Notes: 1. Time (in microseconds) is based on Release 7 of Logicmaster 90-30/20/Micro software for Model 351 and 352 CPUs.

2.For table functions, increment is in units of length specified.; for bit operation functions, microseconds/bit.; for data move functions, microseconds/number of bits or words.

3.Enabled time for single length units of type %R, %AI, and %AQ.

4.COMMREQ time has been measured between CPU and HSC.

5.DOIO is the time to output values to discrete output module.

6.Where there is more than one possible case, the time indicated above represents the worst possible case.

7.For instructions that have an increment value, multiply the increment by (Length –1) and add that value to the base time.
