmaster 90-70 (MS-DOS\/Windows), VersaPro Professional Edition, or Proficy Machine Edition Logic Developer PLC Professional Edition.
