Computing the Cycle Time
I/O Unit Refresh Time Coefficients for Units on CS1 Long-distance Expansion Racks
Factor
Special I/O Unit Refresh
504
Note Longer I/O refresh times will be required according to the distance from the
CPU Rack to the Unit when these Units are mounted to CS-series Long-dis-
tance Expansion Racks. Multiply the values given in the table by the factors
on line *1 in the following graph.
