Problem 17. PLC VFD 1-D stage LLS RLS RLS 0 LLS 0 TE TR The logic for a control bit A is A= R+L A Micrologix 1000 CTU counter module with counter enable CU and counter control relay CDN will be used to count the number of times the carriage energizes LLS. To do that, each time TE has a negative edge, the counter module's accum is incremented. Before the counter's accum reaches its preset, we want to force control bit A = O·The control logic that needs to be added to A is A=(R + L) + CDN A- (R+ L)+CDN A. A= (R + L) . CDN B. A (R+L) CDN C. D.
