The IC697PCM711 operates as an intelligent coprocessor running at 12 MHz, maintaining deterministic backplane bus communication velocity by handling real-time data processing independently from the main CPU. Through its dual serial ports, the module executes multi-protocol communication programs using CCM2 protocol structures. The integrated hardware interface offloads complex serial string manipulation and user-written algorithms from the main ladder scan, preserving scan-time predictability across the backplane bus while maintaining firmware flash compatibility with Series 90-70 controller racks.
Q: What is the backplane power consumption requirement for the IC697PCM711 module?
A: The IC697PCM711 draws 1 A at 5 VDC directly from the Series 90-70 backplane power supply rail.
Q: How are the serial ports configured on the front of the module?
A: The module features two serial ports that can be individually configured via hardware jumper/software settings for either RS-232 or RS-422/RS-485 serial communication modes.
Q: What maintains the user program and memory storage during power loss?
A: User RAM and application memory are maintained during main system power disruption by an onboard lithium battery, which features a shelf life rating of up to 10 years at 20 deg C.
