snthakkar Posted March 8, 2012 Report Share Posted March 8, 2012 Does Jazz PLC have any retentive memory ? If yes, how to use it ? I want to be able to store certain values that can change in the program, but will remain in it's last state even after cycling power to PLC.

Ofir Posted March 8, 2012 Report Share Posted March 8, 2012 Hi, Jazz has ALL operands battery backup - expected for about 7 years! The operands values are kept and power failure will not affect it. Quote Link to comment Share on other sites More sharing options...
