Notes:1. Time (in microseconds) is based on Release 5.01 of Logicmaster 90-30/20 software for Models 311, 313, 340, and 341 CPUs (Release 7 for the 331).
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.

for this information.
